View answer & explanation

Correct answer

Answer: (b)B.

as she always have time to listen and guide

Why this answer is correct

The correct answer is option 2) i.e., 'as she always have time to listen and guide'.

Key Points

  • The error lies in the part as she always have time to listen and guide.
  • The given sentence is in past tense as it talks about the time when the subject was in school. (was, found are past tense verbs)
  • But in option 3 the present tense verb have has been used.
  • This makes as she always have time to listen and guide the incorrect part.
  • Thus, option 3 is the correct answer.

So the correct sentence is- When I was at school I found my class teacher to be the best mentor as she always had time to listen and guide.

Additional Information

  • We can correct the part as she always have time to listen and guide by using had instead of have.

View answer & explanation

Correct answer

The correct answer is option 2) i.e., 'a difficult person or problem'. 

Key Points

  • Hard nut to crack is an idiomatic expression that means a person or thing that is difficult to deal with, understand, or influence (का अर्थ है एक व्यक्ति या वस्तु जिससे निपटना, समझना या प्रभावित करना मुश्किल हो)
  • *The problem is a **hard nut to crack.***​
  • This means that option 2 - a difficult person or problem is the most appropriate meaning of the given idiom.

was engaged

Why this answer is correct

The correct answer is option 3) i.e., 'was engaged'.

Key Points

  • The error lies in the part 'was enagaged' in the given sentence.
  • Teacher and student are two subjects joined by and.
  • If the subject consists of two or more words that are connected by and then the subject is plural.
  • To maintain the subject-verb agreement, plural subjects need a plural verb.
  • Was engaged is incorrect as was is a singular verb.
  • Thus, option 3 is the correct answer.

So the correct sentence is- The teacher and her student were engaged in a discussion on the current political crisis

BDCA

Why this answer is correct

The correct answer is option 3) i.e., 'BDCA'.

Key Points 

  • When arranging sentences, it is easier to order the first few; and then eliminate the options accordingly.
  • The first sentence of a paragraph is usually independent and introduces a topic. The second one provides more information about it.
  • Here, only B is independent and introduces the topic which deals with the belief in God and how that believe is expressed through prayers and vows.
  • So, B becomes the first sentence of the passage.
  • Both options 1 and 3 show sentence B as the first sentence.
  • So, we need to find the second sentence which will be either sentence A or D.
  • Sentence A questions about the path that can be taken to reach our goals. But we need a mention of these goals first, before a question regarding them can be put forth.
  • So, sentence D which talks about how there are variations and different paths to reach or believe in God, occupies the second position.
  • So, D must come after B. Then BD is the correct order.
  • As per option 3, the full sequence is : BDCA.
  • B. Many of us believe in God, do our daily prayers and vow to be good.
  • D. There may be variations in our chosen ideals of Him, but each of us believes in Him nevertheless.
  • C. But unfortunately, when it comes to putting our ideas into practice, we procrastinate.
  • A. How will we ever reach our goal if we don't follow our ideals and principles and follow the path we say we believe in?
  • This sequence is logically correct, making option 3 the correct answer.

    CABD

  3. COption (c)

    BDAC

  4. DOption (d)

    ABDC

View answer & explanation

Correct answer

Answer: (a)A.

CBDA

Why this answer is correct

The correct answer is option 1) i.e., 'CBDA'.

Key Points

  • When arranging sentences, it is easier to order the first few; and then eliminate the options accordingly.
  • The first sentence of a paragraph is usually independent and introduces a topic. The second one provides more information about it.
  • Here, only C is independent and introduces the topic which deals with a declaration made by scientists regarding a disease.
  • So, C becomes the first sentence of the passage.
  • Both options 1 and 2 show sentence C as the first sentence.
  • So, we need to find the second sentence which will be either sentence A or B.
  • Sentence A talks about how few people know the long history of soap making. This sentence does not provide more information on sentence C. So, it cannot occupy the second position.
  • But sentence B talks about how (they) are recommending frequent hand washes as a prevention measure. This links sentence B to sentence C which had talked about a disease. Logically a disease needs to be prevented.
  • So, B must come after C. Then CB is the correct order.
  • As per option 1, the full sequence is : CBDA.
  • C. Scientists have declared that COVID-19 is here to stay.
  • B. As a prevention, they recommend the frequent washing of hands for 20 seconds.
  • D. This advice is practical and easy to follow as soap is a common and inexpensive consumer product.
  • A. Yet few people know the long history of making soap.
  • This sequence is logically correct, making option 1 the correct answer.

