13. Directions: Select the phrase from the options below that should replace the underlined phrase in the sentence to make it grammatically correct. If the sentence is already correct, select ‘No correction required’ as your answer.The film was so more exciting than I thought it would be.

A. Far more exciting

B. Much more exciting

C. So much more exciting

D. Very more exciting

E. No correction required

Solution

The correct answer is ‘Option 2’.

Key Points

The error in the sentence is the use of “so” before “more.” The correct comparative formation is “much more.”
The word “much” is used to modify comparatives, i.e., to show that one thing has a greater degree or extent of a quality than another.
So, the correct construction would be, “The film was much more exciting than I thought it would be.“
Thus, ‘Much more exciting‘ rectifies the error and maintains the intended sense of the sentence.

Therefore, the correct answer is ‘Much more exciting’.

Additional Information

‘Far more exciting‘: Though not incorrect, this phrase intensifies the comparison more than might be intended in the original sentence.
‘So much more exciting‘: This phrase is heavy-handed and is not the exact equivalent of the original sentence’s meaning.
‘Very more exciting‘: This phrase is incorrect because “very” cannot be used in this context.
‘No correction required‘: This is not suitable because the original sentence is grammatically incorrect.

14. Directions: Select the phrase from the options below that should replace the underlined phrase in the sentence to make it grammatically correct. If the sentence is already correct, select ‘No correction required’ as your answer.John mentioned that he loves to playing tennis at the club.

A. Loves playing

B. Loves to play

C. Loved to play

D. Loved playing

E. No correction required

Solution

The correct answer is ‘Option 2’.

Key Points

The error in the sentence lies in the use of the gerund form “playing” after “to.”
The infinitive ‘to‘ should be followed by the base form of the verb, in this case, ‘play‘.
So, the phrase would be “John mentioned that he loves to play tennis at the club.“
Here, ‘Loves to play‘ rectifies the error in question and maintains the intended meaning of the sentence.

Therefore, the correct answer is ‘Loves to play’.

Additional Information

‘Loves playing‘: This is grammatically correct but changes the original sentence’s language slightly. In some dialects, this may even imply a slight difference in how often he plays.
‘Loved to play‘: This changes the sentence’s tense. The original sentence is in the present tense, while this is in the past.
‘Loved playing‘: This too changes the sentence’s tense from present to past.
‘No correction required‘: This is not applicable as the original sentence contains a mistake.

15. Directions: Select the phrase from the options below that should replace the underlined phrase in the sentence to make it grammatically correct. If the sentence is already correct, select ‘No correction required’ as your answer.Elizabeth loves dogs; she loves cats also.

A. But she loves cats too

B. She too loves cats

C. She also loves cats

D. Also, she loves cats

E. No correction required

Solution

The correct answer is ‘Option 3’.

Key Points

In the given sentence, the usage of ‘also‘ at the end of the phrase is not incorrect, but it is more common and grammatically preferred to position ‘also‘ in front of the verb it modifies.
The correct phrase “She also loves cats” has a minor reordering that makes the sentence sound more natural.
So, the proper way to express this would be, “Elizabeth loves dogs; she also loves cats.“

Therefore, the correct answer is ‘She also loves cats’.

Additional Information

‘But she loves cats too‘: This phrase adds a contrast not present in the original sentence and is therefore not a suitable replacement.
‘She too loves cats‘: While grammatically correct, this alternative is somewhat less common and less informal than ‘She also loves cats’.
‘Also, she loves cats‘: This option, although technically acceptable, moves the word ‘also’ to a position that changes the sentence’s rhythm and natural feel significantly.
‘No correction required‘: This is not applicable since the placement of “also” is unconventional, even if it’s not technically incorrect.

Question:

Which of the following is the most appropriate option to fill in the blank labelled as (1)?

A. extracted

B. gleaned

C. derived

D. presupposed

E. ignored

Solution

The correct answer is: Option 3.

Key Points

“Derived” refers to obtaining something from a specified source; it means to take, receive, or obtain, especially from a specified source. (व्युत्पन्न)
- Example: The word ‘cryptography‘ is derived from the Greek words ‘kryptos‘, meaning hidden, and ‘graphein‘, meaning to write.
This is because the sentence discusses how meaning comes “not from things as they are, but rather the idea of them”.
Hence, we can infer that the most appropriate option to fill in the blank labelled as (1) is ‘derived’.

Therefore, the correct answer is: Derived.

Key Points

In the given sentence, no improvement is required in any of the parts or there is no error in the sentence.
The given statement in the sentence is a negative statement.
The use of the negative word ‘seldom‘ which means not often; rarely, indicates the statement is a negative statement.
A few negative words are: Scarcely, hardly, rarely, barely, seldom, no, nothing, neither, few, none, etc.
- Example: You seldom go to the beach, do you?
When the statement is negative, we use a positive question tag.
- She is not a girl, is she?
And, if the statement is positive, we use a negative question tag.
- She is a girl, isn’t she?

Hence, the correct answer is option 5.

