View answer & explanation

Correct answer

Answer: (d)D.

18

Why this answer is correct

Let the present age of Manish and Parvez be 'M' and 'P' respectively.

As per Question: Six year ago, Parvez’s age was same as the present age of Manish

Therefore, P - 6 = M → P - M = 6 ----(1)

Again, the present age of Parvez is one-fourth more than that of Manish's present age

Therefore, P = (1/4 × M) + M → P = 5M/4 ---- (2)

From (1) and (2)

P = 30 and M = 24

Therefore Present age of Parvez and Manish is 30 and 24 respectively.

Now, if we double the present age of Manish = 24 × 2 = 48

So Parvez will be of 48 years after = 48 - 30 = 18 Years

Hence, the correct answer is 18 Years.

View answer & explanation

Correct answer

Answer: (d)D.

32 or 18

Why this answer is correct

The pattern followed here is,

14 (16) 18

→ (18 - 14)2 = (4)2 = 16

33 (64) 25

→ (33 - 25)2 = (8)2 = 64

Similarly,

25 (49) A

→ (25 - A)2 = (7)2 or (A - 25)2 = (7)2

→ 25 - 7 or 25 + 7

→ 18 or 32

Hence, the answer will be either ‘18 or 32’.

Why this answer is correct

Litmus is a water-soluble mixture of different dyes extracted from lichens. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity.

Concept:

Metals react with oxygen to form metallic oxides.

These metallic oxides are basic in nature

Metal + Oxygen → Metallic oxide

Example:

When magnesium burns in air it combines with the oxygen of the air to form magnesium oxide

2 Mg + O2 → 2 MgO

Magnesium oxide dissolves in water to form magnesium hydroxide solution

MgO + H2O → Mg(OH)2

Magnesium hydroxide turns red litmus blue which shows its basic nature.

    1/3

View answer & explanation

Correct answer

Answer: (c)C.

1

Why this answer is correct

Shortcut Trick

Use the property: If θ1 + θ2 = 90°, then tan θ1 × tan θ2 = 1.

Pairing terms: (tan 6° × tan 84°) × (tan 36° × tan 54°) × tan 45°.

As 6 + 84 = 90 and 36 + 54 = 90, both pairs become 1.

Final calculation: 1 × 1 × 1 = 1.

∴ The correct answer is 1.

Alternate Method

Given: tan 6°, tan 36°, tan 84°, tan 54°, tan 45°

Formula: tan (90° − θ) = cot θ and tan θ × cot θ = 1

⇒ Expression = tan 6° × tan 36° × tan (90° − 6°) × tan (90° − 36°) × tan 45°

⇒ Expression = tan 6° × tan 36° × cot 6° × cot 36° × tan 45°

⇒ Expression = (tan 6° × cot 6°) × (tan 36° × cot 36°) × 1

⇒ Expression = 1 × 1 × 1 = 1

∴ The correct answer is 1.

Additional Information

Complementary Angle Identities

For any angle θ, sin (90° − θ) = cos θ, tan (90° − θ) = cot θ, and sec (90° − θ) = cosec θ.

Standard Values

Value of tan 45° = 1 and cot 45° = 1 are frequently used to simplify trigonometric products.

Product Rule

If A + B = 90°, then tan A × tan B = 1 and cot A × cot B = 1.

  3. COption (c)

    350

  4. DOption (d)

    450

View answer & explanation

Correct answer

Answer: (a)A.

250

Why this answer is correct

Let the wages of A and B be Rs. x and Rs. y respectively.

Since A is paid 160% of what B is paid,

⇒ (x/y) × 100 = 160

⇒ x = 160y/100 = 8y/5       ---(1)

Total wage = Rs. x + Rs. y = Rs. (8y/5) + y {Using (1)} = Rs. 13y/5 = Rs. 650 (given)

⇒ y = 650 × 5/13 = 250

∴ B is paid Rs. 250.

Two laborers A and B are paid a total of Rs. 650 per day. If A is paid 160 percent of what is paid to B, how much (in Rs) is B paid?

  4. DOption (d)

    (0, -13)

View answer & explanation

Correct answer

Answer: (d)D.

(0, -13)

Why this answer is correct

Let the co-ordinates of the vertex C be (x, y).