Question 18

  1. AOption (a)

    No improvement

  2. BOption (b)

    that buys more

  3. COption (c)

    that bought more

  4. DOption (d)

    that buying more

View answer & explanation

Correct answer

Answer: (d)D.

that buying more

Why this answer is correct

The correct answer is option 4) i.e., 'that buying more'.

Key Points

  • The underlined part of the given sentence is incorrect as buy is the simple present tense.
  • The given sentence implies that the action of buying things is a continuous procedure.
  • So, the simple present tense buy should be replaced with the present continuous tense form buying.
  • So, option 4 will improve the underlined segment in the given sentence.

So the correct sentence is- The advertising industry wants us to believe that buying more stuff will make us happier.

Question 19

Select the most appropriate option to substitute the underlined segment in the given sentence. If there is no need to substitute it, select 'No substitution'.

    were kept

  2. BOption (b)

    was kept

  3. COption (c)

    No substitution

  4. DOption (d)

    keeps

View answer & explanation

Correct answer

Answer: (a)A.

were kept

Why this answer is correct

The correct answer is option 1) i.e., 'were kept'.

Key Points

  • The underlined part of the given sentence is incorrect as was keeping is the past continuous tense form of the verb keep.
  • The given sentence is in simple past tense form and so the past continuous tense form cannot be used.
  • The simple past tense form of keep is kept.
  • We need to use the linking verb were as the sentence deals with the third person plural (they for the miscreants → (they) were kept).
  • So, option 1 is the most appropriate option to substitute the underlined segment in the given sentence.

So the correct sentence is- The miscreants were shifted to another building that same evening and were kept in custody by the police.

Question 20

Select the correct indirect form of the given sentence.

Correct answer

Answer: (d)D.

Sitab requests Madam to watch that program on their folk songs.

Why this answer is correct

The correct answer is option 4) i.e., 'Sitab requests Madam to watch that program on their folk songs.'

Key Points

  • The given sentence is a form of imperative sentence where a request has been made by using the word please.
  • We need to follow the steps to change an imperative sentence to indirect speech - 
  • The reporting verb says is changed into requests.
  • Put that between the reporting and reported speeches.
  • The first person our will be changed into their.
  • The tense of the given sentence is present tense (watch) which remains unchanged in the indirect sentence.
  • The verb to is added before the verb of the reported speech (watch).
  • Eventually, we will get the final sentence- Sitab requests Madam to watch that program on their folk songs.

View answer & explanation

Correct answer

Answer: (c)C.

5,280

Why this answer is correct

Given: 

Number of students (initially) = 90

Total number of students = 120

Expenditure of mess increased by 560

Average expenditure per head diminishes by 10

Calculation:

Let average expense per day be x

Total expense = 90x

After admission of 30 more students,

Total Expense = 90x + 560

Average Expense = x - 10

According to the question,

120(x - 10) = 90x + 560

⇒ 30x = 1760

⇒ x = 1760/30

⇒ 90x = 1760/30 × 90 = 1760 × 3 = 5280

Thus, Original Expenditure = Rs. 5280

∴ Required answer is Rs. 5280

  4. DOption (d)

    56

View answer & explanation

Correct answer

Answer: (d)D.

56

Why this answer is correct

Shortcut Trick

Total distance to cross = 565 + 975 = 1540 m

Speed of the train = 99 km/h = 99 × 5/18 = 55/2 m/s

Time taken = Total Distance ÷ Speed = 1540 ÷ (55/2) = 56 seconds

∴ The correct answer is 56 seconds.

