Question

If the number 653 xy is divisible by 90, then (x + y) = ?

Options:

A . 2

B . 3

C . 4

D . 6

Answer: Option C

90 = 10 x 9

Clearly, 653xy is divisible by 10, so y = 0

Now, 653x0 is divisible by 9.

So, (6 + 5 + 3 + x + 0) = (14 + x) is divisible by 9. So, x = 4.

Hence, (x + y) = (4 + 0) = 4.
