11.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] 2
[B] 3
[C] 4
[D] 6
Answer : [A]
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 |
