  4. DOption (d)

    5 + 2 × 6 ÷ 4 - 1 = 7

View answer & explanation

Correct answer

Answer: (d)D.

5 + 2 × 6 ÷ 4 - 1 = 7

Why this answer is correct

Option 1: 6 + 8 × 2 ÷ 4 - 5 = 14

interchanging the two numbers 5 and 2 we get:

6 + 8 × 5 ÷ 4 - 2 = 14

applying the BODMAS we get:

6 + 8 × 1.25 - 2 = 14

6 + 10 - 2 = 14

16 - 2 = 14

14 = 14

The given equation is correct.

Option 2: 8 + 6 × 2 ÷ 5 - 4 = 19

interchanging the two numbers 5 and 2 we get:

8 + 6 × 5 ÷ 2 - 4 = 19

applying the BODMAS we get:

8 + 6 × 2.5 - 4 = 19

8 + 15 - 4 = 19

23 - 4 = 19

19 = 19

The given equation is correct.

Option 3: 2 + 8 × 7 ÷ 4 - 5 = 17

interchanging the two numbers 5 and 2 we get:

5 + 8 × 7 ÷ 4 - 2 = 17

applying the BODMAS we get:

5 + 8 × 1.75 - 2 = 17

5 + 14 - 2 = 17

19 - 2 = 17

17 = 17

The given equation is correct.

Option 4: 5 + 2 × 6 ÷ 4 - 1 = 7

interchanging the two numbers 5 and 2 we get:

2 + 5 × 6 ÷ 4 - 1 = 7

applying the BODMAS we get:

2 + 5 × 1.5 - 1 = 7

2 + 7.5 - 1 = 7

9.5 - 1 = 7

8.5 ≠ 7

The given equation is not correct after interchanging the two numbers 5 and 2.

Hence, the correct answer is "Option 4".

Answer: (d)D.

320\sqrt{320} and South-West

Why this answer is correct

Drawing the Diagram as per the given information:

AC = 16 m

BC = 8 m

Thus the distance between point B from point A is given by Pythagoras Theorem.

Now, Triangle "ABC" is a right-angled triangle, so using Pythagoras Theorem: 

AB2 = AC2 + BC2 

AB2 = (16)2 + (8)2

AB2 = 256 + 64

AB2 = 320

AB = √320

The starting point is in a South-West direction with respect to B.

Hence, the correct answer is "√320 and South-West ".

  4. DOption (d)

    Only II

View answer & explanation

Correct answer

Answer: (a)A.

Both I and II

Why this answer is correct

The correct answer is Both I and II.

Key Points

  • The refraction of light by the Earth’s atmosphere is known as the atmospheric refraction of light.
  • The phenomena of atmospheric refraction are:
  • twinkling of stars
  • early Sunrise
  • delayed sunset
  • stars seem higher than actual height.

Important Points

  • Twinkling of stars: 
  • As the movements of air and convection currents cause a change in the density of the layers of air.
  • As a result, the position of the image of the star goes on to change after every short interval.
  • These different positions of the images formed at short intervals of time give the impression that the star is twinkling.
  • Advanced sunrise and delayed sunset
  • ​The Sun is visible a little before the actual sunrise and until a little after the actual sunset due to the refraction of light through the atmosphere.
  • The layers of air nearer to earth are denser than those above it.
  • At sunrise and sunset when the sun is below the horizon, the light rays starting from the sun are incident on these layers.
  • They pass through successively denser layers and thus get bent more and more towards the normal until they fall upon the eye of the observer.
  • To the observer, these rays appear to come from S’ which is above the horizon. It is for this reason that the sun is visible to us a little before it rises above the horizon and so also till a little later it sets below the horizon.
  • The difference in time is about 2 minutes each for an early rise and late setting of the Sun.

    None of the above

View answer & explanation

Correct answer

Answer: (d)D.

None of the above

Why this answer is correct

The correct answer is 'None of the above'.

Key Points

Tat Vadya:

  • These are stringed instruments.
  • Tat Vadya: We know that Tat Vadya refers to stringed instruments. Hence, associating Tat with "Air" would be incorrect.
  • Sound is produced by way of vibrating strings or strings stretched between two points.
  • These instruments are further classified into plucked, bowed, fretted, and non-fretted instruments.
  • Sound is produced by inducing the vibration of a taut string or chord by plucking or bowing.
  • The length of the string and the tension in it determines the pitch of the note and the duration of the sound.

String instruments can be classified based on the mode of play:

  • By friction with a bow like a sarangi, dilruba, esraj, etc. (Ravanastram is one of the earliest known bowed instruments);
  • By plucking the string like the Saraswati veena, Rudra veena
  • By striking with a hammer or a pair of sticks like gettuvadyam, swaramandala.

 

Avaanaddha Vadya:

  • These are percussion instruments. Sound is produced by a stretched membrane, such as a drum.
  • ​Avaanaddha Vadya: This refers to percussion instruments in the Indian musical tradition (source not provided in the links). Thus, linking Avaanaddha Vadya with "Wire" is also incorrect.
  • Membranophonic instruments act as skin-vibrators because they produce sound-waves by vibrations of a stretched skin or membrane when struck, plucked, or stroked.
  • A hollow vessel is covered with a membrane that generates beats when struck.

Percussion instruments can be classified by modes of playing:

  • Played by hand like mridangam
  • Played using sticks like nagara
  • Played partly by hand and partly by stick-like Tavil
  • Self struck like Damaru

  4. DOption (d)

    Money supply

View answer & explanation

Correct answer

Answer: (a)A.

Money multiplier

Why this answer is correct

The correct answer is Money multiplier.

Key Points

  • The money multiplier is defined as the ratio of the stock of money to the stock of high powered money in an economy, viz. M/H.
  • The money multiplier is the amount of money created by commercial banks for a given fixed amount of base money and reserve ratio.
  • An increase in the cash reserve ratio prevents the banks from lending more money and reduces the money multiplier.
  • An increase in the banking habit of the population will increase the lending, thereby will lead to more deposits in the banking system, hence increasing the money multiplier.
  • Even if there is an increase in the population of the country, the money multiplier in an economy does not necessarily increase.
  • The size of the money multiplier is determined by the currency ratio (Cr) of the public, the required reserve ratio (RRr) at the central bank, and the excess reserve ratio (ERr) of commercial banks. The lower these ratios are, the larger the money multiplier is.
  • The multiplier holds an inverse relationship with the reserve ratio.
  • Money Multiplier = 1 / Reserve Ratio

Let be assume the length and breadth of the rectangle is a and b respectively and the side of the equilateral triangle is p

⇒ 110 = 2 × (a + b)

⇒ a + b = 55     ----(1)

⇒ a - b = 5     ----(2)

⇒ By solving equations (1) and (2)

⇒ a = 30, b = 25

⇒ The area of rectangle = 30 × 25 = 750 cm2

⇒ The area of equilateral triangle = (√3/4) × (a2)

⇒ 750 = √3/4 × a2

⇒ 3000/√3 = a2

⇒ (1000 × 3 × 3-1/2)1/2 = a

⇒ (10000001/2 × 31/2)1/2 = a

⇒ 10000001/4 × 31/4 = a

⇒ 100001/4 × 1001/4 × 31/4 = a

⇒ 10 × 3001/4 cm = a

∴ The required result will be  10 × 3001/4 cm.

28.56

Why this answer is correct

Given:

P = 9A

A = 7A

Concept:

The gain marks percentage = {(Total gain marks)/(Total marks)} × 100

Calculation:

⇒ The required percentage = {(P - Q)/(Q)} × 100

⇒ ((9A - 7A)/7A} × 100 = (2A/7A) × 100 = 28.56%

∴ The required result will be 28.56%.

  4. DOption (d)

    37.43

View answer & explanation

Correct answer

Answer: (c)C.

45.45

Why this answer is correct

Given:

The ratio of cost price and selling price of article = 11 : 16

Concept:

Profit percentage = {(Selling price - Cost price)/Cost price} × 100

Calculation:

Let the cost price and selling price of the article be 11x and 16x respectively

According to the question,

⇒ New cost price = 11x × (120/100) = 66x/5

⇒ New selling price = 16x × (120/100) = 96x/5

⇒ The profit percentage = {(96x/5 - 66x/5)/(66x/5)} × 100 = (30/66) × 100

⇒ (0.4545) × 100 = 45.45%

∴ The required result will be 45.45%.

View answer & explanation

Correct answer

Answer: (b)B.

Rs. 3200

Why this answer is correct

Given:

The simple interest = 1280

The time = 4 years

Concept:

Simple interest = (Principle × Time × Rate)/100

Calculation:

Let be assume the sun is X and the rate of interest is R

⇒ 1280 = (X × 4 × R)/100

⇒ 32000 = XR  

⇒ Let be assume simple interest is I for 10 years let be assume

⇒ I = (X × R × 10)/100

⇒ I = (32000 × 10)/100 = 3200

∴ The required result will be 3200.

View answer & explanation

Correct answer

Answer: (c)C.

x2 ∶ z2

Why this answer is correct

Given:

 x ∶ y = y ∶ z

Concept:

If a : b = b : c then,

b2 = ac

Calculation:

⇒ x ∶ y = y ∶ z

⇒ y2 = xz

⇒ x ∶ y = y ∶ z

⇒ (x/y)4 = (y/z)4

⇒ x4/y4 = y4/z4

⇒ x4/y4 = (xz)2/z4

⇒ x4/y4 = x2/z2

∴ The required result will be x2 : z2.

  2. BOption (b)

    45 minutes

  3. COption (c)

    75 minutes

  4. DOption (d)

    60 minutes

View answer & explanation

Correct answer

Answer: (b)B.

