Question

Three of the following four numbers are alike in a certain way and one is different. Pick the number that is different from the rest.
1. 1727
2. 728
3. 2199
4. 1330

Answer 1

Correct Answer - Option 3 : 2199

Here the logic is ;

I. 1727 = 1727 + 1 = 1728 = 12³

II. 728 = 728 + 1 = 729 = 9³

III. 2199 = 2199 - 2 = 2197 = 13³

IV. 1330 = 1330 + 1 = 1331 = 11³

2199 is different.

Hence, the answer is Option 3, 2199.
