SSC CGL - 18 Aug 2021 - Shift 1 • Reasoning • Q85

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: B

Explanation

The correct answer is option 2 i.e. 324335: 577.

The logic used here is:

The Sum of digits on the left side is equal to the sum of digits on the right side.

Option 1: 253471: 778

2 + 5 + 3 + 4 + 7 + 1 = 22

7 + 7 + 8 = 22

This follows the logic.

Option 2: 324335: 577

3 + 2 + 4 + 3 + 3 + 5 = 20

5 + 7 + 7 = 19

This does not follow the logic.

Hence, option 2 is the odd one out.