Alternate Method

Given:

Length of the train = 565 m

Length of the tunnel = 975 m

Speed of the train = 99 km/h

Formula Used:

Time = Total Distance ÷ Speed

To convert speed from km/h to m/s, multiply by 5/18.

Tunnel (975 m)

Train (565 m) 99 km/h

Total Distance = 1540 m

Calculations:

⇒ Total Distance = Length of Train + Length of Tunnel

⇒ Total Distance = 565 + 975 = 1540 m

⇒ Speed of the train in m/s = 99 × 5/18

⇒ Speed = 11 × 5/2 = 55/2 m/s

⇒ Time taken = Total Distance ÷ Speed

⇒ Time = 1540 ÷ (55/2)

⇒ Time = (1540 × 2) ÷ 55

⇒ Time = 28 × 2 = 56 seconds

∴ The correct answer is 56 seconds.

Additional Information

Speed Conversion

To convert speed from km/h to m/s, multiply by 5/18. To convert from m/s to km/h, multiply by 18/5.

Crossing an Object with Length

When a train crosses a platform, bridge, or tunnel, the total distance covered is the sum of the length of the train and the length of the object being crossed.

Crossing a Point Object

When a train crosses a stationary man, pole, or tree, the total distance covered is equal to the length of the train alone.

Relative Speed

If two trains move in opposite directions, their relative speed is S1 + S2. If they move in the same direction, it is S1 − S2.

12%

Why this answer is correct

Calculation:

No. worker whose expenses is between 100 to 150 = 20

No. worker whose expenses is between 150 to 200 = 40

No. worker whose expenses is between 200 to 250 = 15

Total = 20 + 40 + 15 = 75

No. worker whose expenses is between 350 to 400 = 40

No. worker whose expenses is between 400 to 450 = 16

No. worker whose expenses is between 450 to 500 = 10

Total = 40 + 16 + 10 = 66

Difference = 75 - 66 = 9

% = 9/75 × 100 = 12%

∴ Required answer is 12%

Concept used:

Calculation:

\(4 \left{2\left(\frac{3}{4} \ \text{of} \ 24 - 1\right) + 3 (7\div x) - 5 × 8 + 1 \right} = 20^2 ?\)

⇒ 4{2(3/4 × 24 - 1) + 3 × 7/x - 5 × 8 + 1} = 202

⇒ 4{2(18 - 1) + 3 × 7/x - 5 × 8 + 1} = 202

⇒ 4{34 + 3 × 7/x - 5 × 8 + 1} = 202

⇒ 4{34 + 21/x - 40 + 1} = 400

⇒ {34 + 21/x - 40 + 1} = 100

⇒ 21/x = 100 + 40 - 34 - 1

⇒ 21/x = 105

2

Why this answer is correct

Given: 

985x3678y is divisible by 72,

Concept used:

A number will be divisible by 8 if the last 3 digit of a number is divisible by 8.

A number will be divisible by 9 if the sum of the digits is divisible by 9.

Calculation:

A number will be divisible by 8 if the last 3 digit of a number is divisible by 8.

⇒ 31y will be divisible by 8 if and only if y = 2

So, the number becomes 87605x312

Now, The sum of digits is (32 + x)

The number will be divisible by 9 if the sum of the digits is divisible by 9.

For this x must be 4     [x is a digit, x can't be 13]

Why this answer is correct

Given:

The base of a triangle is equal to the perimeter of a square whose diagonal is 7√2 cm7√ 2 \ cm

Height is equal to the side of a square whose area is 169 cm2

Concept used:

Area of a triangle = 1/2 × base × height

Side of a square = Diagonal/√2

SIde of a square = √(Side square)2

Calculation:

Side of the 1st square = 7

Perimeter = 7 × 4 = 28

So, the base of the triangle = 28 cm

Side of the 2nd square = 13

So, the height of the triangle is 13 cm

Area = 1/2 × 28 × 13

⇒ 182 cm2

∴ Area of the triangle is 182 cm2

View answer & explanation

Correct answer

Answer: (d)D.