Then,

Centroid = ((3 + 0 + x)/3, (-4 + 5 + y)/3) = (1, -4)

⇒ (3 + x)/3 = 1                       and ⇒ (1 + y)/3 = -4

⇒ 3 + x = 3                          ⇒ 1 + y = -12

⇒ x = 0                                ⇒ y = -13

∴ Co-ordinates of the vertex C are (0, -13).

    -4/15

  4. DOption (d)

    15/4

View answer & explanation

Correct answer

Answer: (d)D.

15/4

Why this answer is correct

[2(4x/5 - 3/4)]/3 - 5/3 = -1/6

⇒ [2(4x/5 - 3/4)]/3 = 5/3 – 1/6 = 9/6 = 3/2

⇒ [2(4x/5 - 3/4)] = 3/2 × 3 = 9/2

⇒ (4x/5 - 3/4) = 9/2 × 1/2 = 9/4

⇒ 4x/5 = 9/4 + 3/4 = 12/4 = 3

⇒ x = 3 × 5/4 = 15/4

∴ x = 15/4

Answer: (a)A.

20

Why this answer is correct

Let x be added to each number i.e. 55, 100, 65 and 116, such that the resulting numbers are in continued proportion.

⇒ (55 + x) : (100 + x) = (65 + x) : (116 + x)

⇒ (55 + x) (116 + x) = (65 + x) (100 + x)

⇒ x2 + 171x + 6380 = x2 + 165x + 6500

⇒ 6x = 120

⇒ x = 20

∴ 20 must be added to each number.

So, m = -a/5

⇒ Slope = -a/5 = -4/3 (given)

⇒ a/5 = 4/3

∴ a = 20/3

  3. COption (c)

    (7, -3)

  4. DOption (d)

    (7, 3)

View answer & explanation

Correct answer

Answer: (b)B.

(-7, 3)

Why this answer is correct

Let the reflected point be (x, y).

Then the midpoint of (-1, 3) and (x, y) i.e. [(x-1)/2, (y+3)/2] must lie on the line x = -4.

⇒ (x – 1) / 2 = -4

⇒ x = -8 + 1 = -7

Since the line joining the original and the reflected point in perpendicular to x = -4, hence its slope will be equal to 0.

⇒ [y – 3]/[(-7) – (-1)] = 0

⇒ y – 3 = 0

⇒ y = 3

∴ The reflected point is (-7, 3).

90

Why this answer is correct

Join OP and OQ

Since OQ = OP = OR (radius)

⇒ QS = OR = OQ

⇒ ∠QOS = ∠QSO = 30°

In triangle SQO,

⇒ ∠QOS + ∠QSO + ∠SQO = 180°

⇒ ∠SQO = 120°

In triangle POQ,

OP = OQ (both are radius)

⇒ ∠OQP = ∠QPO = 180° - 120° = 60°

∠QPO + ∠POQ = ∠OQS (Exterior angle property)

⇒ ∠QPO + ∠POQ = 120°

⇒ ∠POQ = 120° - ∠QPO = 120° - 60° = 60°

⇒ ∠POS = 60° + 30° = 90°

∴ ∠POR = 180° - ∠POS = 90°

Cost price = Rs. 1600

List price = Rs. 1600 + Rs. 1600 × 60/100 = Rs. 1600 + Rs. 960 = Rs. 2560

Discount = Rs. 2560 × 25/100 = Rs. 640

∴ Selling price = Rs. 2560 – Rs. 640 = Rs. 1920

Question 68

Sum of a fraction and thrice of its reciprocal is 73/20. What is the fraction?

  1. AOption (a)

    4/5

  2. BOption (b)

    9/4

  3. COption (c)

    4/9

  4. DOption (d)

    5/4

View answer & explanation

Correct answer

Answer: (d)D.

5/4

Why this answer is correct

Shortcut Trick

Test the options to satisfy the condition: Fraction + 3 × (Reciprocal) = 73/20.

Checking option 5/4:

Reciprocal = 4/5

Thrice reciprocal = 3 × (4/5) = 12/5

Sum = 5/4 + 12/5 = (25 + 48) / 20 = 73/20. This matches the given condition.

∴ The correct answer is 5/4.

Alternate Method

Given:

Let the fraction be x.

