View answer & explanation

Correct answer

Answer: (b)B.

130

Why this answer is correct

Sum of weight of all the boxes = 20 + 40 + 50 + 30 = 140 kg

Sum of weight of two boxes having weight of 40kg and 50 kg = 40 + 50 = 90 kg

Sum of weight of three boxes having weight 40 kg, 50 kg and 30 kg = 40 + 50 + 30 = 120 kg

As we have found the possibility of three weights, hence by elimination method we can say that 130 kg weight is not possible from the given weights.

Why this answer is correct

CONCEPT:

  • Force: A force is a push or pull acting upon an object as a result of its interaction with another object.
  • A force acting for a given amount of time will change an object's momentum ( or say velocity if the mass is being constant).
  • Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity.
  • Forces cause acceleration in the body.

​EXPLANATION:

  • A force can cause an object with mass to change its velocity (which includes ​beginning moving from a state of rest), i.e., to accelerate.
  • Force can also be described intuitively as a push or a pull.

So option 3 is correct.

  4. DOption (d)

    3

View answer & explanation

Correct answer

Answer: (c)C.

4

Why this answer is correct

A, B and C take 12, 8 and 24 days respectively to finish the entire work.

Part of work done by A in 1 day = 1/12

Part of work done by B in 1 day = 1/8

And part of work done by C in 1 day = 1/24

When they work together, part of work finished by all three in one day =112+18+124= \frac{1}{{12}} + \frac{1}{8} + \frac{1}{{24}}

Let’s assume that they together can finish the entire work in x days

x(112+18+124)=1x\left( {\frac{1}{{12}} + \frac{1}{8} + \frac{1}{{24}}} \right) = 1

⇒ x ((2 + 3 + 1)/24) = 1

⇒ 6x/24 = 1

⇒ x = 4

∴ Together they’ll finish the work in 4 days

-6

Why this answer is correct

by using identity,

⇒ (a + b)3 = a3 + b3 + 3ab(a + b)

It is given that a3 + b3 = 19 and a + b = 1

Then,

13 = 19 + 3ab(1)

⇒ 3ab = -18

⇒ ab = -6

Alternative method:

Assume, a = 3 and b = -2

These values satisfied both the given conditions

 ∴ ab = 3 × (-2) = -6

    7.5

  4. DOption (d)

    15

View answer & explanation

Correct answer

Answer: (a)A.

12.5

Why this answer is correct

Concept:

  • Speed is the distance covered by an object in a given amount of time.
  • Speed is measured in Kilometers per Hour (km/hr) or meters per second (m/sec).
  • Average Speed: Since the body does not always have the same speed, So we use the concept of average speed. It is the ratio of total distance covered to total time taken by the body.
  • Average;Speed=Total;DistanceTotal;TimeAverage;Speed = \frac{{Total;Distance}}{{Total;Time}}

Calculation:

Average speed of the car = (total distance) /(total time taken)

⇒ Average speed = 144 km/3.2 hr = 45 km/hr

We know that,

  • To convert Km/hr into m/sec we multiply the speed by 5/18.
  • To convert m/sec into km/hr we multiply the speed by 18/5.

∴ Average speed (meter/second) = 45 × 5/18 = 12.5m/sec

  4. DOption (d)

    1765.2

View answer & explanation

Correct answer

Answer: (b)B.

2065.2

Why this answer is correct

let principal amount at simple interest be 100

a/q the amount become 118 in 2 years at simple interest

⇒ Simple interest = 118 - 100 = 18

So, SI = P × R × T/100

⇒ 18 = 100 × R × 2/100

⇒ R = 9%

Therefore,

CI=P(1+9100)3−P ⇒;CI=7000(1+9100)3−7000\begin{array}{l} CI = P{\left( {1 + \frac{9}{{100}}} \right)^3} - P\ \Rightarrow ;CI = 7000{\left( {1 + \frac{9}{{100}}} \right)^3} - 7000 \end{array}

⇒ CI = 7000 × 109/100 × 109/100 × 109/100 - 7000

∴ Compound interest = Rs. 2065.20

View answer & explanation

Correct answer

Answer: (a)A.

