Group C Mains 2024 - General Studies & Intelligence Test — Question Paper with Answer Key & Explanations

Correct answer: B

Working through it, option B is the one. Add every region that includes Science — only-Science (19), plus each overlap touching Science — and the total comes to 119, ahead of History (111), Mathematics (102), and Geography (101). In four-set Venns, count each subject by sweeping every zone where its circle appears.

Correct answer: D

Straight to the answer — option D. The gaps between terms grow by 8 each step: 10, 18, 26, 34 — so the next gap is 42 and 90 + 42 = 132. When second differences stay constant, the next term follows by adding that fixed increment to the last gap.

Correct answer: C

The right pick is option C. From the chain — Sham > Ram > Amir and Sudhir > Shishir > Ram — Amir sits below Ram with no one shorter named below him, so Amir is shortest. Line up all five names on one height ladder before picking the extreme.

Correct answer: D

The verified answer here is option D. In each circle the four outer numbers sum to a value whose square fills the centre: 14² = 196, 13² = 169, 16² = 256; for 7 + 6 + 5 + 3 = 21, we get 21² = 441. Spot the repeated squaring rule across the first three figures before solving the fourth.

Correct answer: A

The examiner has marked option A. B's correct share is 3/9 of the total and the wrong share is 2/14; the shortfall is (3/9 − 2/14) = 4/21 of the whole amount, and 4/21 × Total = ₹30,000 gives Total = ₹1,57,500. Ratio-error sums always compare each person's correct fraction with what they actually received.

Correct answer: D

Working through it, option D is the one. At 9 o'clock the minute hand sits at 12; if the hour hand at 9 points west, the whole dial is rotated so that the 12-position faces north. Picture the rotated clock face — where 12 sits fixes the minute hand's direction.
