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

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

[A].

2

[B].

3

[C].

4

[D].

6

Answer: Option C

Explanation:

90 = 10 x 9

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

Now, 653×0 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.