45 minutes

Why this answer is correct

Given:

The distance = 30 km

The time = 36 minutes

Concept:

Speed = Distance/Time

Calculation:

⇒ Let speed of bus be S

⇒ S = 30/(36/60) = (30 × 60)/36 = 50 km/h

⇒ Now, speed reduce by 10 km/h then time taken by bus to cover same distance

⇒ Time = 30/(50 - 10) = 30/40 = 3/4 hours = (3/4) × 60 = 45 minutes

∴ The required result will be 45 minutes.

Question 49

The line chart given below shows the marked price and selling price of six articles A, B, C, D, E and F.

    29

  2. BOption (b)

    69

  3. COption (c)

    40

  4. DOption (d)

    20

View answer & explanation

Correct answer

Answer: (c)C.

40

Why this answer is correct

Given:

The marked price of C = 450

The selling price of C = 425

The marked price of D = 362

The selling price of D = 318

The marked price of E = 435

The selling price of E = 420

Calculation:

⇒ J1 = (450 - 425) + (362 - 318) = 25 + 44 = 69

⇒ J2 = (362 - 318) - (435 - 420) = 44 - 15 = 29

⇒ J1 - J2 = 69 - 29 = 40

∴ The required result will be 40.

    7 ∶ 1

  3. COption (c)

    7 ∶ 3

  4. DOption (d)

    7 ∶ 2

View answer & explanation

Correct answer

Answer: (b)B.

7 ∶ 1

Why this answer is correct

Given:

The difference between two numbers = 75% of the sum of the numbers

Concept:

If two number is A and B then,

A - B = (75/100) × (A + B)

Calculation:

Let be assume the larger number is A and the smaller number is B

⇒ A - B = (75/100) × (A + B)

⇒ 4A - 4B = 3A + 3B

⇒ 4A - 3A = 3B + 4B

⇒ A/B = 7/1 = 7 : 1

∴ The required result will be 7 : 1.

Question 51

Which of the following statement is correct?

I. A boat travels 84 km downstream and 42 km upstream. If speed of boat and speed of stream are 6 km/hr and 2 km/hr respectively, then total time taken is 20 hours.

II. Length of a platform is 1200 meters. If a 600 meter long train can cross it in 30 seconds, then speed of train is 54 km/hr.

  1. AOption (a)

    Only II

  2. BOption (b)

    Neither I nor II

  3. COption (c)

    Only I

  4. DOption (d)

    Both I and II

View answer & explanation

Correct answer

Answer: (b)B.

Neither I nor II

Why this answer is correct

Given:

Speed of boat = 6 km/h

Speed of stream = 2 km/h

Upstream distance = 42 km

Downstream distance = 84 km

The length of the platform = 1200

The length of the train = 600

Concept:

Upstream speed = Speed of the boat - Speed of the stream

Downstream speed = Speed of the boat + Speed of the stream

Speed = Distance/Time

Calculation:

For statement l

⇒ 42/(6 - 2) + (84)/(6 + 2) = 42/4 + 84/8 = 10.5 + 10.5 = 21 hours

⇒ Hence, statement l is wrong

For statement ll

⇒ Let be assume length of the platform is X

⇒ 30 = (600 + X)/(54 × 5/18) 

⇒ 30 = (600 + X)/15

⇒ 450 = 600 + X

⇒ X = 600 - 450 = 150

⇒ Hence, statement ll is wrong

∴ The required result will be "Neither I nor II".

Concept:

If √A then,

√A = A2

Calculation:

⇒ ∛(0.02 + √0.000049)

⇒ ∛{0.02 + (49/106)1/2}

⇒ ∛ (0.02 + 7/1000)

⇒ ∛{(20 + 7)/1000}

⇒ (27/1000)1/3 = 3/10

⇒ 0.3

∴ The required result will be 0.3.

  4. DOption (d)

    55 cm

View answer & explanation

Correct answer

Answer: (a)A.

105 cm

Why this answer is correct

Given:

The six-time of the volume of a sphere = 29106 cm3

Concept:

The volume of the sphere = (4/3) × π × (The radius of the sphere)3

Calculation:

Let be assume the radius of the sphere is R

⇒ 29106 = 6 × {(4/3) × (22/7) × R3}

⇒ 29106/6 = (88/21) × R3

⇒ (4851 × 21)/88 = R3

⇒ 1157.625 = R3

⇒ R = ∛(1157.625) = 10.5 cm

⇒ The ten time of the radius of the sphere = 10 × 10.5 = 105 cm

∴ The required result will be 105 cm.

If a : b = x : y then,

a = bx/y

Calculation:

⇒ a : b = 2 : 3

⇒ a = 2b/3

⇒ (b2 + 2a2) ∶ (b2 - 2a2)

⇒ {b2 + 2 × (2b/3)2} : {b2 - 2 × (2b/3)2}

⇒ (9b2 + 8b2)/9 : (9b2 - 8b2)/9

⇒ 17b2/b2 = 17/1 = 17 : 1

∴ The required result will be 17 : 1.

Why this answer is correct

Given:

A/B = 11/9

Concept:

If a : b = x : y then, 

a = bx/y

Calculation:

⇒ A/B = 11/9

⇒ A = 11B/9

⇒ (A - B)/(A + B) = (11B/9 - B)/(11B/9 + B) 

⇒ (2B/9) ÷ (20B/9) = 2B/20B = 1/10

∴ The required result will be 1/10.

Why this answer is correct

Given:

10 men working 4 hours per day can do a work = 15 days

Concept:

Work = Time × Efficiency 

Calculation:

Let be assume the remaining work will be done in X days

⇒ (10 Men × 15 Days × 4 Hours) = (5 Days × 10 Men × 4 Hours) + (X Days × 6 Men × 4 Hours)

⇒ 600 = 200 + 24X

⇒ X = (600 - 200)/24 = 400/24 = 50/3

∴ The required result will be 50/3.

Concept:

The gain marks percentage = {(Gain marks)/(Total marks)} × 100

Calculation:

For statement l

⇒ The required % = {(8.3 - 7.6)/7.6} × 100 = (0.7/7.6) × 100 = (0.092) × 100 = 9.2

⇒ Hence, statement l is correct

For statement ll

⇒ The required % = {(7.6 - 6.8)/6.8} × 100 = (0.8/6.8) × 100 = (0.1176) × 100 = 11.76%

⇒ Hence, Statement ll is correct

For statement lll

⇒ The required percentage = {(8.3 - 6.8)/6.8} × 100 = (1.5/6.8) × 100 = (0.2205) × 100 = 22.05%

⇒ Hence, statement lll is wrong

∴ The required result will be "Both l and ll".

Direction: Read the following information carefully and answer the given questions.

Initiatives such as “4 per mille” and Terraton aim to sequester huge amounts of carbon in the soil. The 2018 U.S. Farm Bill includes the first-ever incentives for farmers to adopt practices aimed at improving soil health and sequestering carbon. But these initiatives are missing a key point: not all soil carbon is the same.

The very different lifetimes of particulate organic matter and mineral-associated organic matter have important implications for these efforts. For example, adding low-quality crop residues to agricultural fields would likely create more particulate organic matter than mineral-associated organic matter. This could increase soil carbon in the short term - but if that field later is disturbed by tilling, a lot of it would decompose and the benefit would be quickly reversed. The best practices focus on building up the mineral-associated organic matter for longer-term carbon storage, while also producing high-quality particulate organic matter with lots of nitrogen to help boost crop productivity.

Natural healthy soils show us that providing continuous and diverse plant inputs that reach all the way to deep soil is key for achieving both high mineral-associated organic matter storage and particulate organic matter recycling. There are many promising ways to do this, such as maintaining plant cover on fields year-round; growing diverse crops that include high-nitrogen legumes and perennials with deep roots; and minimizing tillage.

However, not all soils can accumulate both mineral-associated organic matter and particulate organic matter. Before implementing any management practices for carbon sequestration, participants should first assess the carbon storage potential of the local soil, much as a doctor studies a patient before prescribing a cure. Sequestering soil carbon effectively requires an understanding of how particulate organic matter and mineral-associated organic matter work, how human actions affect them, and how to build up both types to meet our planet’s climate and food security needs.

Question 76

What conclusion can be drawn from the given passage?

  1. AOption (a)

    Food security is as essential as maintaining the appropriate weather and necessary management strategies must be followed.

  2. BOption (b)

    Minimum usage of low-quality carbon should be done in agricultural field as it

    affects the climate.

  3. COption (c)

    It’s important to keep the check on human action as it affects sequestration of soil

    carbon.

  4. DOption (d)

    To meet our food security and climate needs proper balance between mineral and particulate based organic matter is required, considering human interaction.

View answer & explanation

Correct answer

Answer: (d)D.

To meet our food security and climate needs proper balance between mineral and particulate based organic matter is required, considering human interaction.

Why this answer is correct

The correct answer is 'To meet our food security and climate needs proper balance between mineral and particulate based organic matter is required, considering human interaction.'

Key Points

  • Let's refer to the following lines of the passage:
  • Sequestering soil carbon effectively requires an understanding of how particulate organic matter and mineral-associated organic matter work, how human actions affect them, and how to build up both types to meet our planet’s climate and food security needs.
  • From above, we can refer that the correct answer is option 4.

Question 77

What inference can be drawn from the statement ‘doctor studies a patient before prescribing a cure’ in respect of the given passage?

  1. AOption (a)

    Before giving prescription to a patient, his allergies to the medicine must be

    checked.