Correct Sentence: She seldom smokes, does she?

22. Directions: Read the sentence given below to find out if it contains an error. The error, if any, will be in one part of the sentence. If the sentence is error-free, select No error or option 5. Ignore errors of punctuation if any.

Key Points

In the given sentence, the use of the positive question tag ”has she” is incorrect.
The given statement in the sentence is a positive statement.
When the statement is positive, we use a negative question tag.
- He is a boy, isn’t he?
And, if the statement is negative, we use a positive question tag.
- He is not a boy, is he?
Therefore, the negative question tag ”hasn’t she” should be used in place of the positive question tag ”has she”.

Hence, the correct answer is option 4.

D. D

E. E

Solution

The correct answer is ‘C‘ i.e. this part of the sentence has an error.

Key Points

In the third part of the given sentence, the use of the phrase verb ”give away” is incorrect.
The phrasal verb ”give away” means to give something free as a gift or donation.
- Example: We have five pairs of free tickets to give away.
The phrasal verb ”give up” should be used in place of the phrasal verb ”give away”.
The given sentence is talking about discontinuing or quitting smoking.
The phrasal verb ”give up” means to stopdoing or consuming something.
- Example: Her illness compelled her to give up her job.

Hence, the correct answer is option 3.

E. E

Solution

The correct answer is ‘D‘ i.e. this part of the sentence has an error.

Key Points

In the fourth part of the given sentence, the use of the plural form of the noun ‘advices’ is incorrect.
The noun ‘advice‘ is an uncountable noun i.e. we cannot count it.
Uncountable nouns usually do not have a plural form and are used with a singular verb.
Advice is uncountable, we say a piece of advice (not ‘an advice’) and some advice (not ‘some advices’).
For Example:
- My advices are quite disinterested.
- My advice is quite disinterested.
Therefore, the noun ‘advice’ should be used in place of the noun ‘advices’.

Hence, the correct answer is option 4.

Correct sentence: My sister gave me a lot of advice.

Additional Information

The nouns given below seem plural in form but in actuality are singular:
- News, billiards, summons, physics, measles, innings, etc.
For Example:
- Physics is an interesting subject.

A. A

B. B

C. C

D. D

E. E

Solution

The correct answer is ‘D‘ i.e. this part of the sentence has an error.

Key Points

In the fourth part of the given sentence, the use of the base form of the verb ‘help’ is incorrect.
The given sentence is the third conditional sentence explaining that present circumstances would be different if something different had happened in the past.
The third conditional sentence format: past perfect, modal auxiliary (would, could, should, etc.) + have + past participle.
When using the third conditional, we use the past perfect (i.e., had + past participle) in the if-clause and the modal auxiliary (would, could, should, etc.) + have + past participle in the main clause.
Therefore, the past participle form of the verb ‘helped‘ should be used in place of the base form of the verb ‘help‘.

Hence, the correct answer is option 4.

Correct sentence: If she had contacted me, I would have helped her.

43. The investment made by A and B are in the ratio 6 : 5. If 33.33% of total profit goes to charity and A gets Rs. 72,720 Rs as his share of profit then what is the amount of total profit.

A. Rs. 2,00,000

B. Rs. 1,99,980

C. Rs. 2,000

D. Rs. 20

E. None of these

Solution

Given that:

Investment of A and B = 6 : 5

A gets the profit = Rs. 72,720

Formula used

Profit = time × money

Investment ratio is equal to profit ratio

Calculation:

Let the total profit be 100 units

Remaining profit after donated = 100 – (33.33% of 100) =2/3 of total profit

Share of A’s profit = Rs. 72,720

⇒ 6x = 72720

⇒ x = 12120

⇒ 11x = 11 × 12120 = 133320

So, profit after donated = Rs. 133320

Total profit = 3/2 × 133320 = 199980

∴ The total profit is Rs. 1,99,980

44. In the given question, two equations numbered l and II are given. Solve both the equations and mark the appropriate answer.

I. x² + 11x – 60 = 0II. y² – 17y + 60 = 0

A. x > y

B. x < y

C. x ≥ y

D. x ≤ y

E. x = y or no relationship could be established

Solution

I. x²+ 11x – 60 = 0

⇒ x² + 15x – 4x – 60 = 0

⇒ x(x + 15) – 4(x + 15) = 0

⇒ (x + 15)(x – 4) = 0

⇒ x = -15, 4

II. y²– 17y + 60 = 0

⇒ y² – 12y – 5y + 60 = 0

⇒ y(y – 12) – 5(y – 12) = 0

⇒ (y – 12)(y – 5) = 0

⇒ y = 12, 5

When x = -15, y = 12, then x < y

When x = -15, y = 5, then x < y

When x = 4, y = 12, then x < y

When x = 4, y = 5, then x < y∴ x and y are related as x < y

45. In the given question, two equations numbered l and II are given. Solve both the equations and mark the appropriate answer.