Sum of x and 3 × (1/x) = 73/20

Formula Used:

Quadratic equation: ax2 + bx + c = 0

Calculations:

⇒ x + 3/x = 73/20

⇒ (x2 + 3) / x = 73/20

⇒ 20(x2 + 3) = 73x

⇒ 20x2 − 73x + 60 = 0

⇒ 20x2 − 48x − 25x + 60 = 0

⇒ 4x(5x − 12) − 5(5x − 12) = 0

⇒ (4x − 5)(5x − 12) = 0

⇒ 4x − 5 = 0 or 5x − 12 = 0

⇒ x = 5/4 or x = 12/5

Comparing with options, the fraction is 5/4.

∴ The correct answer is 5/4.

Additional Information

Reciprocal Property

For any non-zero fraction a/b, its reciprocal is b/a. The product of a fraction and its reciprocal is always 1.

Quadratic Roots

A quadratic equation ax2 + bx + c = 0 can be solved using the discriminant D = b2 − 4ac. If D is a perfect square, roots are rational.

Proper vs Improper Fractions

A proper fraction has a numerator smaller than the denominator (e.g., 4/5), while an improper fraction has a numerator equal to or larger than the denominator (e.g., 5/4).

Question 69

If (x – 2)2 + (y + 3)2 + (z – 15)2 = 0, then what is the value of x + y + z – 5

  1. AOption (a)

    5

  2. BOption (b)

    9

  3. COption (c)

    15

  4. DOption (d)

    20

View answer & explanation

Correct answer

Answer: (b)B.

9

Why this answer is correct

(x – 2)2 + (y + 3)2 + (z – 15)2 = 0

Since all the three terms are positive

Their sum can be 0 only when all the 3 terms are 0

⇒ x – 2 = 0;  y + 3 = 0;       z – 15 = 0

⇒ x = 2;        y = -3;           z = 15

∴ x + y + z – 5 = 2 – 3 + 15 – 5 = 9

Question 70

If a3 + b3 = 35 and ab = 6, then what is the value of a + b?

  1. AOption (a)

    5

  2. BOption (b)

    8

  3. COption (c)

    2

  4. DOption (d)

    -8

View answer & explanation

Correct answer

Answer: (a)A.

5

Why this answer is correct

Given, a3 + b3 = 35

Using expansion,

(a + b) (a2 - ab + b2) = 35

⇒ (a + b) (a2 + b2 + 2ab -2ab – ab) = 35

⇒ (a + b) {(a + b)2 – 3ab} = 35

Since, ab = 6 (given)

⇒ (a + b) {(a + b)2 – 18} = 35

⇒ (a + b)3 – 18(a + b) – 35 = 0

Put a + b = x

⇒ x3 – 18x – 35 = 0

Using trial error method,

(Trick: Put values of x as given in the options)

Putting x = 5

L.H.S. = 125 – 90 – 35 = 0 = R.H.S.

 ∴ a + b = 5

Question 71

The two equal sides of an isosceles triangle is 20 cm each and the third side is 30 cm. What is the area (in cm2) of the triangle?

  1. AOption (a)

  2. BOption (b)

    100

  3. COption (c)

    75√7

  4. DOption (d)

    175

View answer & explanation

Correct answer

Answer: (c)C.

75√7

Why this answer is correct

Semi perimeter = (20 + 20 + 30)/2 cm = 35 cm

Using Heron’s formula,

∴ Area = √[35(35 – 20)(35 – 20)(35 – 30)] = 75√7

Question 72

A man travelled a distance of 60 km in 7 hours. He travelled partly on foot @ 6 km/hr and partly on bicycle @ 12 km/hr. What is the distance (in kms) travelled on foot?

  1. AOption (a)

    15

  2. BOption (b)

    9

  3. COption (c)

    48

  4. DOption (d)

    24

View answer & explanation

Correct answer

Answer: (d)D.

24

Why this answer is correct

Let the man travel x km on foot and y km on a bicycle.

Total distance travelled = x + y km = 60 km (given)

⇒ x + y = 60      ----(1)

Duration for which man travelled on foot = x km ÷ 6 km/hr = x/6 hrs

Duration for which man travelled on bicycle = y km ÷ 12 km/hr = y/12 hrs

Total travelling time = x/6 + y/12 hrs = 7 hrs (given)

⇒ (2x + y)/12 = 7

⇒ 2x + y = 84        ----(2)

Subtracting (1) from (2), we get

⇒ x = 24

∴ The man travelled 24 km on foot.

Question 73

The compound interest earned in two years at 12% per annum is Rs 10176. What is the sum (in Rs) invested?

