The correct answer is- '(A).'

Key Points 

• The error lies in Part (A) of the sentence.
• “Neither” is used in the same sentence as “nor” to show something is not true or doesn’t happen out of two or more people, actions, things, ideas, or qualities.
• Example: Neither my mother nor my father is coming.
• Therefore, the use of 'or' should be replaced by 'nor' to make it grammatically correct.
• Hence, the correct answer is '(A).'
• Correct sentence: Neither Mr. Smith nor Mrs. Jones came to the meeting.

Additional Information 

 

 

• A pronoun is a word that is used instead of a noun or noun phrase.
• Pronouns refer to either a noun that has already been mentioned or to a noun that does not need to be named specifically.
• The main possessive pronouns are mine, yours, his, hers, its, ours, and theirs.

Hinglish  

• त्रुटि वाक्य के Part (A) में है।
• “Neither” का प्रयोग उसी वाक्य में किया जाता है जैसे nor यह दिखाने के लिए कि कुछ सच नहीं है या दो या दो से अधिक लोगों, कार्यों, चीजों, विचारों या गुणों से नहीं होता है।
• Example: Neither my mother nor my father is coming.
• इसलिए वाक्य में  'or' के प्रयोग को 'nor' से बदल देना चाहिए ताकि वह व्याकरण की दृष्टि से सही हो।​

Given:

The average age of 6 brothers = 15 years

The age of youngest brother = 5 years

Formula used:

Average = sum of the ages/number of persons

Calculations:

Sum of the 6 persons = 6 × 15

⇒ 90

When the youngest brother born the sum of the remaining 6 brothers = 90 - 6 × 5

⇒ 90 - 30 = 60

Average of the group of brothers when the younger one born = 60/5

⇒ 12 years

∴ The average age of 6 members when younger one born is 12 years

Important Points

At the time of birth, the age of the newly born baby is 0

So, the average age of 6 boys = 60/6 = 10 years

But here, no such option is available in the official paper so we have to consider at the time of birth of the baby number of boys = 5

And then their average age was 60/5 = 12 years.

If both 10 & 12 are available in option, then 10 will get more priority.

विशेष:

The correct answer is 'Option 1'.

Key Points

• The reporting verb ("said" in this case) is changed to the past tense.
• Pronouns may change to reflect the perspective of the reported speech.
• Tenses may shift depending on whether the reported speech is in the present, past, or future tense.
• In this sentence, the reporting verb "said" is already in the past tense, so we don't need to change it.
• The pronoun "I" changes to "he" to reflect the perspective of the person reporting the speech.
• The verb "have forgotten" changes to "had forgotten" to shift the tense from present perfect to past perfect, indicating that the action occurred before the time of reporting.

Therefore, the correct answer is 'Option 1'.

Indirect speech: "He said that he had forgotten the combination of his safe."

Additional Information

• Option 2 is inappropriate and grammatically incorrect.
• Option 3 is inappropriate and grammatically incorrect.
• Option 4 is inappropriate and grammatically incorrect.

Given:

Principal of Ram = Rs. 8000

Rate of interest (For Ram) = 12%

Principal of Sham = Rs. 9100 

Rate of interest (For Sham) = 10%

Amount of Ram and Sham are equal

Formula used:

SI (= \frac{{{\rm{P;}} \times {\rm{;R;}} \times {\rm{;T}}}}{{100}})

Amount = P + S.I.

Calculation:

Let the required time be y years.

Amount of Ram = Amount of Sham

8000 + [8000 × (12/100) × y] = 9100 + [9100 × (10/100) × y]

⇒ 8000 + 960 y = 9100 + 910 y

⇒ 960 y - 910 y = 9100 - 8000

⇒ 50 y = 1100

⇒ y = 22 years

∴ The time taken to debt become equal is 22 years

The Correct answer is the Oxidation of carbon dioxide to carbohydrates.

