Answer 1

Q:

If x and y are the two digits of the number 653xy such that this number is divisible by 80, then x+y is equal to  ?

A) 5
B) 4
C) 3
D) 2

Answer:   D) 2 

Explanation:

Since 653xy is divisible by 5 as well as 2, so y = 0.

Now, 653x0 must be divisible by 8.

So, 3x0 must be divisible by 8. This happens when x = 2

x + y = (2 + 0) = 2.