  1. AOption (a)

    50000

  2. BOption (b)

    60000

  3. COption (c)

    40000

  4. DOption (d)

    80000

View answer & explanation

Correct answer

Answer: (c)C.

40000

Why this answer is correct

Let invested sum be Rs. P.

Interest rate, r = 12/100 = 0.12

Value of investment after 2 years = Rs. P + 10176

Using compound interest formula,

A = P (1 + r/n)nt

⇒ P + 10176 = P (1 + 0.12)2

⇒ P + 10176 = 1.2544P

⇒ 0.2555P = 10176

⇒ P = 40000

∴ Sum invested = Rs. 40000

Question 74

What is the sum of the first 11 terms of an arithmetic progression if the 4th term is 11 and the 7th term is -4?

  1. AOption (a)

    -75

  2. BOption (b)

    55

  3. COption (c)

    11

  4. DOption (d)

    100

View answer & explanation

Correct answer

Answer: (c)C.

11

Why this answer is correct

Let the first term be a and the common difference be r.

a4 = a + (4 – 1) r

⇒ a + 3r = 11 ------ (1)

a7 = a + (7 – 1) r 

⇒ a + 6r = -4 ------ (2)

Subtracting (1) from (2), we get

3r = -15

r = -5

a = 11 – 3 × (-5) = 26

Sum of first 11 terms = 11/2 [2 × 26 + (11 – 1) × (-5)] = 11

∴ The sum of the first 11 term is 11

Question 75

D and E are points on side AB and AC of ΔABC. DE is parallel to BC. If AD : DB = 2 : 5 and area of ΔABC is 98 cm sq, what is the area (in sq cm) of quadrilateral BDEC?

  1. AOption (a)

    90

  2. BOption (b)

    98

  3. COption (c)

    94

  4. DOption (d)

    86

View answer & explanation

Correct answer

Answer: (a)A.

90

Why this answer is correct

Shortcut TrickAD : DB = 2 : 5

So, AB = 7a

Area of ΔABC = 72a

⇒ 72a = 98 

⇒ a = 2

Area of quad BDEC = 72a - 22a

= 45a

= 90

<br>

Solution:

Since DE is parallel to BC.

⇒ ∠ABP = ∠ADQ ---- (1)

AD : DB = 2 : 5

⇒ DB/AD = 5/2

⇒ 1 + DB/AD = 1 + 5/2

⇒ (AD + DB)/AD = 7/2

⇒ AB/AD = 7/2 ---- (2)

In ΔABC and ΔADE

∠BAC = ∠DAE (common angle)

∠ABC = ∠ADE (corresponding angles) {using (1)}

∠ACB = ∠AED (corresponding angles)

⇒ ΔABC ~ ΔADE (by AAA)

⇒ AB/AD = BC/DE = 7/2 {using (2)}

⇒ DE = 2BC/7 ---- (3)

In ΔABP and ΔADQ

∠BAP = ∠DAQ (common angle)

∠ABC = ∠ADE (corresponding angles) {using (1)}

∠APB = ∠AQD = 90ᵒ

⇒ ΔABP ~ ΔADQ (by AAA)

⇒ AB/AD = AQ/AP = 7/2 {using (2)}

⇒ AQ = 2AP/7 ---- (4)

Area of ΔABC = 98 cm2

Area of ΔADE = 1/2 × DE × AQ = 1/2 × 2BC/7 × 2AP/7 = 4/49 × 1/2 × BC × AP = 4/49 × Area of ΔABC = 4/49 × 98 cm2 = 8 cm2

∴ Area of BDEC = 98 – 8 cm2 = 90 cm2

Why this answer is correct

The correct answer is: Eclipse.

Key Points

  • The word "transcend" means to go beyond the limits of something; to surpass or exceed. (अतिक्रमण करना)
  • Example: His performance transcends all expectations, setting a new benchmark.
  • "Eclipse" refers to overshadowing something or someone, making them seem less important by comparison. (ग्रहण)
  • Example: Her talent eclipses that of all her peers, making her the star of the show.
  • Hence, we can infer that the word similar in meaning to 'transcend' is 'eclipse'.

Therefore, the correct answer is: Option 1.

Additional Information

Here are the other options explained along with their Hindi meanings and example sentences:

  • Fizzle (फुसफुसाना): To fail or end weakly, especially after a promising start.
  • Example: The project started with great enthusiasm but eventually fizzled out.