Explanation:

• Photosynthesis is the process by which green plants prepare their own food. The events during photosynthesis are:
• 1. Absorption of light energy by chlorophyll.
• 2. Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
• 3. Reduction of carbon dioxide into carbohydrates.
• Photosynthesis is the process through which green plants synthesize or prepare carbohydrates or food from sunlight, carbon dioxide (CO2), and water.
• Photosynthesis is a reduction process that involves the reduction of carbon dioxide to carbohydrates.
• In the presence of light, green plants fix carbon dioxide to complex molecules like carbohydrates.
• Photosynthesis occurs in the chloroplast of the cell.
• Chlorophyll is a green pigment that is found in the leaves of plants.
• It helps plants to absorb sunlight energy.
• This energy is used to prepare food by combining carbon dioxide and water.
• Plants with chlorophyll pigments may perform photosynthesis by absorbing light energy.
• The conversion of light energy to chemical energy occurs during the photosynthesis process.
• The splitting of water molecules into hydrogen and oxygen is known as photooxidation.

The Utsav Bhoj Scheme incorporates several concepts that are essential to increase public participation in the mid-day meal programme.

Key Points  It was initially launched as The Bal Jivaan Yojana and went into effect on May 9, 2008. This scheme is now known as Utsav Bhoj.

• The Rajasthan government initiated this programme as an extension of the central government's midday meal programme, under which individuals in the community can offer food to children if they so desire.
• According to the circular, during the scheme's execution, the donor institution may provide food, utensils, gas stoves, carpets, and other materials to the school as required. Aside from that, a kitchen, toilet, water tank, and so on can be built in the school as needed.
• The school administration committee or the person in charge of the mid-day meal would examine the food to ensure that it is fresh and edible before delivering it to the children.

Thus, it can be inferred that the “UTSAV BHOJ” Yojana is the extension of Mid day meal scheme (MDM) of the central government by the Rajasthan government.

Shortcut Trick

Required number = LCM (10, 14, 12, 8) + Common Remainder

Prime factors of 10, 14, 12, 8 are used to find LCM.

LCM (10, 14, 12, 8) = 840

Required number = 840 + 7 = 847

∴ The correct answer is 847.

Alternate Method

Given: Divisors are 10, 14, 12, and 8. The remainder in each case is 7.

Formula Used: The least number which when divided by x, y, and z leaves the same remainder 'r' is (LCM of x, y, z) + r.

Step 1: Find the Prime Factorization of the given numbers:

⇒ 10 = 2 × 5

⇒ 14 = 2 × 7

⇒ 12 = 2² × 3

⇒ 8 = 2³

Step 2: Calculate the LCM (highest power of each factor):

⇒ LCM = 2³ × 3 × 5 × 7

⇒ LCM = 8 × 3 × 5 × 7 = 840

Step 3: Add the constant remainder to the LCM:

⇒ Required number = 840 + 7

⇒ Required number = 847

∴ The correct answer is 847.

Additional Information

LCM Property for Same Remainder

When a number leaves the same remainder r when divided by a, b, and c, the general form is N = k × LCM(a, b, c) + r, where k is an integer.

LCM Property for Different Remainders

If divisors are a, b, c and remainders are r₁, r₂, r₃ such that (a−r₁) = (b−r₂) = (c−r₃) = k, then the number is LCM(a, b, c) − k.

HCF vs LCM

HCF is the largest number that divides the given numbers, while LCM is the smallest number divisible by the given numbers.

Here, the erroneous part is "in such short notice."

Key Points 

• The error lies in the part "in such short notice" of the sentence.
• The meaning of the idiom "on short notice" is only a short time before something happens.
• Example: I can't cancel my plans on such short notice.
• ​Hence, in the given sentence 'in' will be replaced by 'on' to make the sentence grammatically correct.
• Therefore, the correct answer is Option 3.

Correct sentence- It will be difficult to arrange payment on such short notice.

Given:

2x + 3y = 14 and xy = 8

Concept used:

(a + b)² = a² + b² + 2ab

a³ + b³ = (a + b)(a² - ab + b²)

Calculation:

2x + 3y = 14

on squaring both side we get

(2x + 3y)² = 14²

⇒ 4x² + 9y² + 12xy = 196

⇒ 4x² + 9y² + 12 × 8 = 196

⇒ 4x² + 9y² = 100

now,

8x³ + 27y³ = (2x)³ + (3y)³

⇒ (2x)³ + (3y)³ = (2x + 3y)(4x² - 6xy + 9y²)

⇒ (2x)³ + (3y)³ = 14 × (100 - 6 × 8)

⇒ 14 × 52 = 728

∴ The answer is 728.