  2. BOption (b)

    Before preparing the soil for carbon sequestration, its potential should be checked.

  3. COption (c)

    Just like a farmer in agricultural field, doctor is required to check the patient.

  4. DOption (d)

    All soils cannot accumulate particulate organic matter with great efficiency.

View answer & explanation

Correct answer

Answer: (b)B.

Before preparing the soil for carbon sequestration, its potential should be checked.

Why this answer is correct

The correct answer is 'Before preparing the soil for carbon sequestration, its potential should be checked.'

Key Points

  • Let's refer to the following lines of the passage:
  • Before implementing any management practices for carbon sequestration, participants should first assess the carbon storage potential of the local soil, much as a doctor studies a patient before prescribing a cure.
  • Thus, from above we can infer that just like when a doctor prescribes a medicine he/she performs an examination to know the type of disease or problem that patient has, the potential of soil to store carbon should be assessed before implementing any management practices.
  • Therefore, the correct answer is option 2.

Question 78

What is the central idea of the given passage?

  1. AOption (a)

    To know the importance of sequestering soil carbon.

Question 104

Which statements is correct regarding main () function in C++?

I. It is a user defined function.

II. It is a pre-defined function.

  1. AOption (a)

    Neither I nor II

  2. BOption (b)

    Only II

  3. COption (c)

    Both I and II

  4. DOption (d)

    Only I

View answer & explanation

Correct answer

Answer: (d)D.

Only I

Why this answer is correct

The correct answer is: Only I

Explanation:

I. It is a user-defined function: This is true. In C++, the main() function is written by the programmer, and its code block contains the instructions that the programmer wants the program to execute. It's where the program starts execution, so it's defined by the user in that sense.

II. It is a pre-defined function: This is false. The main() function is not pre-defined. The C++ language doesn't provide a default implementation for it. It must be defined by the programmer. However, its name and the fact that the program's execution starts there are predetermined by the language's standards, which could lead to some confusion. But strictly speaking, in terms of its implementation, it's not a pre-defined function.

  • Accuracy: Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy.
  • Diligence: A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration. Its memory also makes it superior to that of human beings.
  • Versatility: It refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency.
  • Reliability: A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result.
  • Automation: Computer performs all the tasks automatically i.e., it performs tasks without manual intervention.
  • Memory: A computer has built-in memory called primary memory where it stores data. Secondary storage are removable devices such as CDs, pen drives, etc., which are also used to store data.

Hence, the correct answer is option 4.

Question 106

    getchar ()

  2. BOption (b)

    getche ()

  3. COption (c)

    puts ()

  4. DOption (d)

    cgets ()

View answer & explanation

Correct answer

Answer: (d)D.

cgets ()

Why this answer is correct

cgets()

get a string of characters directly from the console.

Example:

#include <conio.h>

char *cgets( char *buf );

<br>

Description:

  • The cgets() function gets a string of characters directly from the console and stores the string and its length in the array pointed to by buf. The first element of the array, buf[0], must contain the maximum length in characters of the string to be read. The array must be big enough to hold the string, a terminating null character, and two additional bytes.
  • The cgets() function reads characters until a newline character is read, or until the specified number of characters is read. The string is stored in the array starting at buf[2]. The newline character, if read, is replaced by a null character. The actual length of the string read is placed in buf[1].

Returns:

A pointer to the start of the string, which is at buf[2].

Hence, the correct answer is option 4.

Question 107

What is the output of the following code written in C?

void main()

{

printf("%d%d%d",62,062,0x62);

}

  1. AOption (a)

    506298

  2. BOption (b)

    629850

  3. COption (c)

    625098

  4. DOption (d)

    986250

View answer & explanation

Correct answer

Answer: (c)C.

625098

Why this answer is correct

The output of the given C code will be - 625098

Explanation:

  1. The first value to be printed is 62, which is in decimal format. Therefore, its value is 62.
  2. The second value to be printed is 062, which is in octal format. The prefix '0' before the number indicates that it is an octal value. The octal value 062 is equal to the decimal value 50, so the second value printed is 50.
  3. The third value to be printed is 0x62, which is in hexadecimal format. The prefix '0x' before the number indicates that it is a hexadecimal value. The hexadecimal value 0x62 is equal to the decimal value 98, so the third value printed is 98.
  4. Finally, the printf() statement combines these three values and prints them without any separator, resulting in the output 625098.

Question 108

Consider the following segment of C++ code.

int j, n;

for(j=1;j<=n; )

j=j*2;

What is the number of comparisons made in the execution of the loop for any n > 0?

  1. AOption (a)

    log2(n + 1)

  2. BOption (b)

    log2 n + 1

  3. COption (c)

    n + 1

  4. DOption (d)

    (n + 1)/2

View answer & explanation

Correct answer

Answer: (b)B.

log2 n + 1

Why this answer is correct

The given loop in the C++ code is an example of an iterative process that doubles the value of j in each iteration until j becomes greater than n.

  • The number of comparisons made in the execution of the loop depends on the value of n. If we assume that n is a power of 2, then the loop will execute log2(n) times.

 

For example, if n = 8, the loop will execute 3 times:

  • In the first iteration, j is initially 1, and is doubled to 2.
  • In the second iteration, j is 2, and is doubled to 4.
  • In the third iteration, j is 4, and is doubled to 8.
  • After this, the loop exits after checking the condition because j is greater than n. Hence, 1 time more the condition will be checked.

 

In general, if n = 2k for some integer k, then the loop will execute k times. This is because j will take on the values 20, 21, 22, ..., 2(k-1) before becoming greater than n. As for the number of comparisons made, each iteration of the loop performs a single comparison (j<=n), so the total number of comparisons made will be equal to the number of iterations of the loop, which is log2(n) for n = 2k. Therefore, the answer is log2(n) + 1 for any n > 0.

Question 109

What is the maximum running time of the binary search algorithm, when n = 12,000?

  1. AOption (a)

    12

  2. BOption (b)

    15

  3. COption (c)

    13

  4. DOption (d)

    14

View answer & explanation

Correct answer

Answer: (d)D.

14

Why this answer is correct

Binary Search Algorithm - It is a search algorithm used to find the position of a target value within a sorted array or list. It works by repeatedly dividing the search interval in half until the target value is found or the interval becomes empty. It has a logarithmic time complexity of O(log n).

  • The maximum running time of the binary search algorithm occurs when the target element is either the first or the last element in the array, or when it is not present in the array at all.
  • In the worst-case scenario, the binary search algorithm performs log2(n) iterations to locate the target element in a sorted array of size n. Therefore, the maximum running time of the binary search algorithm for an array of size n = 12,000 is log2(12,000) = 13.87 (rounded up to 14).
  • This means that the binary search algorithm will take at most 14 iterations to locate the target element in the worst-case scenario. Since each iteration involves dividing the search space in half, the number of elements that need to be examined in each iteration is halved, resulting in a logarithmic time complexity of O(log n).
  • Therefore, the maximum running time of the binary search algorithm for an array of size n = 12,000 is O(log 12,000) = O(14) = O(1).

Question 110

View answer & explanation

Correct answer

Answer: (b)B.

-1

Why this answer is correct

The correct answer is  -1.

Key Points

  • if tan(A+ iB) = x+ iy
  • then tan(A-iB) = x - iy
  • Now, we can write
  • tan(2A)tan(2A) =tan[(A+iB)+(A−iB)]tan[(A+iB) + (A- iB)]

                   

                    =  (tan(A+iB)+tan(A−iB))(1−tan(A+iB)tan(A−iB)) (tan(A + iB) + tan(A - iB))\over(1 - tan(A + iB) tan(A - iB))

<br>

                     =  (x+iy+x−iy)(1−(x+iy)(x−iy))(x + iy + x - iy)\over(1 - (x + iy)(x - iy))

<br>

                     =     (2x)(1−x2−y2) (2x)\over(1 - x ^ 2 - y ^ 2)

  • Now we know we can write tan(2A)tan(2A)  as 1cot(2A)1\over cot(2A) therefore,
<br>

                   1cot(2A)1\over cot(2A) = (2x)(1−x2−y2) (2x)\over(1 - x ^ 2 - y ^ 2), 

             

                   1−x2−y2=2x(cot(2A)1-x^2-y^2 =2x(cot(2A)

                1=x2+y2+2xcot(2A)1= x²+ y²+2xcot(2A)

  • Now, Since x2+y2+2xcot(2A)=1x²+ y²+2xcot(2A) =1  ,Then   
  • x2+y2+2xcot2A−2=x^2 + y^2 + 2xcot 2A - 2 =  1-2

                                    = -1

  • ​Hence the correct answer is -1.

Why this answer is correct

  • The controlled electronic switch fabricated using a semiconductor is known as a "transistor."
  • A transistor is a type of semiconductor device that can be used to amplify or switch electronic signals.
  • It is made up of three layers of semiconductor material, which are typically composed of silicon, and can be either N-type (with an excess of negatively charged electrons) or P-type (with a deficiency of electrons).
  • The three layers of a transistor are called the emitter, base, and collector.
  • By applying a voltage to the base, the transistor can be switched on or off, allowing a current to flow between the emitter and collector terminals.
  • This makes the transistor a highly versatile device that can be used in a variety of electronic circuits.

  3. COption (c)

    Both I and II

  4. DOption (d)

    Neither I nor II

View answer & explanation

Correct answer

Answer: (d)D.

Neither I nor II

Why this answer is correct

Statement 1: The largest four-digit number in base 7 is 7777.

