Odd One Out/Classification

Question:

Three of the following four number-pairs are alike in a certain way and one is different. Find the odd one out.

Options:

18 : 306

63 : 3906

15 : 210

37 : 1331

Correct Answer:

37 : 1331

Explanation:

The logic followed here Is :

(Ist number)² - ist number = second number

18 : 306 = 18²+ 18 = 306

63 : 3906 = 63²- 63 = 3906

15 : 210 = 15²- 15 = 210

37 : 1331 = 37²- 37 = 1332 ≠ 1331