Alternate Method a3 + b3 = (a + b)3 - 3ab(a + b

8x3 + 27y3 = (2x + 3y)3 - 3 × 2x × 3y(2x + 3y)

⇒ 14³ - 18 × 8 × 14

⇒ 2744 - 2016

⇒ 728

∴ The answer is 728.

CONCEPT:

• Solenoid: A cylindrical coil of many tightly wound turns of insulated wire with a general diameter of the coil smaller than its length is called a solenoid.

Given:

Diameter of the cone = 56 metres, so radius (r) = 56 / 2 = 28 metres

Slant height (l) = 35 metres

Formula used:

Volume of the cone = (\dfrac{1}{3} \pi r^2 h), where h is the height of the cone.

Calculation:

To find the height (h) of the cone, we use the Pythagorean theorem:

l² = r² + h²

35² = 28² + h²

1225 = 784 + h²

h² = 1225 - 784

h² = 441

h = √441 = 21 metres

Volume = (\dfrac{1}{3} × \frac{22}{7} × 28^2 × 21)

Volume = 22 × 28 × 28

Volume = 17248 cubic metres

Therefore, the volume of the cone is 17,248 cubic metres .

Shortcut Trick

Since time period is same (5 years), Profit Ratio = Investment Ratio.

Ratio of A : B = 36,000 : 58,000 = 18 : 29.

Total units = 18 + 29 = 47 units.

47 units = ₹94,000 → 1 unit = ₹2,000.

B's share = 29 units = 29 × 2,000 = ₹58,000.

∴ The correct answer is ₹58,000.

Alternate Method

Given:

Investment of A = ₹36,000

Investment of B = ₹58,000

Time period = 5 years

Total Profit = ₹94,000

Formula Used:

Profit Share Ratio = (Investment_A × Time_A) : (Investment_B × Time_B)

A: ₹36,000 18 units

B: ₹58,000 29 units

Total Ratio: 47 Profit: ₹94k

Calculations:

⇒ Profit Ratio A : B = (36000 × 5) : (58000 × 5)

⇒ Profit Ratio A : B = 36 : 58 = 18 : 29

⇒ Sum of ratio parts = 18 + 29 = 47

⇒ Total Profit = ₹94,000

⇒ B's Share = (29 ÷ 47) × 94,000

⇒ B's Share = 29 × 2,000

⇒ B's Share = ₹58,000

∴ The correct answer is ₹58,000.

Additional Information

Basic Partnership Law

Profit is always distributed in the ratio of the product of capital and the time for which it was invested (P = C × T).

Case of Equal Time

When the time period for all partners is identical, the profit sharing ratio is exactly the same as the investment ratio (P₁ : P₂ = C₁ : C₂).

Working vs Sleeping Partner

A working partner manages the business and may receive a fixed salary or commission before the remaining profit is divided according to investment ratios.

The correct answer is rise a little higher.

Key Points

• Buoyant force
• ​The buoyant force is an upward force on an object that is wholly or partially immersed in a fluid.
• Due to the force of buoyancy, a body partially or wholly immersed in a liquid tends to lose its weight, that is, it appears to be lighter.
• Sea water is denser than river water.
• A ship experiences more buoyant force in seawater than in river and hence the volume of the ship submerged in water decreases to balance the weight of the ship.
• In Sea water density is higher than river water that's why a ship experiences more buoyant force in sea water.
• So when it goes from the river to the sea it ​rises a little higher.

• So, grammatically, "an" is appropriate in this context to ensure proper usage of the indefinite article before the adjective "exhaustive." Thus, option 2, "an," is indeed the correct choice.
  

Correct Sentence: This is not an exhaustive list of words.

