Accepted Answer

The sentence starts by stating his birth date is unknown. P logically follows, introducing the belief about his birth month. Q completes the thought about May and his decision, which R then explains with the reason (Everest climb).

Question 3

Select the antonym of adulterate

Accepted Answer

Adulterate means to make something poorer in quality by adding another substance. Therefore, 'purify' which means to remove impurities, is its direct antonym.

Question 4

If 3A = 7B = 13C, then A : B : C is equal to

Accepted Answer

Let 3A = 7B = 13C = k. Then A = k/3, B = k/7, C = k/13. The ratio A:B:C is 1/3 : 1/7 : 1/13. Multiply by LCM of 3, 7, 13 (which is 273) to get 91:39:21.

Question 5

Segment AB is parallel to segment CD. AD intersects BC in  E. If lengths of AE, BC and ED are 10 cm, 15 cm and 15 cm, what is the length of EC?

Accepted Answer

Triangles ABE and DCE are similar due to AB || CD. Thus, AE/ED = BE/EC. Substitute given values: 10/15 = (15-EC)/EC. Solve for EC to get 9 cm.

Question 6

If x + 3 ≤ 4x + 4 and 3(4 - x) - 4 ≥ 2x - 2, then x can take which of the following values?

Accepted Answer

Solve both inequalities: x + 3 ≤ 4x + 4 gives -1 ≤ 3x or x ≥ -1/3. And 3(4 - x) - 4 ≥ 2x - 2 gives 12 - 3x - 4 ≥ 2x - 2, which simplifies to 8 - 3x ≥ 2x - 2, so 10 ≥ 5x or x ≤ 2. Combining, -1/3 ≤ x ≤ 2. The only option in this range is 1.

Question 7

Select the word with the correct spelling.

Accepted Answer

The correct spelling among the given options is 'deviance'. The other words 'humanoide', 'rikshaw', and 'virtuos' are misspelled.

Question 8

Rearrange the parts of the sentence in correct order.Today, less privileged whiteP- Americans are considered to beQ- and pathologists predominatesR- in crisis, and the language of sociologists

Accepted Answer

The sentence starts with 'Today, less privileged white'. P completes this to 'white Americans'. Q follows, 'are considered to be in crisis'. R then completes the thought: 'and the language of sociologists and pathologists predominates'.

Question 9

Select the antonym of fidget

Accepted Answer

Fidget means to make small, restless movements. The antonym is 'composed,' meaning calm and self-possessed, which is the opposite of fidgeting.

Question 10

Rearrange the parts of the sentence in correct order.In punishment for the uprising,P-called tributes, to participateQ-each of the twelve districts must provideR-one girl and one boy,

Accepted Answer

The sentence starts with the introductory phrase. Then, 'each of the twelve districts must provide' (Q) logically follows, specifying who provides what. Finally, 'one girl and one boy, called tributes, to participate' (R then P) completes the thought.

Question 11

Which of the following equations has 3 as a root?

Accepted Answer

Substitute x=3 into each equation. The equation that results in 0 is the correct one. For option 1, 3^2 - 7(3) + 12 = 9 - 21 + 12 = 0.

Question 12

A bank offers 5% compound interest per half year. A customer deposits Rs 8000 each on 1st January and 1st July of a year. At the end of the year, the amount he  would have gained by way of interest is

Accepted Answer

First deposit (Jan 1) earns interest for two half-years: 8000 * (1.05)^2 = 8820. Second deposit (Jul 1) earns interest for one half-year: 8000 * (1.05) = 8400. Total interest = (8820 - 8000) + (8400 - 8000) = 820 + 400 = 1220.

Question 13

In ΔDEF, G and H are points on side DE and DF  respectively. GH is parallel to EF. If G divides DE in the  ratio  3:2 and HF is 8 cm, then the length of DF is

Accepted Answer

By Basic Proportionality Theorem, DG/GE = DH/HF. Given DG:GE = 3:2 and HF = 8 cm. So, DH/8 = 3/2, which means DH = 12 cm. Therefore, DF = DH + HF = 12 + 8 = 20 cm.

Question 14

Select the antonym of vibrant

Accepted Answer

Vibrant means full of energy and life. Drab means lacking brightness or interest, making it the direct opposite. Therefore, 'drab' is the correct antonym.

Question 15

Question 18

Amar is 2 times as good a workman as Badal and therefore is able to finish a job in 15 days less than Badal. In how many days can they together complete the  job?

Accepted Answer

Amar is twice as efficient, so he takes half the time. If the time difference is 15 days, Badal takes 30 days and Amar takes 15 days. Together, they complete it in (30*15)/(30+15) = 10 days.

Question 19

If16qxy=(2x+y)2−(2x−y)2, then what is the value of q?

Accepted Answer

Use the identity (a+b)² - (a-b)² = 4ab. Here, a=2x and b=y. So, (2x+y)² - (2x-y)² = 4(2x)(y) = 8xy. Equating 16qxy = 8xy, we get 16q = 8, thus q = 0.5.

Question 20

Common factor of12a4b6,18a6c2,36a2b2is

Accepted Answer

Find the HCF of the numerical coefficients (12, 18, 36) which is 6. For variables, take the lowest power present in all terms. Thus, HCF is 6a².
