Question
Four numbers have been given, out of which three are
alike in a certain way and one is different. Select the one that is different.Solution
The logic followed here is as follows: Sum of digit is even. 5764 → 5 + 7 + 6 + 4 = 22 5844 → 5 + 8 + 4 + 4 = 21 7984 → 7 + 9 + 8 + 4 = 28 7955 → 7 + 9 + 5 + 5 = 26