  • A number can not have any digit greater than or equal to its base. Hence, the number with base 7 can comprise only {0,1,2,3,4,5,6}.
  • Here, 6 is the maximum digit, so the largest four-digit number will be - (6666)7

 

Statement 2: The smallest four-digit number in base 8 is 1111.

  • The number with base 8 can have only {0,1,2,3,4,5,6,7} as its digits.
  • This statement is incorrect. In base 8 (octal system), the smallest four digit number would be 1000 (represented as 512 in the decimal system).
  • Remember, the numbering starts from zero so the smallest non-zero digit is 1 and the first four-digit number would be when that 1 is in the thousandths place.

Answer: (b)B.

1

Why this answer is correct

  • To find the minimum value, we need to differentiate it to check its behaviour.
  • Given y = x2, dydx=2x\frac{dy}{dx} = 2x
  • 2x will be positive (2x > 0) always in the interval [1,5].
  • Hence, y will also be increasing in this interval.
  • 1 is the minimum value in the interval [1,5].
  • Hence, y = x2 = 12 = 1.

Answer: (d)D.

Compiler

Why this answer is correct

The correct option is 4) Compiler.

  • A compiler is a system software package that converts a high-level language program into machine language or executable code.
  • It takes the source code written in a high-level language like C++, Java, or Python, and translates it into machine code that can be executed by the computer's processor.
  • The process of compilation involves several steps, including lexical analysis, syntax analysis, semantic analysis, code generation, and optimization.
  • During lexical analysis, the source code is broken down into a sequence of tokens or symbols.
  • In the syntax analysis phase, the tokens are parsed according to the grammar of the programming language to form a parse tree.
  • In the semantic analysis phase, the meaning of the code is checked to ensure that it is well-formed and complies with the rules of the language.
  • Finally, the code is generated and optimized to produce efficient machine code.

(30 – 20) × 40 = (1 - 1) x 1 = 0 x 1 = 0

(30 – 20) × (30 + 20) = (1 - 1) x (1 + 1) = 0

Hence, the correct option is 2.

  4. DOption (d)

    TCP/IP uses checksum to check error correction.

View answer & explanation

Correct answer

Answer: (b)B.

Data packets sent over TCP/IP are private.

Why this answer is correct

The correct answer is Data packets sent over TCP/IP are private.

Key Points

  • Transmission Control Protocol (TCP) is a communications standard that enables application programs and computing devices to exchange messages over a network.
  • It is designed to send packets across the internet and ensure the successful delivery of data and messages over networks.
  • TCP guarantees the integrity of the data being communicated over a network. Before it transmits data, TCP establishes a connection between a source and its destination, which it ensures remains live until communication begins.
  • It then breaks large amounts of data into smaller packets, while ensuring data integrity is in place throughout the process.
  • Data packets sent over TCP/IP are not private, which means they can be seen or intercepted. Hence option 2 is correct.
  • So, it is recommended to avoid using public Wi-Fi networks to send private data and ensure information is encrypted. One way to encrypt data being shared through TCP/IP is through a virtual private network (VPN).
  • TCP/IP communications provide end-to-end error checking of data transmission for reliable and sequential exchange of data, guarantees the sequential delivery of data packets and so it comes with high latency.

Additional Information

  • Error control in TCP is mainly done through the use of three simple techniques: Checksum, Acknowledgement and Retransmission.
  • Every segment contains a checksum field which is used to find corrupted segments. If the segment is corrupted, then that segment is discarded by the destination TCP and is considered lost.
  • In acknowledgement affirm that the data segments have been delivered. Control segments that contain no data but have sequence numbers will be acknowledged as well but ACK segments are not acknowledged.
  • In retransmission, when a segment is missing, delayed in delivering to a receiver or corrupted when it is checked by the receiver then that segment is retransmitted again.
  • Segments are retransmitted only during two events: when the sender receives three duplicate acknowledgements (ACK) or when a retransmission timer expires.
  • ​ High-level protocols that need to transmit data like File Transfer Protocol (FTP), Secure Shell (SSH), and Telnet use TCP Protocol.

    II and III

  4. DOption (d)

    I and II

View answer & explanation

Correct answer

Answer: (b)B.

I and III

Why this answer is correct

Concept:

There are three types of communication channels:

Simplex mode

In this communication channel only sends information in one direction. For example, a radio station usually sends signals to the audience but never receives signals from them, thus a radio station is a simplex channel. It is also common to use the simplex channels in fiber optic communication. One stand is used for transmitting signals and the other is for receiving signals. But this might not be obvious because the pair of fiber strands are often combined into one cable. The good part of simplex mode is that its entire bandwidth can be used during the transmission.

Half-duplex mode

Data can be transmitted in both directions on a signal carrier except not at the same time. At a certain point, it is actually a simplex channel whose transmission direction can be switched. A walkie-talkie is a typical half-duplex device. It has a “push-to-talk” button which can be used to turn on the transmitter but turn off the receiver. Therefore, once you push the button, you cannot hear the person you are talking to but your partner can hear you. An advantage of half-duplex is that the single track is cheaper than the double tracks.

Full-duplex mode

In this communication channel is able to transmit data in both directions on a signal carrier at the same time. It is constructed as a pair of simplex links that allow bidirectional simultaneous transmission. Take the telephone as an example, people at both ends of a call can speak and be heard by each other at the same time because there are two communication paths between them. Thus, using the full-duplex mode can greatly increase the efficiency of communication.

Half simplex is not a mode of transmission Therefore Option 2 is correct

Question 124

According to _______ law, the force between two charges is directly proportional to the product of their charges.

  1. AOption (a)

    Coulomb’s

  2. BOption (b)

    Kirchoff’s

  3. COption (c)

    Ohm’s

  4. DOption (d)

    Gauss’s

View answer & explanation

Correct answer

Answer: (a)A.

Coulomb’s

Why this answer is correct

Coulomb's law: Coulomb's law states that the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

  • The electrostatic force F between two point charges q1 and q2 separated by a distance r is given by: F=k×(q1×q2)r2F = k \times \frac{(q_1 \times q_2)}{r^2}  where k is Coulomb's constant, which has a value of approximately 9 x 109 Nm2C-2.

Kirchhoff's law: Kirchhoff's laws are two laws that deal with the conservation of charge and energy in electrical circuits. They are used to determine the voltages, currents, and resistances in a circuit.

  • Kirchhoff's current law (KCL) states that the total current entering a junction in an electrical circuit is equal to the total current leaving the junction.
  • Kirchhoff's voltage law (KVL) states that the total voltage around any closed loop in an electrical circuit is zero.

Ohm's law: Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

  • The current I flowing through a conductor between two points is directly proportional to the voltage V across the two points and inversely proportional to the resistance R of the conductor. Mathematically, this can be expressed as I=VRI = \frac{V}{R}

Gauss's law: Gauss's law relates the distribution of electric charge to the resulting electric field. It states that the total electric flux through any closed surface is proportional to the total electric charge enclosed within that surface. So, the correct option is Coulomb's law.

  • The total electric flux ΦE through any closed surface is equal to the net electric charge enclosed by that surface divided by the permittivity of free space ε0. Mathematically, this can be expressed as: ΦE=Qε0ΦE = \frac{Q}{ε_0} where Q is the total electric charge enclosed by the surface.

Question 125

crossing has to be closed. Which gate can be used to implement this?

  1. AOption (a)

    AND

  2. BOption (b)

    NAND

  3. COption (c)

    OR

  4. DOption (d)

    NOR

View answer & explanation

Correct answer

Answer: (c)C.

OR

Why this answer is correct

Train 1Train 2Crossing
YesYesClose
YesNoClose
NoYesClose
NoNoOpen

 

A gate that can be used to implement the given condition is the OR gate.

The OR gate has two or more input signals and produces an output signal when at least one of its input signals is high (logic 1). In this case, the input signals would be the presence of a train on each of the four railway tracks, and the output signal would indicate whether the crossing should be closed or not.

Therefore, if we connect the outputs of sensors placed at each track to the inputs of the OR gate, the output of the OR gate will be high (logic 1) if at least one of the sensors detects the presence of a train on its track. This can be used to trigger the closing of the railway crossing gates.

    zero

  3. COption (c)

    moderate

  4. DOption (d)

    high

View answer & explanation

Correct answer

Answer: (d)D.

high

Why this answer is correct

When data is frequently added to or deleted from a file, the volatility of the file is high.

  • This is because the file is constantly changing, and its content is not stable over time.
  • As new data is added, the file size increases, and the location of existing data may shift.
  • Similarly, as data is deleted, the file size decreases, and gaps may be created between the remaining data. T
  • his makes it difficult to predict the location of data within the file, and can lead to fragmentation and inefficiencies in accessing the data

Question 130

  2. BOption (b)

    Both I and II

  3. COption (c)

    Neither I nor II

  4. DOption (d)

    Only I

View answer & explanation

Correct answer

Answer: (b)B.

Both I and II

Why this answer is correct

Sequential file organization

  • Records are stored and accessed in a particular order sorted using a key field.
  • Retrieval requires searching sequentially through the entire file record by record to the end.
  • Because the record in a file is sorted in a particular order, better file searching methods like the binary search technique can be used to reduce the time used for searching a file.
  • Since the records are sorted, it is possible to know in which half of the file a particular record being searched is located, hence this method repeatedly divides the set of records in the file into two halves and searches only the half on which the records are found.
  • For example, of the file has records with key fields 20, 30, 40, 50, 60 and the computer is searching for a record with key field 50, it starts at 40 upwards in its search, ignoring the first half of the set.

Advantages of sequential file organization

  • The sorting makes it easy to access records.
  • The binary chop technique can be used to reduce record search time by as much as half the time taken.