Concept used:

Twin Prime Number: It is the set of two numbers that have exactly one composite number between them. They can also be defined as pairs of prime numbers that have a difference of 2.

For example, (3, 5), (11, 13), and (17, 19) are examples of twin prime pairs.

Calculation:

The prime numbers between 51 and 100 are;

53, 59, 61, 67, 71, 73, 79, 83, 89, 97

Now, look for the twin prime numbers in the above numbers,

(59, 61) and (71, 73)

Hence, there are two twin prime numbers between 51 and 100.

Explanation:

• The light incident on a reflecting surface is not reflected entirely, some portion of the light is reflected while some portion of the light is absorbed by the surface.
• The ratio of reflected light to incident light is called the reflection factor.

Shortcut Trick

Initial ratio of CP : SP = 100 : 120 = 5 : 6

New ratio of CP : SP = 100 : 140 = 5 : 7 (since both CP and SP are reduced by ₹20)

Applying the cross-multiplication method: Difference in ratio units = (5 × 7) − (5 × 6) = 5 units.

Absolute difference in value = (7 × 20) − (5 × 20) = 40.

⇒ 5 units = ₹40 (Since initial CP is exactly 5 units, Initial CP = ₹40).

∴ The correct answer is ₹40.

Alternate Method

Given:

Initial profit = 20%

Both Cost Price (CP) and Selling Price (SP) are reduced by ₹20.

New profit = 40%

Formula Used:

SP = CP × (100 + Profit%) ÷ 100

Initial Scenario

CP = 5x

+20% Profit

SP = 6x

− ₹20

− ₹20

New Scenario

CP = 5x − 20

+40% Profit

SP = 6x − 20

Equation: (6x − 20) = 1.4 × (5x − 20)

Calculations:

Let the initial Cost Price (CP) be 5x and Selling Price (SP) be 6x (from the 20% profit ratio of 100:120).

⇒ New CP = 5x − 20

⇒ New SP = 6x − 20

The new profit is 40%, so the ratio of new CP to new SP is 100 : 140 = 5 : 7.

⇒ (5x − 20) ÷ (6x − 20) = 5 ÷ 7

⇒ 7 × (5x − 20) = 5 × (6x − 20)

⇒ 35x − 140 = 30x − 100

⇒ 35x − 30x = 140 − 100

⇒ 5x = 40

⇒ Initial Cost Price = 5x = ₹40.

∴ The correct answer is ₹40.

Additional Information

Profit and Loss Ratios

Profit or loss is always calculated on the base of Cost Price (CP) unless specifically mentioned otherwise. Profit % = (SP − CP) ÷ CP × 100.

Cross Multiplication Method

When two related quantities (like CP and SP) change by equal or unequal amounts, their final ratio can be determined smoothly using cross-product differences directly equated to the absolute magnitude of change.

Marked Price and Discount

Discount is exclusively given on the Marked Price (MP). The relationship connecting Cost Price, Marked Price, Profit% and Discount% is MP ÷ CP = (100 + Profit%) ÷ (100 − Discount%).

Investment Ratio = Profit Ratio ÷ Time Ratio

Investment Ratio = (4 ÷ 3) : (3 ÷ 2) : (14 ÷ 7)

Investment Ratio = 4/3 : 3/2 : 2

Multiply the entire ratio by the LCM of denominators (3 and 2), which is 6.

Investment Ratio = (4/3 × 6) : (3/2 × 6) : (2 × 6) = 8 : 9 : 12

∴ The correct answer is 8 : 9 : 12.

Alternate Method

Given:

Ratio of Time Periods (T_A : T_B : T_C) = 3 : 2 : 7

Ratio of Profits (P_A : P_B : P_C) = 4 : 3 : 14

Formula Used:

Profit = Investment × Time ⇒ Investment = Profit ÷ Time

Calculations:

⇒ Let Investment of A, B and C be I_A, I_B and I_C respectively.

