Question:

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.

Options:

4 : 70

7 : 349

3 : 30

8 : 518

Correct Answer:

3 : 30

Explanation:

The logic followed here is:

4 : 70 = 4³ + 6 = 70

7 : 349 = 7³ + 6 = 349

3 : 30 = 3³ + 6 = 33 ≠ 30 (odd)

8 : 512 = 8³ + 6 = 512
