Question

Three of the following four are alike in certain way and so form a group. Which is the one that does not belong to that group?
1. 836654
2. 836475
3. 836432
4. 836986

Answer 1

Correct Answer - Option 2 : 836475

The logic is as:

836654 → 8 + 3 + 6 + 6 + 5 + 4 = 32

836475 → 8 + 3 + 6 + 4 + 7 + 5 = 33

836432 → 8 + 3 + 6 + 4 + 3 + 2 = 26

836986 → 8 + 3 + 6 + 9 + 8 + 6 = 40

Here the sum of the digits of all the given options except option (2) is even.

Hence, option (2) is odd one out.