Disadvantages of sequential file organization

  • The sorting does not remove the need to access other records as the search looks for particular records.
  • Sequential records cannot support modern technologies that require fast access to stored records.
  • The requirement that all records be of the same size is sometimes difficult to enforce.

Hence, the correct answer is option 2.

    best fit

  4. DOption (d)

    internal fragmentation

View answer & explanation

Correct answer

Answer: (d)D.

internal fragmentation

Why this answer is correct

The answer is "Internal Fragmentation".

Explanation -

  • When memory is allocated to a process, it is usually done in fixed-sized blocks or partitions. If a process requests a certain amount of memory that is less than the size of the smallest available partition, it will be allocated the entire partition. This can lead to a situation where there is unused memory within the partition that is allocated to the process. This unused memory is called internal fragmentation.
  • Internal fragmentation occurs when memory is allocated in fixed-sized blocks, and the process that is allocated to the memory does not use all of the memory in the block. This can happen when the process requests memory that is smaller than the size of the block it is allocated. The unused memory within the block is wasted and cannot be used by other processes.
  • External fragmentation, on the other hand, occurs when there is enough total memory available to satisfy a process request, but it is not contiguous, and cannot be allocated to the process. This can happen when memory is allocated and deallocated in a way that leaves small gaps between blocks of allocated memory.
  • Best fit and worst fit are algorithms used to allocate memory to processes. The best fit allocates the smallest available block of memory that is large enough to satisfy a process request, while the worst fit allocates the largest available block of memory. These algorithms can help to reduce external fragmentation.

Question 144

Which page replacement algorithm has Belady’s anomaly?

  1. AOption (a)

    FIFO page replacement

  2. BOption (b)

    Least recent used page replacement

  3. COption (c)

    Optimal page replacement

  4. DOption (d)

    Not recently used page replacement

View answer & explanation

Correct answer

Answer: (a)A.

FIFO page replacement

Why this answer is correct

  • A page fault occurs when a page is not found in the memory and needs to be loaded from the disk
  • If a page fault occurs and all memory frames have been already allocated, then the replacement of a page in memory is required at the request of a new page; This is referred to as demand-paging
  • The choice of which page to replace is specified by a page replacement algorithm
  • The commonly used page replacement algorithms are FIFO, LRU, optimal page replacement algorithms, etc
  • Generally, on increasing the number of frames to a process’ virtual memory, its execution becomes faster as less number of page faults occur; Sometimes the reverse happens, that is, more numbers of page faults occur when more frames are allocated to a process; This most unexpected result is termed as Belady’s Anomaly
  • FIFO and random replacement algorithms suffer from Belady’s Anomaly

    they communicate through an elementary data item

  2. BOption (b)

    they communicate via a composite data

  3. COption (c)

    they share same global data areas

  4. DOption (d)

    they share their code

View answer & explanation

Correct answer

Answer: (c)C.

they share same global data areas

Why this answer is correct

Two modules are said to be common coupled in software design if they share the same global data areas.

  • Common coupling occurs when two or more modules share access to the same global data or resources, such as shared variables, files, or databases.
  • This type of coupling can lead to a high degree of interdependence between the modules,
  • as changes made by one module can affect the behavior of other modules that share the same resources.
  • As a result, common coupling can make software systems difficult to maintain, modify, and test,
  • and can also make it harder to isolate and diagnose faults when they occur.
  • Therefore, it is generally recommended to minimize the use of common coupling in software design.

Question 147

I. A provision is a charge against profit

II. Reserve is an appropriation of profit

  1. AOption (a)

    Neither I nor II

  2. BOption (b)

    Both I and II

  3. COption (c)

    Only I

  4. DOption (d)

    Only II

View answer & explanation

Correct answer

Answer: (b)B.

Both I and II

Why this answer is correct

Key Points

 Statement 1: A provision is a charge against profit:

  • A provision is an estimated amount set aside to cover a known liability or expense that is expected to arise in the future.
  • It is a charge against profit and is recorded as an expense in the income statement.
  • Provisions are usually based on estimates and are subject to revision based on actual outcomes.

Statement II: Reserve is an appropriation of profit:

  • A reserve is an amount set aside from profits for a specific purpose, such as to cover future contingencies or to invest in new projects.
  • It is an appropriation of profit, meaning that it is not a charge against profit like a provision.
  • Reserves are recorded in the equity section of the balance sheet and are not included in the income statement.

Hence, both Statement I and II are correct.

Additional Information 

In accounting, a "charge against profit" and an "appropriation of profit" are two different concepts that relate to how profits are treated in a company's financial statements.

Charge Against Profit:

  • A charge against profit is an expense that is recognized in the income statement and is deducted from the company's revenue to arrive at the net income.
  • Examples of charges against profit include salaries and wages, rent, depreciation, and interest expenses.
  • These expenses are deducted from the revenue to calculate the profit or loss for the period.

Appropriation of profit:

  • An appropriation of profit is an amount that is set aside from the profits and is not treated as an expense in the income statement.
  • Appropriations of profit are used for a variety of purposes, such as to create reserves for future contingencies, to pay dividends to shareholders, or to invest in new projects.
  • Appropriations of profit are not deducted from the revenue in the income statement; instead, they are recorded as a separate item in the equity section of the balance sheet.

    Compaction

  3. COption (c)

    Belady’s Anomaly

  4. DOption (d)

    External fragmentation

View answer & explanation

Correct answer

Answer: (a)A.

Internal fragmentation

Why this answer is correct

Concept:

Memory fragmentation is the memory which is not used and gets wasted. It means processes are not able to occupy the whole memory leading to some holes in the memory. This is memory fragmentation. It is of 2 types:

Internal Fragmentation

Internal fragmentation happens when the memory is split into mounted sized blocks. Whenever a method request for the memory, the mounted sized block is allotted to the method. just in case the memory allotted to the method is somewhat larger than the memory requested, When there is a memory wastage within the memory partition itself then it known as Internal fragmentation

Additional InformationExternal fragmentation 

External fragmentation happens when there’s a sufficient quantity of area within the memory to satisfy the memory request of a method. however the process’s memory request cannot be fulfilled because the memory offered is during a non-contiguous manner.

Answer: (b)B.

Neither I nor II

Why this answer is correct

Concept:

PERT and Gantt charts enable project managers to track tasks and project status. PERT charts display tasks in a network diagram, highlighting dependencies; Gantt charts show tasks and timelines in a bar graph.

Explanation:

PERT (Program Evaluation and Review Technique) charts are often part of planning, and project managers use them before the start of a project to determine the anticipated length of each task.

Characteristics of a PERT chart:

  • The project manager and team define all activities and tasks necessary to complete a project, estimate the time to complete each task, and develop a preliminary time frame.
  • In a network diagram, each task is in a separate box that shows its dependencies in relation to other tasks.
  • A PERT chart doesn’t have an x- or a y-axis, but each box shows the start and completion times for its task.

Gantt charts used for tracking the status of tasks and highlighting scheduling constraints. Project managers might also use them before a project to break down tasks into smaller tasks.

Characteristics of a Gantt chart:

  • Tasks appear in a linear fashion on a bar chart.
  • The layout makes it easy to see the expected duration of each task and the entire project.
  • Gantt charts are also useful for coordinating resources and scheduling team members.
  • When you look at a Gantt chart, the x-axis shows the timeline, and the y-axis displays the tasks.

Hence the correct answer is option 2.

View answer & explanation

Correct answer

Answer: (c)C.

Both I and II

Why this answer is correct

Key Points

 Statement I: All permanent accounts are balanced and carried forward to the next accounting period:

  • Permanent accounts, also known as real accounts, are those accounts that are not closed at the end of the accounting period.
  • Examples of permanent accounts include assets, liabilities, and equity accounts.
  • These accounts are balanced at the end of the accounting period, and the balance is carried forward to the next accounting period.

Statement II: The temporary accounts are closed at the end of the accounting period:

  • Temporary accounts, also known as nominal accounts, are accounts that are used to record revenue, expenses, gains, and losses for a specific accounting period.
  • Examples of temporary accounts include revenue accounts, expense accounts, and dividend accounts.
  • These accounts are closed at the end of the accounting period by transferring their balances to the retained earnings account or income summary account.

Hence, both statement I and II are correct.

Question 157

A module of a software is said to be logically cohesive if _______.

  1. AOption (a)

    all the elements of the module perform similar operations like error handling, data

    input etc

  2. BOption (b)

    if the set of functions of the module are all part of a procedure

  3. COption (c)

    different elements of the module cooperate to achieve a single function for example managing an employee’s pay roll

  4. DOption (d)

    all the elements of the module performs different operations alternatively

View answer & explanation

Correct answer

Answer: (a)A.

all the elements of the module perform similar operations like error handling, data

input etc

Why this answer is correct

Concept:

Cohesion

  • The degree to which the module's elements are functionally related is measured by cohesion.
  • It is the degree to which all elements directed towards performing a single task are contained in the component.

Functional Cohesion: 

  • The component contains every necessary element for a single computation.
  • The task and functions are carried out by functional cohesion.

Sequential Cohesion: Data flow occurs when one element outputs data that becomes the input for another element.

Communicational Cohesion: Two elements perform the same operation on the same input data or contribute to the same output data.

Procedural Cohesion: The order of execution is ensured by procedural cohesion elements. Actions are still insecurely linked and unlikely to be reused.

Temporal Cohesion: 

  • The timing of the elements connects them.
  • A module associated with temporal cohesion requires that all tasks be completed within the same time frame.

Coincidental Cohesion: 

  • The components are unrelated.
  • Other than their location in source code, the elements have no conceptual relationship.