⇒ I_A : I_B : I_C = (P_A / T_A) : (P_B / T_B) : (P_C / T_C)

⇒ I_A : I_B : I_C = (4/3) : (3/2) : (14/7)

⇒ I_A : I_B : I_C = (4/3) : (3/2) : 2

⇒ To remove fractions, multiply by LCM of 3 and 2 = 6

⇒ I_A : I_B : I_C = (4/3 × 6) : (3/2 × 6) : (2 × 6)

⇒ I_A : I_B : I_C = 8 : 9 : 12

∴ The correct answer is 8 : 9 : 12.

Given:

x and y are two positive numbers such that when x is reduced by 2 and y is increased by 2 , the ratio becomes 2 ∶ 1; and when x is increased by 2 and y is reduced by 2 , the ratio becomes 3 ∶ 1.

Calculation:

According to the question,

⇒ (\dfrac{x-2}{y+2} = \dfrac{2}{1})    

⇒ x - 2 = 2y + 4

⇒ x = 2y + 6       →   (1)

⇒ (\dfrac{x+2}{y-2} = \dfrac{3}{1})   

⇒ x + 2 = 3y - 6

⇒ x = 3y - 8   →   (2)

On putting the value of x from eq(1) in eq(2),

⇒ 2y + 6 = 3y - 8

⇒ y = 14

⇒ x = 2(14) + 6 = 34

⇒ x - y = 34 - 14 = 20

∴ x - y = 20

Concept used:

Follow the BODMAS rule according to the table given below: 

Calculation:

⇒ (\left[{\frac{1}{5} + \left(\frac{9}{15} \times \frac{7}{5} \right) - \left( \frac{4}{5} \times \frac{6}{9}\right) + \frac{3}{4}} \right] ) of (\frac{2}{3})

⇒ (\left[{\frac{60 + 252 - 160 + 225}{300}} \right] \times \frac{2}{3} )

⇒ (\left[{\frac{377}{300}} \right] \times \frac{2}{3} )

⇒ (\frac{377}{450})

∴ (\left[{\frac{1}{5} + \left(\frac{9}{15} × \frac{7}{5} \right) - \left( \frac{4}{5} × \frac{6}{9}\right) + \frac{3}{4}} \right] × \frac{2}{3} = \frac{377}{450} )

The correct answer is Velocity.

CONCEPT:

• Velocity: The rate of change of displacement of a body is called the velocity of that body.
• Velocity is a vector quantity that has both magnitudes as well as direction.
• Acceleration: The rate of change of velocity is called the acceleration of the body.
• Acceleration is also a vector quantity.
• Retardation/Negative acceleration: When the acceleration of the body is in the opposite direction of the velocity is called deceleration.
• It is a negative acceleration of the body.

EXPLANATION:

• The direction of acceleration is determined by the general principle that if an object is slowing down, the acceleration is in the opposite direction of the motion.
• Therefore, from this principle, it becomes clear that when an object is slowing down, the acceleration is in the opposite direction of velocity. This is a negative acceleration. So option 1 is correct.

The correct answer is Assam.

Given:

A can beat B by 50 m in a race of 500m.

B can beat C by 60 m in a race of 600m.

Concept used:

If A is at 500 m then 

B = 500 - 50

B = 450m

A : B = 500 : 450

         = 10 : 9            {i}

In race of 600 m 

If B is at 600m then

C = 600 - 60

C = 540

B : C = 600 :540

         = 10 : 9            {ii}

Calculations:

 Now keeping the ratio of B constant  in both equations {i} and {ii}

  A : B = (10 : 9 ) × 40

          =  400 : 360

  B : C = (10 : 9)  × 36

           = 360 : 324

 Now,

 A : B : C = 400 : 360 : 324

 A will beats C by

 400 - 324 = 76

∴ A beat C by 76 m  in race of 400 m.

The correct answer is: that happens in nature.

Key Points

• The original sentence is grammatically incorrect because ""natures"" should be singular ""nature"". Option 4 corrects this error by using the singular form ""nature"" and the correct verb tense ""happens"".
• Option 1 is incorrect because ""happening"" is a gerund and cannot be used as the subject of the sentence.
• Option 2 is incorrect because ""natures"" is still plural and the incorrect verb tense ""happens"" is used.
• Option 3 is incorrect because the original sentence contains a grammatical error.