4

Why this answer is correct

The correct answer is 4

Key Points

  • We use 'the' before the superlative degree of adjectives.

Example: the largest, the smallest

  • The superlative degree (or superlative) compares more than two things to show which has the least or greatest degree of the quality (e.g., brightest, most brightly).
  • Thus, the given sentence is correct.

Question 78

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

Repetition bred a sense of _____________ with the characters.

  1. AOption (a)

    familiarity

  2. BOption (b)

    familiar

  3. COption (c)

    familiarly

  4. DOption (d)

    familiarise

View answer & explanation

Correct answer

Answer: (a)A.

familiarity

Why this answer is correct

The blank would make complete sense if it is filled with a noun which could completely define the context. In the given options,’familiar’ is an adjective which would make no sense when used as a filler. “Familiarise” is a verb which is also an incorrect filler. Since there is no comparison going on in the statement, therefore, option 3 also cannot be used. Option 1 correctly fits the sentence and makes it meaningful.

Question 79

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".

  2. BOption (b)

    saw

  3. COption (c)

    seeing

  4. DOption (d)

    No improvement

View answer & explanation

Correct answer

Answer: (a)A.

Why this answer is correct

Here the correct answer is See.

Key Points:-

  • The statement clearly is said in the present tense.
  • Therefore, option 2 is already eliminated because it shows past tense.
  • Since the statement is also not said in the present continuous tense, therefore, we cannot use the 3rd option too.
  • The statement is said in the present tense and hence, option 1 is correct.

Therefore, the correct sentence is Take out your binoculars and see the Andromeda galaxy.

View answer & explanation

Correct answer

Answer: (a)A.

The house was remodelled by the homeowners to help it sell.

Why this answer is correct

The active voice is said in the past tense. The 2nd option is incorrect because it is given in the present tense which can be inferred by the use of "is". 

Options 3 and 4 are incorrect because it is given as a reason while the active voice of the statement is not told in a reason. Option 1 is correct passive voice of the given sentence.

Sentience

  1. AOption (a)

    Disregard

  2. BOption (b)

    Appreciation

  3. COption (c)

    Consciousness

  4. DOption (d)

    Perception

View answer & explanation

Correct answer

Answer: (a)A.

Disregard

Why this answer is correct

The correct answer is: Disregard.

Key Points

  • The word "Sentience" means the capacity to feel, perceive, or experience subjectively. (संवेदनशीलता)
  • Example: The sentience of animals is often a consideration in ethical discussions about their treatment.
  • "Disregard" refers to the action or state of ignoring something or treating it as unworthy of consideration. (उपेक्षा)
  • Example: His disregard for the rules led to serious consequences.
  • Hence, we can infer that the opposite of 'Sentience' is 'Disregard'.

Therefore, the correct answer is: Disregard.

Additional Information

Here are the other options explained along with their Hindi meanings and example sentences:

  • Appreciation (प्रशंसा): Recognition and enjoyment of the good qualities of someone or something.
  • Example: She showed her appreciation for his help by giving him a gift.
  • Consciousness (चेतना): The state of being aware of and able to think and perceive.
  • Example: After the accident, he regained consciousness in the hospital.

    She asked Ravi what is worrying him.

  2. BOption (b)

    She asks Ravi what has worrying him.

  3. COption (c)

    She asks Ravi what is worrying him.

  4. DOption (d)

    She asked Ravi what was worrying him.

View answer & explanation

Correct answer

Answer: (d)D.

She asked Ravi what was worrying him.

Why this answer is correct

Here the correct answer is She asked Ravi what was worrying him.

Key Points:-

  • Let's look at the steps for changing the sentence from direct to indirect speech:
  • As the reporting verb is in the past tense and direct speech is in the present continuous tense, we will take the following steps:-
  • The reporting verb 'said' is changed to 'asked' because 'Reporting verbs such as said/ said to changes to enquired, asked, or demanded'.
  • The conjunction 'that' is not used because 'No conjunction is used, if a sentence in direct speech begins with a question (what/where/when) as the "question-word" itself acts as a joining clause'.
  • For Example:-
  • Direct: “Where do you live?”, asked the boy.
  • Indirect: The boy enquired where I lived.
  • The present continuous tense (are going) is changed to past continuous tense (was going) in the direct speech.
  • The pronoun 'You' is changed to 'him' according to the subject.
  • Thus, the sentence becomes: She asked Ravi what was worrying him.

