Find the odd pair of numbers from the given options.1-8, 3-22, 7-50, 9-651. 7-502. 3-223. 9-654. 1-8

Answer» Correct Answer - Option 3 : 9-65

The logic is:

1. 7 - 50 → 7 × 7 + 1 = 49 + 1 = 50

2. 3 - 22 → 3 × 7 + 1 = 21 + 1 = 22

3. 9 - 65 → 9 × 7 + 1 = 63 + 1 = 64 ≠ 65

4. 1 - 8 → 1 × 7 + 1 = 7 + 1 = 8

Hence, ‘9 - 65’ is the odd one out.