Hence, the corrected form of the sentence is: Not everything that happens in nature is due to global warming alone.

Given:

53x ÷ 54x = (\sqrt[4]{5}^{16})

Calculation:

53x ÷ 54x = (\sqrt[4]{5}^{16})

⇒ x = -4

∴ The value of x is -4.

The correct answer is Violet and Red.

Key Points

• White light comprises all colors of the VIBGYOR i.e. Violet, Indigo, Blue, Green, Yellow, Orange, Red.
• When we optically combine these colors we get white light.
• The wavelength of light defines the color of the light and in VIBGYOR, wavelength increases from left to right.
• That means Violet color has minimum wavelength while Red color has a maximum wavelength.
• Prism is a triangular slab of transparent glass through which light can pass.
• But before going into prism we must remember that when light passes from one medium to another, it undergoes refraction.
• Refraction is the phenomenon of bending of light when it travels from one medium to another.
• Now the amount of bending of light depends on the wavelength of light.
• The smaller the wavelength of light, the greater is its bending when it passes from one medium to another.
• That is, we can say that the amount of bending of light is inversely proportional to the wavelength of light.
• This property of light leads to the splitting of different colors of light when passed through a prism as shown in the figure.
• Violet bends the most because it has a shorter wavelength compared to other colors and the red color bends the least and can be seen at the end opposite to the base of the prism. Hence, Option 4 is correct.

Shortcut Trick

Ratio of Mohan to Brother present age = 2 : 1 (Difference = 1 unit)

Ratio 3 years ago = 3 : 1 (Difference = 2 units)

Equating differences: Present ratio becomes 4 : 2. Difference between 4 and 3 is 1 unit.

1 unit → 3 years.

Mohan's present age = 4 units = 4 × 3 = 12 years.

∴ The correct answer is 12 years.

Alternate Method

Let the present age of Mohan's brother be x years.

⇒ Mohan's present age = 2x years.

⇒ 3 years ago, Brother's age = x − 3

⇒ 3 years ago, Mohan's age = 2x − 3

According to the question:

⇒ 2x − 3 = 3 × (x − 3)

⇒ 2x − 3 = 3x − 9

⇒ 3x − 2x = 9 − 3

⇒ x = 6

⇒ Mohan's present age = 2 × 6 = 12 years.

∴ The correct answer is 12 years.

Additional Information

Age Difference Property

The difference between the ages of two people remains constant regardless of the number of years passed or preceding.

Ratio Balancing

To solve age problems using ratios, multiply the ratios such that the numerical difference between the parts of the two ratios becomes equal to the actual time gap.

The correct answer is an infectious disease 

Key Points

• An infectious disease can be defined as an illness due to a pathogen or its toxic product, which arises through transmission from an infected person, an infected animal, or a contaminated inanimate object to a susceptible host.
• Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi, or parasites.
• Some infectious diseases can be passed from person to person
• Infectious diseases commonly spread through the direct transfer of bacteria, viruses, or other germs from one person to another.
• This can happen when an individual with the bacterium or virus touches, kisses, or coughs, or sneezes on someone who isn't infected

 Important Points

• Non-infectious diseases are not caused by pathogens and therefore cannot be spread from one person to another.
• Instead, non-infectious diseases are caused by factors such as genetics, malnutrition, environment, and lifestyle.
• A chronic disease that is persistent or otherwise long-lasting in its effects or a disease that comes with time.
• The term chronic is often applied when the course of the disease lasts for more than three months
• An acute disease appears suddenly and lasts for a short amount of time.
• This is different from chronic diseases, which develop gradually and remain for months on end.
• Some examples include the influenza virus and the common cold

Given:

Votes for A = 61% of total votes 

Votes % for A - Votes % for B = 3806

Calculation:

Let, total votes = 100%

Votes for B = (100 - 61)% of total votes = 39% of total votes

According to the question,

⇒ (61 - 39)% = 3806

⇒ 22% = 3806

⇒ 1% = 3806/22

So, 100% = (\dfrac{3806\times 100}{22}) = 17300 votes

∴ Total number of votes cast is 17300.