7.5

Why this answer is correct

Shortcut Trick

A completes 1/2 work in 6 days (half of 12 days).

B finishes the remaining 1/2 work in 10 days, so B takes 20 days for full work.

Together Time = (A × B) ÷ (A + B) = (12 × 20) ÷ (12 + 20)

Together Time = 240 ÷ 32 = 7.5 days.

∴ The correct answer is 7.5 days.

Alternate Method

Given:

Time taken by A = 12 days

Work done by A in 6 days = 6 ÷ 12 = 1/2

Remaining work = 1 − 1/2 = 1/2

Time taken by B to finish 1/2 work = 10 days

⇒ Time taken by B to finish full work = 10 × 2 = 20 days

PersonDaysTotal WorkEfficiency
A1260 (LCM)5
B203

Calculations:

⇒ Total Efficiency of (A + B) = 5 + 3 = 8 units/day

⇒ Total Work = 60 units

⇒ Time taken by (A + B) together = Total Work ÷ Total Efficiency

⇒ Time = 60 ÷ 8

⇒ Time = 7.5 days

∴ The correct answer is 7.5 days.

Additional Information

Efficiency and Time Relationship

Efficiency is inversely proportional to time taken. If a person takes n days to complete a work, their 1-day efficiency is 1/n.

Combined Work Formula

For two people with individual completion times x and y, the time taken together is (x × y) ÷ (x + y).

Work done by different efficiencies

Total Work = Σ(Efficiency × Time). This concept is useful when people leave or join work midway.

When a ladder makes an angle θ with a vertical wall, the height reached (h) is the adjacent side of the triangle.

Formula: Height = Ladder Length × cos(θ)

Height = 10 × cos(30°) = 10 × (√3 ÷ 2)

Height = 5 × 1.73 = 8.65 m

∴ The correct answer is 8.65 m.

Alternate Method

Given: Ladder length = 10 m, Angle with wall = 30°, √3 = 1.73.

In the right-angled triangle ABC, let AC be the wall, BC be the ground, and AB be the ladder.

⇒ Hypotenuse (AB) = 10 m

⇒ Angle with wall (∠BAC) = 30°

⇒ cos(∠BAC) = Adjacent side (AC) ÷ Hypotenuse (AB)

⇒ cos(30°) = Height (h) ÷ 10

⇒ (√3 ÷ 2) = h ÷ 10

⇒ h = (10 × √3) ÷ 2

⇒ h = 5 × 1.73

⇒ h = 8.65 m

∴ The correct answer is 8.65 m.

Additional Information

Trigonometric Ratios

For a right-angled triangle, sin θ = opposite/hypotenuse and cos θ = adjacent/hypotenuse.

Angle with Ground vs Wall

If the angle with the wall is θ, the angle with the ground is (90° − θ). For θ = 30°, the angle with the ground is 60°.

Pythagoras Theorem

In any right triangle, (Base)2 + (Height)2 = (Hypotenuse)2.

Common Trig Values

cos(30°) = √3/2 ≈ 0.866; sin(30°) = 1/2 = 0.5; tan(30°) = 1/√3 ≈ 0.577.

View answer & explanation

Correct answer

Answer: (a)A.

1009\frac{100}{9}

Why this answer is correct

Given:

Two numbers are less than third number by 37% and 30% respectively.

Calculations:

Let the third number(C) be '100'.

⇒ The first number(A) = (100 - 37)% of 100

⇒ A = 63

The second number(B) = (100 - 30)% of 100

⇒ B = 70 

Now, Percent by which B is more than by A is = {(70 - 63)/63} × 100

⇒ 1009\frac{100}{9} 

∴ The percentage by which the second number is more than the first is 1009\frac{100}{9}%
