Q. If a number is exactly divisible by 11 and 13, which of the following types the number must be?

(A) Divisible by (11 + 13)
(B) Divisible by (13 - 11)

Correct Answer - Option(C)

Explanation by: Mahesh Chandra

LCM of 11 and 13 will be (11 x 13). Hence, if a number is exactly divisible by 11 x 13, then the same number must be exactly divisible by their LCM or by (11 x 13).
