If the number 97215 * 6 is completely divisible by 11, then the smallest whole number in place of * will be:

[A]. 3[B]. 2
[C]. 1[D]. 5
[E]. None of these

Answer: Option E

Explanation:

Given number = 97215x6

(6 + 5 + 2 + 9) - (x + 1 + 7) = (14 - x), which must be divisible by 11.

  x = 3

given number=97215x6
then (9+7+2+1+5+x+6)=(30+x), which must be divisible by 11.
then we replace x = 3
