If the number 1005×4 is completely divisible by 8, then the smallest integer in place of x will be

If the number 1005×4 is completely divisible by 8, then the smallest integer in place of x will be:

 (a) 2

(b) 4

(c) 1

(d) 0

Sol:

For any number to be divisible by 8, its last 3 digits must be divisible by 8

By putting x=0 in 1005×4, we see that 504 will be divisible by 8.
