SSC CHSL 2022 PYQ — Question 80

SSC CHSL - 2 June 2022 - Shift 2 • Reasoning • Q80

The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3. i.e. 15: 210.

The logic used here is: 1st number × 2 - 2 = 2nd number

Option 1: 43: 84 → 43 × 2 - 2 = 86 - 2 = 84   This follows the logic.

Option 3: 15: 210 →15 × 2 - 2 = 30 - 2 = 28 This does not follow the logic.