​

Additional Information

The following table will enable us to know how tense changes in indirect speech:-

Direct SpeechIndirect Speech
Simple Present (Subject + V1 + Object)Simple Past (Subject + V2 + Object)
Present Continuous (Subject + is/am/are + V1 + ing + Object)Past Continuous (Subject + was/were + V1 + ing + Object)
Present Perfect (Subject + has/have + V3 + Object)Past Perfect (Subject + had + V3 + Object)

A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives.

I had seen this road many years ago when my parents moved to Mundakotukurussi, our ancestral village. However, in those early years, I hadn't begun exploring the countryside. I stored the unknown road in my head under 'One Day I Will'. Ten years ago, when I recovered from a herniated disc, it was to discover that I had a useless left leg. Though I managed to lose the limp, I hated not being able to stride around as I used to. I needed a challenge to tell myself that I wasn't going to buckle to a creature called sciatica. Thus the 'One Day I Will' arrived. "Where does the road by the medical shop lead to?" I asked my parents while visiting them next. "Chalavara," they said. "It's not an easy road to walk on," my father added. "There are too many ups and downs." Chalavara was a superior grade of a village as compared to Mundakotukurussi, with a high school, a fine library, ATMs and several shops. But it also has two approach roads. The one I had chosen was a narrow back road used by the locals and that settled it for me. I needed to know for myself I could walk a road that wasn't going to be easy. And the next day, I would get up and walk that road again.

Question 85

What is 'sciatica'?

  1. AOption (a)

    A type of animal

  2. BOption (b)

    Name of a real place

  3. COption (c)

    Name of an imaginary place

  4. DOption (d)

    A herniated disc

View answer & explanation

Correct answer

Answer: (d)D.

A herniated disc

Why this answer is correct

The correct answer is A herniated disc

Key Points

  • From the lines given in the passage: 
  • Ten years ago, when I recovered from a herniated disc, it was to discover that I had a useless left leg
  • I needed a challenge to tell myself that I wasn't going to buckle to a creature called sciatica.
  • Thus, sciatica here refers to herniated disc.

  3. COption (c)

    3

  4. DOption (d)

    4

View answer & explanation

Correct answer

Answer: (a)A.

1

Why this answer is correct

The erroneous part is: 1.

Key Points

  • "climb up" is used to describe the ascent of a mountain or cliff.
  • It is incorrect to state the “climbing upside” because logically the upside of a mountain is a peak or crater which is not “climbed” and instead “walked on”.
  • Hence, 'climb upside' must be replaced by 'climb up'.

Therefore, the correct answer is: The climb up the mountain was not easy.

Question 88

In the following question, out of the four alternatives, select the word similar in meaning to the word given.

Incensed

  1. AOption (a)

    Ecstatic

  3. COption (c)

    Elated

  4. DOption (d)

    Blithe

View answer & explanation

Correct answer

Answer: (b)B.

Exasperated

Why this answer is correct

The correct answer is option 2. i.e. 'Exasperated.'

Key Points

  • ‘Incensed’ means very angry or enraged. (क्रोधित)
  • ‘Exasperated’ means infuriated. (ग़ुस्से में लाना​)
  • ‘Ecstatic’ and ‘elated’ mean very excited and joyful. (परमानंद)
  • ‘Blithe’ means happy or carefree. (प्रसन्नचित)

According to the above-given definitions, ‘exasperated’ is the most similar in meaning to the word ‘incensed’ and hence the correct option.

    Neoteric

  4. DOption (d)

    Virgin

View answer & explanation

Correct answer

Answer: (a)A.

Putrefy

Why this answer is correct

The meaning of 'putrefy' is to decay and produce a fetid smell. 'Crisp' means firm, dry and brittle. 

'Neoteric' means new or modern. 'Virgin' also means similar.

Answer: (b)B.

tacit

Why this answer is correct

It can be clearly apprehended that the blank requires an adjective to clearly explain the succeeding word. Since the options 1 and 4 are adverbs, they can be eliminated as an answer. 

‘Tacit’ and ‘taciturn’ are both adjectives but are different in meaning even though they seem similar. ‘Tacit’ means something understood without even being stated while ‘taciturn’ means inability of a person to speak. Here, according to the context, ’tacit’ is the most appropriate word and hence, the correct option.
