Four numbers have been given, out of which three are alike in some manner and one is different. Select the number that is different.
Answer & explanation
Correct answer: option 2
The logic here is
sum of the digits = 17
3437 = 3 + 4 + 3 + 7 = 17
7437 = 7 + 4 + 3 + 7 = 21 (odd)
7415 = 7 + 4 + 1 + 5 = 17
5453 = 5 + 4 + 5 + 3 = 17
