Odd One Out/Classification

Question:

Four pairs of numbers have been given, out of which three are alike in some manner, while one is different. Choose out the odd one.

Options:

18 - 81

26 - 168

16 - 64

34 - 289

Correct Answer:

26 - 168

Explanation:

THE LOGIC;

1) 18 - 81,

9 x2 = 18, 9 x9 = 81

2) 26 - 168,

13 x2 = 26, 13 x13 = 169 not 168

3) 16 - 64,

8 x2 = 16, 8 x8 = 64

4) 34 - 289,

17 x = 34, 17 x17 = 89

Thus, 26 - 168 is the odd one.
