If the integer N = 139,k50 where k is the hundreds digit, N can NEVER be divisible by which of the following?  Pick one
A) 2  B) 3  C) 4  D) 6  E) 9
It is divisible by 2 irrespective of k value as unit digit's value is even(0).   It can be divisible by 3 for k values 2,5,8 as sum will be divisible by 3   It can be divisible by 6 if divisible by 2 and 3.   It can be divisible by 9 for k value 2 as sum will be divisible by 9.   Therefore answer is 4 as number is divisible if last two digits are divisible.In this case 50(No)   Hence answer 4