Logically cohesive: A module of a software is said to be logically cohesive, if all the elements of the module perform similar operations like error handling, data

input etc. Hence option 1 is correct.

The correct option is (1)

Concept:-

Postfix notation:- In this notation the operator is written after the operand so, it is called postfix notation. (post-after). It is also known as suffix notation or, reverse polish notation.

Example,

Case-1 To add A to B, we can write as AB+ or BA+

Case-2 To subtract D from C, we have to write CD-

Explanation:

Postfix equivalent of (8+2) - 5

= (82+) - 5

= X - 5 [let 82+ = X]

=X5-

=82+5- [Postfix form]

Key Points

  • Postfix notation uses the computer system to calculate arithmetic expressions. Any expression after into the computer is first converted into postfix notation, stored in the stack, and then calculated.

  3. COption (c)

    22

  4. DOption (d)

    Error

View answer & explanation

Correct answer

Answer: (c)C.

22

Why this answer is correct

Answer - 22

Explanation -

  1. The program defines the main function with a void return type and no parameters.
  2. Inside the main function, two integer variables k and v are declared.
  3. The variable v is assigned the value 20 using the assignment operator =. At this point, v equals 20.
  4. The comma operator , is used to evaluate two expressions sequentially, and the value of the second expression is returned as the result of the comma operator.
  5. In this case, the first expression in the comma operator is the assignment v = 20, which assigns 20 to the variable v.
  6. The second expression in the comma operator is v + 2, which adds 2 to the value of v. Since v now equals 20, the value of v + 2 is 22.
  7. The entire expression (v = 20, v + 2) is then evaluated, which evaluates both sub-expressions separated by the comma operator, and the value of the entire expression is 22.
  8. The value of the entire expression (v = 20, v + 2) is then assigned to the variable k using the assignment operator =. So, the value of k becomes 22.
  9. Finally, the printf function is called to output the value of k using the %d format specifier, which formats the value of k as a decimal integer. The output of the program is 22.

Question 160

Which of the following is the main function of the memory management system?

  1. It keeps track of which parts of the memory are currently in use.

II. When memory is available, it allocates memory to the programs to be loaded.

    Only II

  2. BOption (b)

    Neither । nor II

  3. COption (c)

    Both I and II

  4. DOption (d)

    Only I

View answer & explanation

Correct answer

Answer: (c)C.

Both I and II

Why this answer is correct

Statement 1 - It keeps track of which parts of the memory are currently in use

Explain - The system needs to keep track of which parts of memory are currently in use by which program or process, in order to avoid conflicts or memory access violations. This helps prevent programs from overwriting or accessing memory that is already in use by another program, which could lead to data corruption or system crashes.

Statement 2 - When memory is available, it allocates memory to the programs to be loaded

Explain - The system needs to allocate memory to the programs that need it, in order to ensure that they have sufficient space to run and store data. This allocation of memory can be done in a variety of ways, such as through virtual memory techniques that allow programs to access more memory than is physically available in the system.

In summary, both options describe important functions of the memory management system. The system must keep track of which parts of memory are in use, as well as allocate memory to programs when it becomes available. This helps ensure that programs can run smoothly and without conflicts or memory access violations.

Discipline 4 (20 questions)

Question 161

The rate at which page fault occurs is known as _______.

  1. AOption (a)

    compaction

  2. BOption (b)

    thrashing

  3. COption (c)

    paging

  4. DOption (d)

    swapping

View answer & explanation

Correct answer

Answer: (b)B.

thrashing

Why this answer is correct

The correct answer is thrashing.

Key Points

  • When the memory of the computer is exhausted too much, then the performance of the system went too low. This state of condition is known as thrashing.
  • This state of condition may lead to the page fault.
  • To avoid this condition the user needs to close a running application and reduces the size of the programs to a smaller working set. When the size of the working set is small then the rate of accuracy will increase.
  • This working set methodology optimizes the complete CPU utilization and prevents thrashing.

Thus the correct statement is t**he accuracy of the working set depends on the selection of working set size.

Additional Information

  • There are several types of thrashing techniques are there depending on the memory and storage.​
  • ​Cache thrashing: When multiples of main memory try to access the same cache memories but miss allocation in the cache, then cache thrashing has happened.
  • TLB thrashing: The full form of the TLB is Translation Lookaside Buffer. It acts as cache memory to convert virtual addresses into physical addresses. Because of this operation, the size of the working set of pages is not matching with the cache memory blocks and thrashing has happened.
  • Heap thrashing: Too much memory fragmentation is happening because the allocation of the free memory is insufficient. This kind of thrashing is known as heap thrashing.
  • Process thrashing: Process thrashing happens when all the process-working sets are not getting the free processor to run the process.

Question 162

Which of the following effects of the price change can influence the consumer’s optimal choice?

I. The change in the relative price of a good.

II. The change in the purchasing power of a consumer.

III. Sudden reduction in the minimum support price of a commodity.

  1. AOption (a)

    I and II

  2. BOption (b)

    Only III

  3. COption (c)

    I, II and III

  4. DOption (d)

    Only I

View answer & explanation

Correct answer

Answer: (a)A.

I and II

Why this answer is correct

Statement 1: CORRECT

Explanation - The change in the relative price of a good can influence the consumer’s optimal choice. A relative price change occurs when the price of one good changes relative to the price of another good. For example, if the price of coffee increases, it becomes relatively more expensive compared to tea. As a result, consumers may shift their consumption from coffee to tea, leading to a change in their optimal choice.

Statement 2: CORRECT

Explanation - The change in the purchasing power of a consumer can also influence the consumer’s optimal choice. Purchasing power refers to the ability of a consumer to buy goods and services with their income. When the price of good increases, the consumer’s purchasing power decreases. This means that the consumer can buy less of the good with their income, leading to a change in their optimal choice.

Statement 3: INCORRECT

Explanation - Sudden reduction in the minimum support price of a commodity is not directly related to the price of a good in the market. The minimum support price is the price at which the government buys crops from the farmers. A reduction in the minimum support price may affect the farmers' income and their decision to produce a particular crop. However, it does not directly affect the consumer's optimal choice.

The CRR is set by the RBI and is an important tool used by the central bank to regulate the money supply and control inflation. Banks are required to maintain the CRR on a daily average basis, and the current CRR rate is 4% of net demand and time liabilities.

Open Market Operations (OMO) - It refers to the buying and selling of government securities by the RBI in the open market to regulate the money supply and interest rates. This is done to maintain liquidity in the financial system.

Liquidity Adjustment Facility (LAF) - It is a tool used by the RBI to inject or absorb liquidity in the market through the repo rate (rate at which banks borrow from the RBI) and reverse repo rate (the rate at which banks lend to the RBI).

Statutory Liquidity Ratio (SLR) - It is the percentage of deposits that a bank is required to maintain in the form of liquid assets such as government securities, gold, or cash. The current SLR rate is 18%.

  3. COption (c)

    Rehashing

  4. DOption (d)

    Division method

View answer & explanation

Correct answer

Answer: (c)C.

Rehashing

Why this answer is correct

Explanation:

A hash function is an algorithm or a function that maps or transforms larger or longer pieces of data into a fixed or finite index or hash value.

The division method or modular hashing: 

  • The hash function is defined as h(k) = k mod m.
  • When using the division method of hash functions, we map a key k into one of the m slots by taking the remainder of k divided by m.

Folding method: 

  • It divides a key value into discrete parts that are then combined together to provide a hash value.
  • Another method is to apply a multiplicative hash function to each part separately before adding.
  • H(x) = (a + b + c) mod M, where M is the table size, a, b, and c are the three components of the preconditioned key, and mod denotes modulus.

Rehashing means hashing again, it is not used to calculate Hash functions. Hence option 3 is correct.

View answer & explanation

Correct answer

Answer: (d)D.

7

Why this answer is correct

Concept:

Page replacement algorithm: A page replacement algorithm is required in an operating system that employs paging to manage memory in order to determine which page has to be replaced when a new page is received.

First in first out (FIFO): The simplest algorithm for replacing pages is this one. The operating system maintains a queue for all of the memory pages in this method, with the oldest page at the front of the queue. The first page in the queue is chosen for removal when a page needs to be replaced.

Page fault: It is like an error. The main time it happens is when a program tries to access data or code that is in its address space but isn't now present in the system's RAM.

Explanation:

Total number of misses are 7, so page fault = 7

Important PointsBelady's anomaly: It usually occurs in FIFO. The number of page faults should typically decrease as the number of memory frames increases for obvious reasons. The phenomenon known as Belady's anomaly occurs when the number of memory frames increases together with the number of page faults.

  • the right node's value must be greater than the parent(root) node.
  • The left and right subtree each must also be a binary search tree.

Statement I is correct. If node N has no children then just replace location of N in the parent node by the null pointer.

   { } Null pointer

Statement II is incorrect because it should be, if node N has two children, then replace it by an inorder successor, not preorder. Hence option 3 is correct.

    quick fit

  4. DOption (d)

    internal fragmentation

View answer & explanation

Correct answer

Answer: (b)B.

external fragmentation

Why this answer is correct

Concept:

Fragmentation: The operating system's free memory space becomes fragmented as a result of the processes being loaded and unloaded into memory. Due to their small size, memory blocks can't be assigned to processes, hence they remain empty.

