Three of the following four numbers are alike in a certain way and one is different. Pick the number that is different from the rest.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 323

Understanding

323: 3 + 2 + 3 = 8

353: 3 + 5 + 3 = 11

313: 3 + 1 + 3 = 7

373: 3 + 7 + 3 = 13

11, 7, and 13 are prime numbers.

So, 323 is the odd one.

Hence, the correct answer is 323.
