SSC CGL - 24 Aug 2021 - Shift 1 • Reasoning • Q97

Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the number pair that is different.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 27: 82.

The logic used here is:

1st number × 6 - 5 = 2nd number

Option 1: 28: 163

28 × 6 - 5 = 163

This follows the logic.

Option 2: 16: 91

16 × 6 - 5 = 91

This follows the logic.

Option 3: 27: 82

27 × 6 - 5 = 157

This does not follow the logic.

Hence, option 3 is the odd one out.