Two types of fragmentation:

  1. Internal fragmentation: When a memory block is allocated to a process, a free space is eventually created in this memory block if the process is smaller than the total amount of memory requested. And as a result, the vacant space in the memory block is unused. Internal fragmentation is brought on by this.
  2. External fragmentation: When a dynamic memory allocation mechanism allocates some memory but leaves a tiny portion of it unusable, external fragmentation occurs. Too much external fragmentation drastically reduces the amount of RAM that is available. There is sufficient RAM available, but it is not contiguous. External fragmentation is the term for it. From the above question,

two non-continuous free partition of size ‘a’ and ‘b’ are available. A process of size ‘c’ cannot be allocated even when a + b > =c, a < c and b < c.This problem is known as external fragmentation. Hence option 2 is correct.

View answer & explanation

Correct answer

Answer: (b)B.

I, II and III

Why this answer is correct

Key Points

Methods to measure the aggregate value of goods and services produced in an economy:

Expenditure method:

  • This method calculates the total value of goods and services produced in an economy by adding up all the expenditures made on final goods and services.
  • This includes consumption expenditure, investment expenditure, government expenditure, and net exports.

Income method:

  • This method calculates the total value of goods and services produced in an economy by adding up all the incomes earned by the factors of production (labor, capital and land) in the production process.
  • This includes wages and salaries, profits, interest, and rent.

Product method:

  • This method calculates the total value of goods and services produced in an economy by adding up the value added at each stage of production.
  • This means adding the value of all the goods and services produced at each stage, minus the value of intermediate goods and services used in the production process.

Hence, all three methods are used to measure gross domestic product (GDP), which is the most commonly used measure of an economy's output.

View answer & explanation

Correct answer

Answer: (b)B.

Neither I nor II

Why this answer is correct

Statement I is not correct, It should be every value in the left subtree of node is less than the value at parent node N ( left subtree value < parent node N).

Statement I is not correct, It should be every value in the right subtree of node is greater than or equal to the value at parent node N ( left subtree value >= parent node N). Hence, option 2 is correct.

Concept:

Tree: The tree is a non-linear data structure that is used to represent the data in a hierarchical form. It is a collection of nodes such that each node of the tree stores a value and a list of references to the child node.

Binary search tree(BST): A binary search tree arranges the components in a certain order. It includes some properties,

  • The left node's value in a binary search tree must be less than the parent node's value, and
  • the right node's value must be greater than the parent node.
  • Recursively, this rule is applied to the root's left and right subtrees which means the left and right subtree each must also be a binary search tree.

Correct answer

Answer: (a)A.

5

Why this answer is correct

  • Lagrange's interpolation formula can be used to find the value of a function f(x) at a point x = c, given some values of the function at other points.
  • If we have two points (x0, y0) and (x1, y1), then the formula for the interpolation polynomial is: P(x)=y0×[x−x1x0−x1]+y1×[x−x0x1−x0]P(x) = y_0 \times [\frac{x-x_1}{x_0 - x_1}] + y_1 \times [\frac{x-x_0}{x_1 - x_0}]
  • To use this formula to find the value of f(3), we need to find two points (x0, y0) and (x1, y1) such that x0 = 1, y0 = 4, x1 = 5 and y1 = 6.
  • Then we can substitute these values into the formula to get: P(x)=4×[3−51−5]+6×[3−15−1]P(x) = 4 \times [\frac{3-5}{1 - 5}] + 6 \times [\frac{3-1}{5 - 1}]
  • Simplifying this expression, we get - P(3) = 2 + 3 = 5
  • Therefore, the value of f(3) using Lagrange's interpolation is 5.

  2. BOption (b)

    0.7

  3. COption (c)

    0.8

  4. DOption (d)

    0.4

View answer & explanation

Correct answer

Answer: (a)A.

0.6

Why this answer is correct

The probability that at least one of the students P, Q, and R solves the problem is the complement of the probability that none of them solves it.

The probability that P does not solve the problem is 1 - 1/3 = 2/3

The probability that Q does not solve the problem is 1 - 1/4 = 3/4

The probability that R does not solve the problem is 1 - 1/5 = 4/5

So, the probability that none of the students solve the problem is the product of these probabilities:

P(None Solve)=23×34×45=2460=25P(\text{None Solve}) = \frac{2}{3} \times \frac{3}{4} \times \frac{4}{5} = \frac{24}{60} = \frac{2}{5}

Therefore, the probability that at least one of the students solves the problem is:

P(At Least One Solves)=1−P(None Solve)=1−25=35P(\text{At Least One Solves}) = 1 - P(\text{None Solve}) = 1 - \frac{2}{5} = \frac{3}{5}

Hence, the probability that the problem will be solved by at least one of the students is 35\frac{3}{5} = 0.6.

Key Points

  • The screen resolution is referred to as how many distinct pixels are placed horizontally and vertically on the screen of digital television, computer screen or any kind of display device.
  • The screen resolution is depending on different factors in cathode ray tube (CRT) displays, and flat-panel displays (including liquid-crystal displays). By using fixed picture-element (pixel) arrays, projection displays can be controlled.
  • The screen resolution can be calculated by multiplying the width and the height of the screen. For example, if it is provided 1024 × 768, then it means the width of the screen is 1024 pixels and the height of the screen is 768 pixels

Question 188

    Both Master Nodes

View answer & explanation

Correct answer

Answer: (a)A.

Worker Node and Master Node respectively

Why this answer is correct

The correct answer is option 1

Key Points

The main difference between NameNode and DataNode in Hadoop is that the NameNode is the master node in Hadoop Distributed File System (HDFS) that manages the file system metadata while the DataNode is a slave node in Hadoop distributed file system that stores the actual data as instructed by the NameNode.

Additional Information

  • NameNode stores the metadata of all files in HDFS. Metadata includes file permission, names, and location of each block. Namenode maps these blocks to DataNodes.
  • The data nodes store and retrieve blocks as instructed by the NameNode.

Question 190

Which is not a feature of a GUI that makes learning a program easy for users ?

  1. AOption (a)

    WYSIWYG formatting

  2. BOption (b)

    Dialog boxes

  3. COption (c)

    Detailed key strokes and commands

  4. DOption (d)

    Icons

View answer & explanation

Correct answer

Answer: (c)C.

Detailed key strokes and commands

Why this answer is correct

Concept:

GUI stands for Graphical User Interface, which is a user interface for a graphics-based operating system that facilitates interaction with the system through the use of icons, menus, and a mouse (to click on the icon or drag down the menus, respectively).

Explanation:

Features of GUI:-

  • A pointing device, such as a mouse joystick, enables the user to identify and select the appropriate commands by moving the cursor to a specific position on the screen.
  • Before and after the manipulation, the thing being manipulated is still visible on the screen.
  • WYSIWYG What You See Is What You Get indicates that a printed document is an exact replica of what is displayed on the computer screen.
  • Depending on the application, a GUI gives the appropriate messages and data on a periodic basis.
  • The characteristic of reversal is the capacity to revert to the previous action state. Icons indicate folders and applications.
  • The user can tell the computer what to do and how to accomplish it using dialogue boxes, sliders, and checkboxes.
  • Using graphical animation, a graphical representation of the current action informs the user of the current action and how to interrupt it.

Hence the detailed keystrokes and commands are not a feature of a GUI that makes learning a program easy for users.

Answer: (c)C.

Both I and II

Why this answer is correct

Women empowerment simply means providing equal opportunities to women for increasing their participation in various wakes of social life. Women empowerment aims to empower women to an extent to which they can independently take resistance of their life including education, health, Lifestyle career, etc.

Key PointsEmpowerment is a process which relates to the power of an individual to redefine her possibilities or options and to have the ability to act upon them (Eyben et al., 2008).

  • Women Empowerment refers to increasing and improving the social, economic, political and legal strength of the women, to ensure equal-right to women, and to make them confident enough to claim their rights, such as: freely live their life with a sense of self-worth, respect and dignity, have complete control of their life, both within and outside of their home and workplace.
  • Social empowerment is the most important dimension of women’s empowerment as it forms the base on which all other dimensions of women empowerment rests. Women have faced social inequalities the world over in general and in India in particular for a long time. Participation in social change is the indicator of empowered women.
  • Having the power to make independent decisions regarding all the above aspects will be an instrumental way to give social empowerment to women.
  • Participation in developmental process is also a indicator of the women empowered. When we take any developmental decision we should take the opinion of women to give empowerment to women.

​Hence, we can conclude that both I and II are the indicators of empowered women.

Question 192

_______ is the key process of teacher-centered approach.

I. Memorizing

II. Recalling from memory

  1. AOption (a)

    Only I

  2. BOption (b)

    Both I and II

  3. COption (c)

    Neither I nor II

  4. DOption (d)

    Only II

View answer & explanation

Correct answer

Answer: (b)B.

Both I and II

Why this answer is correct

The teacher is the dominant factor in all classroom activities. Everything that is done in the class, beginning from the sitting arrangements, fixing what and when to teach, maintaining discipline, asking questions, and the time and type of student evaluation is to be determined by the teacher.

Teacher-centered approach:-

  • Teachers more often use teacher-centric methods, especially where the size of the classroom is more than fifty.
  • In teacher-centric classrooms, all the instructional activities and procedures are under the control of the teacher. Teacher plans prepare and conduct the teaching-learning process including the kind of learning experiences to be provided to learners, and activities to be carried out by the learners.
  • Though it is teacher-controlled, the teacher can bring flexibility into the classroom through learners’ participation.

Important Points

  • The major belief on which this approach rests is that the teacher knows all that a learner is required to know. Therefore, the teacher can transmit bits of knowledge and skills to the children.
  • A so-called ‘good’ student stores most of these bits of knowledge in his/her memory and reproduces them whenever it is demanded.
  • On the other hand, a ‘poor’ student lacks the capability in storing and reproducing. In other words, the processes of memorizing and recalling from memory are the two key processes of this approach.