42

Why this answer is correct

Average weight of P, Q and R = 45 kg

Total weight of all together = P + Q + R = 45 × 3 = 135      ----(i)

Average weight of P and Q be 36.5 and Q and R be 52 kg

P + Q = 36.5 × 2 = 73      ----(ii)

Q + R = 52 × 2 = 104       ----(iii)

On solving eq. (i) and (ii)

Weight of R = 62

Then from eq. (iii)

⇒ Q + 62 = 104

⇒ Q = 42

∴ Weight of Q is 42 kg

Question 68

What is the reflection of the point (-2, 5) in the line x = -1?

  1. AOption (a)

    (-2, -7)

  2. BOption (b)

    (0, 5)

  3. COption (c)

    (2, 5)

  4. DOption (d)

    (-2, 7)

View answer & explanation

Correct answer

Answer: (b)B.

(0, 5)

Why this answer is correct

When a point is reflected about the y-axis, the y-coordinate remains the same and only the x-coordinate is transformed

∵ The line x = -1 is parallel to the y-axis, y-coordinate will remain the same after reflection

Now, along the x-direction, the distance between the reflected point and the line will be equal to the distance between the original point and the line

⇒ Distance between point and line along x-direction = ।-1 - (-2)। = ।1। = 1 unit

⇒ X-coordinate of reflection = -1 + 1 = 0

∴ The reflection point is (0, 5)

Question 69

ΔABC is similar to ΔPQR. If ratio of perimeter of ΔABC : perimeter of ΔPQR is 5 : 9 and if PQ = 45 cm, then the length of AB (in cm) is?

  1. AOption (a)

    15

  2. BOption (b)

    20

  3. COption (c)

    25

  4. DOption (d)

    16

View answer & explanation

Correct answer

Answer: (c)C.

25

Why this answer is correct

It is given ΔABC is similar to ΔPQR

By the property of similarity of triangles ratios of respective sides of triangles are equal

⇒ (perimeter of ΔABC) / (perimeter of ΔPQR) = AB/PQ

⇒ 5/9 = AB/45

⇒ AB = 25

Question 70

What least number must be added to 4131, so that the sum is completely divisible by 19?

  1. AOption (a)

    10

  2. BOption (b)

    11

  3. COption (c)

    9

  4. DOption (d)

    12

View answer & explanation

Correct answer

Answer: (b)B.

11

Why this answer is correct

When 4131 is divided by 19, we get 8 as the remainder

∴ Least number that must be added = 19 - 8 = 11

Alternative solution:

We have to find the multiple of 19 which is near to the number 4131 i.e. 4142

∴ Least number that must be added = 4142 - 4131 = 11

Question 71

What is the sum of the first 12 terms of an arithmetic progression if the first term is -19 and last term is 36?

  1. AOption (a)

    192

  2. BOption (b)

    230

  3. COption (c)

    102

  4. DOption (d)

    214

View answer & explanation

Correct answer

Answer: (c)C.

102

Why this answer is correct

Given: number of terms of an AP (arithmetic progression) = 12

First term = a = -19

Last term = l = 36

Sn (sun of the AP) = (no. of terms)/2 × (first term + last term)

⇒ Sn = 12/2 × (-19 + 36)

∴ Sn = 102

Question 72

Based on Passage: View directions & passage

The ratio of tickets sold by Airlines A and D to tickets sold by Airline E is?

  1. AOption (a)

    3 : 4

  2. BOption (b)

    4 : 3

  3. COption (c)

    2 : 3

  4. DOption (d)

    4 : 1

View answer & explanation

Correct answer

Answer: (b)B.

4 : 3

Why this answer is correct

Tickets sold by Airlines A and D = 5000 + 3000 = 8000

Tickets sold by airlines E = 6000

∴ Required ratio = 8000/6000 = 4/3

Question 73

Based on Passage: View directions & passage

If the price of an airline ticket is Rs. 7000 then by what amount, monthly Revenue (in Rs. Millions) from sale of tickets of Airline B is greater than that of Airline E?

  1. AOption (a)

    77

  2. BOption (b)

    7

  3. COption (c)

    35

  4. DOption (d)

    42

View answer & explanation

Correct answer

Answer: (c)C.

