If the number 7x86038 is exactly divisible by 11, then the smallest whole number in place of x ?

A. 1

B. 2

C. 3

D. 4

**Answer : **C. 3

## Explanation:

The given number = 7×86038

Sum of the odd places = 8 + 0 + 8 + 7 = 23

Sum of the even places = 3 + 6 + x

(Sum of the odd places) - (Sum of even places) = Number (exactly divisible by 11)

23 - (9 + x) = divisible by 11

14 – x = divisible by 11.

X must be 3, to make given number divisible by 11.