Key Points

Characteristics of Teacher-Centered Approach:

  • Knowledge is transmitted from the teacher to the students.
  • The focus is on teaching/instructing/directing rather than on learning.
  • The content and methods of teaching are decided by the teacher targeting the average students. The needs and interests of the individual students are rarely taken into account while teaching.
  • Emphasis is given on passive listening, reading and writing, and reproducing things taught by or as directed by the teacher.
  • Students’ participation in classroom activities is dictated by the teacher. In most cases, the teacher gives little scope for debate and discussion, and sharing of ideas.
  • The teacher is mostly concerned with the completion of the course contents.
  • The teacher concentrates on the right answer.
  • Extrinsic modes of motivation like praise and repbuff, reward, and punishment are generally used by the teachers.

Thus, it is clear that  Memorizing and Recalling from memory are the key processes of the teacher-centered approach.

Correct answer

Answer: (a)A.

Neither I nor II

Why this answer is correct

Language standardization refers to the concept in which a language is considered standard for personal and commercial use. It is generally decided by the ruler of that country.

Key PointsLanguage standardization follows certain steps:

  • As a first step, the language that is called standard language is the language that had been chosen to be called the standard language from the many other existing languages of that linguistic area or society.
  • This language has a certain status in that society.
  • In the Brahmanic society, Sanskrit used to be the standard language.
  • When the Arabs ruled, Arabic became the standard language.
  • When the Iranians rule, Persian became the standard language.
  • When British rule came, English became the standard language ignoring all the hundreds of languages that existed in India at that time.
  • Now Hindi and English both are official language or standard language.

Hence, we can conclude that neither I nor II both statement are not correct.

Key PointsAny art and craft that began among the inhabitants of any region performing their art and craft work from their regional location, such as villages, small towns, or any sort of regional center, is referred to as regional art and craft. At the elementary level, regional arts and crafts helps through:

  • Regional Art and crafts are natural, joyful, and fulfilling for children and it helps in the establishment of a creative, inclusive classroom (that seeks the acceptance of all learners) where imagination and innovation are valued.
  • It helps to recognize and promote traditional and contemporary art and art pieces.
  • It provides natural opportunities for children to learn through play without feeling anxious over failure. The art is child friendly and engaging because they are natural as play.
  • It helps to sensitise the children about the pluralistic cultural legacy of India – awareness of local crafts.
  • It encourages children to develop their creativity, which is essential throughout their lives. Art helps children to express themselves and their feelings.

Hence, we can conclude that both I and II are the correct statements in the context of regional arts and crafts.

Why this answer is correct

Language is systematically organized at the level of words also. There are fixed rules about how a singular would be converted into plural or a noun to adjective. Rules are so systematic that they clearly differentiate consonant ending words from vowel ending words and also words ending with different vowel sounds.

Key Points

  • In Hindi, there are 2 or 3 and even multiple plural markers for each noun, and all are rule bound.
  • In most of the cases, there is only one number system, either in singular or in plural, for one word.
  • In Hindi, every noun can have six forms in principle if we consider form and function together.
  • Many forms may look the same but have different functions in different contexts.
  • Consider the following table and see how such a system gets exemplified in words such ‘laRkaa’ and ‘ghar’.
FunctionSingularPlural
kartaa kaarak/ Nominativegharghar
bibhakti puurv/ ElsewhereghargharoN
sambodhan/ Vocativeghar!gharo!

 

FunctionSingularPlural
kkarta/ Nominative caselaRkaalaRke
bibhakti puurv/ ElsewherelaRkelaRkoN
sambodhan/ VocativelaRke!laRko!
  • If you look at the forms, you will notice that the word ‘ghar’ for example has three forms such as – ‘ghar’, ‘gharoN’, and ‘gharo’.
  • The word ‘laRkaa’ too has four forms such as – ‘laRkaa’, ‘laRke’, laRkoN’ and ‘laRko’.
  • But at the level of usage they have six forms or case based positions. In those six case positions the word ‘laRkaa’ looks like the following:
  • laRkaa khel rahaa hai
  • laRke khel rahe haiN
  • laRke ne khaanaa khaaya
  • laRkon ne khaanaa khaayaa
  • O laRke, idhar aa
  • O laRko , idhar aao !

Hence, we can conclude that in Hindi, every noun can have six forms in principle if we consider form and function together.

Both I and II

Why this answer is correct

Assessment is a process of collecting, receiving, and using data for the purpose of improvement in the learning process. It is one of the crucial components of the teaching-learning process. Assessment does more than just measure learning. There are two main types of assessments which include 'summative' and 'formative' assessments.

Key PointsFormative and Summative both are the type of the assessment.

  • Formative assessment: Formative assessment helps in providing qualitative feedback to learners to improve as It refers to monitoring learners' progress throughout the teaching-learning process to diagnose learners' learning difficulties. Oral testing, anecdotal records, portfolios, class test, etc. are the tools of formative assessment. It also provides feedback to the teachers regarding the effectiveness of their teaching.
  • Summative assessment: Summative assessment  is a type of assessment that measures, certifies, and reports the level of students' learning by assessing them at the end of the term or year. It makes judgments about the learner's skills in a specific period of time and ‘Sums-up’ how much a student has learned over a period of time. It is considered a Formal method of Assessment as it is conducted at a specific time. Example: Term-end exam, Written tests, Unit tests, Final projects, etc.

Hence, we can conclude that both formative and summative are the type of assessment.

Correct answer

Answer: (c)C.

I, II and III

Why this answer is correct

Social differences and stratifications are prominently observed the way we use language. Sometimes the people of different castes use different styles of the same language.

Key Points

  • Our choice of words, our selection of sentences are always dependent on the factors such as, the context, the person who speaks to, the place where we speak and the theme.
  • We don’t speak to our father about our school work the same way as we speak to your mom about our food etc. Also, we cannot use the same language with our teachers the language we use with our friends.
  • The moment you open your mouth you disclose your identity, Where you come from, what kind of family you belong to and what sort of people from your friend circle gets know the moment you say even a small word such as ‘hello’.
  • In Delhi, some people say ‘majja’ and others say ‘mazza’; some say ‘zafar’ and some say ‘jafar’.
  • The way of talking can tell whether the speaker is educated or uneducated, poor or rich or old Delhi or new Delhi and the like. Whether you are calling your school ‘skul’ or ‘sakul’ that too makes a lot of difference. This way linguistic identity is directly related to social identity.

Hence, we can conclude that I, II and III all are various factors on which our choice of words, our selection of sentences are always dependent.

View answer & explanation

Correct answer

Answer: (c)C.

Both I and II

Why this answer is correct

Gender discrimination refers to the unfair or unfavorable treatment of a person or a group of people based on their gender. Gender discrimination is discrimination or unequal treatment on the basis of sex.

Key PointsGender discrimination can be direct or indirect.

  • Direct discrimination occurs when gender is used as an explicit reason for discriminating. For example, a teacher wants to select a class monitor. Here, a teacher may think that it is better to have a boy as a class monitor and select a boy rather than a girl. This is direct discrimination.
  • Indirect discrimination occurs when there are provisions and practices which put girls and women at a disadvantage. For example, if an employer gets new chairs for only the male workers, it is indirect gender discrimination.

Hence, we can conclude that gender discrimination can be direct or indirect.

Important PointsSources and forms of Gender Discrimination: Gender discrimination can originate from several sources.

  • It begins with Family and parents
  • Educational opportunities
  • Nutrition, Health, and Leisure
  • Laws and rules
  • Appointment, promotion, placement
  • Division of labor inside the house
  • Education, Textbooks, Curriculum, and teachers
  • Property, Resources, and Control over resources
  • Government policies

Both I and II

Why this answer is correct

The role of a teacher at various situations. A teacher has to fulfill the expectations of the family, school, society as well as nation.

Key Points

  • The main responsibility of a teacher in the classroom is to ensure that goals of education are attained.
  • These can be specified as learning in terms of predetermined knowledge, skills, and attitudes in specific subjects.
  • In order to achieve this, a teacher creates an artificial environment (to provide educational experiences) in the classroom for facilitating the learning of learners.
  • A teacher must collect a sufficient amount of evidence to make his decisions.
  • The teacher should use content as a medium or tool not only to enable learners to acquire knowledge, skills, and attitudes but also to help them in the all-around development of their personality, which is what education stands for.
  • A teacher will need to be sensitive to the challenges some students may face in completing the tasks.

Hence, we can conclude that in the given situation both I and II statements are the aspect(s) that require a teacher's attention.

Question 200

    Only II

  3. COption (c)

    Both I and II 

  4. DOption (d)

    Neither I nor II

View answer & explanation

Correct answer

Answer: (d)D.

Neither I nor II

Why this answer is correct

The material displayed in the language classroom works to make the teaching process simple, and easy by using sense organs in teaching-learning. The use of auxiliary material should be according to the ability and qualification of the students, because if the material displayed in the language classes is not used for reading and writing, then it becomes a mere decorative item.

Key Points

Importance of material displayed in language classes-

  • Helpful in creating a language-rich environment
  • Helps to perpetuate experiences using maximum sense organs
  • Helpful in making the teaching process simple, easy, and interesting
  • Contributes to the inclusion of all children together
  • essential for effective self-learning

Both the above statements are true, but in the question, we have to choose the option which is not true. Hence, it is concluded that neither option I nor II is correct.

Hint

  • Multigrade and multi-level classrooms refer to classrooms that include children with multiple talents, different intellectual levels, or different abilities.
  • Children can do self-learning with the help of teaching-learning materials like language-lab.
