Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 19: 622.

The logic used here is:

(1st number)2 × 2 = 2nd number

Option 1: 12: 288

(12)2 × 2 = 144 × 2 = 288

This follows the logic.

Option 2: 19: 622

(19)2 × 2 = 361 × 2 = 722

This does not follow the logic.

Hence, option 2 is the odd one out.