I. x² – 5x + 6 = 0II. y² + 5y – 6 = 0

A. x > y

B. x < y

C. x ≥ y

D. x ≤ y

E. x = y or no relationship could be established

Solution

I. x²– 5x + 6 = 0

⇒ x² – 3x – 2x + 6 = 0

⇒ x(x – 3) – 2(x – 3) = 0

⇒ (x – 3)(x – 2) = 0

⇒ x = 3, 2

II. y²+ 5y – 6 = 0

⇒ y² + 6y – y – 6 = 0

⇒ y(y + 6) – 1(y + 6) = 0

⇒ (y + 6)(y – 1) = 0

⇒ y = – 6, 1

When x = 3, y = – 6, then x > y

When x = 3, y = 1, then x > y

When x = 2, y = – 6, then x > y

When x = 2, y = 1, then x > y∴ x and y are related as x > y

A. x > y

B. x < y

C. x ≥ y

D. x ≤ y

E. x = y or no relationship could be established

Solution

I. 8x²– 9x + 1 = 0

⇒ 8x² – 8x – x + 1 = 0

⇒ 8x(x – 1) – 1(x – 1) = 0

⇒ (x – 1)(8x – 1) = 0

⇒ x = 1, 1/8

II. 4y²– 9y + 2 = 0

⇒ 4y² – 8y – y + 2 = 0

⇒ 4y(y – 2) – 1(y – 2) = 0

⇒ (y – 2)(4y – 1) = 0

⇒ y = 2, 1/4

When x = 1, y = 2, then x < y

When x = 1, y = 1/4, then x > y

When x = 1/8, y = 2, then x < y

When x = 1/8, y = 1/4, then x < y∴ No relationship could be established between x and y

A. Quantity A ≥ Quantity B

B. Quantity A ≤ Quantity B

C. Quantity A < Quantity B

D. Quantity A > Quantity B

E. Quantity A = Quantity B or No relation

Solution

Quantity A:

Let the speed of boat be x km/hr

Speed of stream be y km/hr

According to the question,

45/(x + y) = 5

⇒ x + y = 9 —-(i)

35/(x – y) = 5

⇒ x – y = 7 —-(ii)

Solving equation (i) and (ii) we get,

x = 8 km/hr

y = 1 km/hr

∴ Speed of stream is 1 km/hr

Quantity B: 2 km/hr∴ Quantity A < Quantity B

A. 16 liters

B. 5 liters

C. 12 liters

D. 20 liters

E. None of the above

Solution

Given:

Old ratio of apple juice to orange juice = 2 : 3

New ratio = 1 : 2

Orange juice added = 2 liters

Calculations:

Here, assume X to be initial quantity of mixture

⇒ Quantity of apple juice in old mixture = (2 / 5) × X

⇒ Quantity of orange juice in old mixture = (3 / 5) × X

Now, 2 liters is added

⇒ ((2/5) × X)/(((3/5) × X) + 2) = 1 : 2

⇒ 2X/(3X + 10) = 1 : 2

⇒ 4X = 3X + 10

⇒ X = 10 liters

⇒ New mixture = 10 + 2∴ Quantity of new mixture is 12 liters

64. A shopkeeper bought an article at certain cost. He sold it at profit of 8%. If he sold at Rs.80 more then he would earn 12% of profit. Find the profit he earned.

A. Rs.220

B. Rs.180

C. Rs.210

D. Rs.130

E. Rs.160

Solution

Given:

Let cost price of an article be Rs.a.

⇒ selling price of an article = a × 108/100 = Rs.27a/25

⇒ new selling price of an article = a × 112/100 = 27a/25 + 80

⇒ 28a/25 = 27a/25 + 80

⇒ a = 2000

Cost price of an article = Rs.2000

Selling price of an article = 2000 × 27/25 = Rs.2160

∴ Profit he earned = 2160 – 2000 = Rs.160

65. The height of the cylinder is half of the radius of the cylinder, its volume is 539 cm³, then what is the total surface area of the cylinder?

A. 452 cm²

B. 462 cm²

C. 362 cm²

D. 400 cm²

E. 346 cm²

Solution

Given:

The height of the cylinder = half of the radius of the cylinder

The volume of the cylinder = 539 cm³

Formula Used:

The volume of the cylinder = πr²h

The total surface area of the cylinder = 2πr(r + h)

Where, r = Radius of the cylinder

h = Height of the cylinder,

π = 22/7

Calculation:

Let the radius of the cylinder(r) be x cm.

Then, the height of the cylinder(h) = (x/2) cm

According to the question,

πr2h = 539

⇒ (22/7) × x² × (x/2) = 539

⇒ (11x³)/7 = 539

⇒ x³ = 539 × (7/11)

⇒ x³ = 49 × 7

⇒ x³ = 343

⇒ x = 7

Hence, r = 7 cm

h = (7/2) cm

The total surface area of the cylinder = 2πr(r + h)

⇒ 2 × (22/7) × 7 × {7 + (7/2)}

⇒ 44 × (21/2)

⇒ 22 × 21

⇒ 462 cm²

∴ The total surface area of the cylinder will be 462 cm².