35

Why this answer is correct

The price of a ticket is Rs. 7000

Revenue from sale of tickets of Airline B = 11,000 × 7,000 = Rs. 77,000,000

Revenue from sale of tickets of Airline E = 6,000 × 7,000 = Rs. 42,000,000

The sale of tickets of Airline B is greater than that of Airline E = 77,000,000 - 42,000,000 = 35,000,000

∴ Monthly Revenue (in Rs. Millions) from sale of tickets of Airline B is greater than that of Airline E = Rs. 35 millions

Question 74

A fraction is greater than its reciprocal by 72/77. What is the fraction?

  1. AOption (a)

    7/11

  2. BOption (b)

    11/7

  3. COption (c)

    4/7

  4. DOption (d)

    7/4

View answer & explanation

Correct answer

Answer: (b)B.

11/7

Why this answer is correct

One thing is clear that fraction must be greater than it’s reciprocal

Now going through the option, we can easily eliminate option 1st and 3rd because its reciprocal is greater than the respective fractions

∴ Option 4th by solving

Alternative solution:

Let the friction be x

So, x - 1/x = 72/77

⇒ (x2 - 1) /x = 72/77

⇒ 77x2 - 72x - 77 =0

⇒ x = 11/7 and (-7)/11

∴ Friction = 11/7

Let say number = x/y

then reciprocal = y/x

⇒ x/y - y/x = 72/77

⇒ x2 – y2 = 72xy/77

⇒ 77x2 – 77y2 – 72xy = 0

⇒ 77x2 – 72xy – 77y2 = 0

⇒ 77x2 – 121xy + 49xy – 77y2 = 0

⇒ 11x(7x – 11y) + 7y(7x – 11y) = 0

⇒ (11x + 7y) (7x - 11y) =0

x/y = -7/11  or  11/7

Question 75

If Tan θ = 7/24, then what is the value of Sec θ?

  1. AOption (a)

    24/25

  2. BOption (b)

    24/7

  3. COption (c)

    25/7

  4. DOption (d)

    25/24

View answer & explanation

Correct answer

Answer: (d)D.

25/24

Why this answer is correct

Trigonometric ratio tan θ = (Perpendicular(p))/(base(b)) = 7/24

According to Pythagoras theorem,

Hypotenuse2 (h) = perpendicular2(p) + base2(b)

⇒ Hypotenuse2 (h) = 25

∴ Sec θ = (hypotenuse(h)) / (base(b)) = 25/24

    Conformity

  2. BOption (b)

    Surety

  3. COption (c)

    Bias

  4. DOption (d)

    Evidence

View answer & explanation

Correct answer

Answer: (c)C.

Bias

Why this answer is correct

The correct answer is option 3, 'bias'.

'Fallacy' means 'a mistaken belief, based on unsound arguments'.

'Bias' means 'an unfair and wrong inclination toward someone'.

'Conformity' means 'compliance with rules or laws, surety means the state of being certain of something and evidence means proof something'.

Therefore, out of the given options, only 'bias' has a meaning similar to 'fallacy' and is the correct answer.

Question 77

In the following question, out of the four alternatives, select the alternative which will improve the bracketed part of the sentence. In case no improvement is needed, select "no improvement".

All (was surprising) to find that he was not with them.

  1. AOption (a)

    was surprised

  2. BOption (b)

    were surprised

  3. COption (c)

    is surprised

  4. DOption (d)

    no improvement

View answer & explanation

Correct answer

Answer: (b)B.

were surprised

Why this answer is correct

The correct answer is option 2, 'were surprised'.

Due to the presence of ‘all’, we know that the sentence is in plural form and therefore, the plural form of ‘was’ must be used.

Hence, the correct answer should have ‘were’, as seen only in Option 2.

Question 78

In the following question, some parts of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'.

She was so (1)/ near to (2)/ achieving her goal. (3)/No Error (4)

  2. BOption (b)

    2

  3. COption (c)

    3

  4. DOption (d)

    4

View answer & explanation

Correct answer

Answer: (b)B.

2

Why this answer is correct

The correct answer is option 2.

