Question
Four numbers have been given out of which three are
alike in some manner, while one is different. Choose the odd one.Solution
The sum of all the digits of the numbers is '37'. 98659 = 9 + 8 + 6 + 5 + 9 = 37
69478 = 6 + 9 + 4 + 7 + 8 = 34
89489 = 8 + 9 + 4 + 8 + 9 = 37
97948 = 9 + 7 + 9 + 4 + 8 = 37
