SSC CHSL - 6 Aug 2021 - Shift 1 • Reasoning • Q95

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

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 2379.

 Understanding 

The logic used here is:

Option 1: 2197

133 = 2197

Option 2: 4913

173 = 2197

Option 3: 1331

113 = 2197

Option 4: 2379

2379 is not a perfect cube.

This does not follow the logic.

Hence, option 4 is the odd one out.
