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.