‘Near’ means ‘at a short distance away or close to.

Hence, the sentence is grammatically incorrect.

A better substitute for the word ‘near’ is ‘close’, which expresses the idea of a short distance not only in physical terms but in other forms of distance as well, as is the case in the question.

Therefore, the correct sentence is: ‘She was so close to achieving her goal.’

Question 79

In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'.

He watched as fights (1)/ broke out (2)/ along the city. (3)/No Error (4)

  1. AOption (a)

    1

  2. BOption (b)

    2

  3. COption (c)

    3

  4. DOption (d)

    4

View answer & explanation

Correct answer

Answer: (c)C.

3

Why this answer is correct

The correct answer is option 3.

‘Along’ means ‘by the side of’.

The phrase ‘along the city’ makes little sense and is incorrect.

The word ‘across’ means ‘from one side to the other, covering the area’.

Hence, ‘across the city’ expresses the idea of fights breaking out all over the city.

Therefore, the correct answer is: ‘He watched as fights broke out across the city.’

View answer & explanation

Correct answer

Answer: (a)A.

The spectators applauded Jay for his good hit.

Why this answer is correct

The correct answer is option 1, 'The spectators applauded Jay for his good hit'.

Sentence 2 is incorrect as it uses ‘bravo’, even after using ‘applauded’, Sentences 3 and 4 have the present tense and incorrect words.

Only Sentence 1 changes the present tense to past tense and converts ‘bravo’ into ‘applauded’. Hence, it is the correct answer.

    ZXY

View answer & explanation

Correct answer

Answer: (b)B.

XZY

Why this answer is correct

The correct answer is option 2, 'XZY'.

The first sentence is X, since the word ‘large’ must be followed by an object which is large.

In this case, the object is ‘hut’.

Moreover, Y must come after Z since Z uses the adjective of place for the stools.

This makes XZY the correct combination, as seen in Option 2.

Question 86

In the following question, out of the four alternatives, select the alternative which is the best substitute of the words/sentence.

Showing strong feeling

  1. AOption (a)

    Meek

    ZXY

View answer & explanation

Correct answer

Answer: (b)B.

XZY

Why this answer is correct

The correct answer is option 2, 'XZY'.

The first sentence must be X, since it begins with an ‘of’, while the other sentences disrupt the flow. Also, Y should come after Z due to grammatical coherence, as YZ ends the passage abruptly. Therefore, XZY is a combination, as seen only in Option 2.

    Admiration

View answer & explanation

Correct answer

Answer: (b)B.

Contempt

Why this answer is correct

The correct answer is option 2, 'contempt'.

'Veneration' means 'great respect for something'. On the other hand, 'contempt' means 'disrespect or disregard for something'.

Hence, the two words have opposite meanings.

The other words, 'adoration', 'admiration' and 'reverence' are synonymous with 'veneration'.

Question 94

In the following question, four words are given out of which one word is correctly spelt. Select the correctly spelt word.

Hence, the two words have similar meanings.

'To commend' and 'to laud' mean 'to praise someone highly or officially' and 'to exonerate' means 'to acquit someone from a fault'.

Question 96

In the following question, the sentence is given with blank to be filled in with an appropriate word. Select the alternative out of the four and indicate it by selecting the appropriate option.

  3. COption (c)

    very much

  4. DOption (d)

    far

View answer & explanation

Correct answer

Answer: (d)D.

far

Why this answer is correct

The correct answer is 'Option 4' i.e. 'Far'.

Key Points

  • The correct answer is "far".
  • In this context, the adjective "far" is used to indicate a high degree of something, and it's usually paired with another adjective.
  • So, the phrase "far too extravagant" means that the diamond necklace is excessively or extremely extravagant.

Therefore, the sentence would read: "The diamond necklace was far too extravagant for a simple dinner party." 

Additional Information

  • Here is why the other options are incorrect:
  • "Distance" is a noun that refers to the amount of space between two points, and it does not fit in this context.
  • "Long" is typically used to describe length or duration, not the degree of extravagance.
  • "Very much" is typically used with verbs or as a response to a question about the degree of something, not as a modifier for an adjective like "extravagant".
