When n is divided by 18, the remainder is 6. When n is divided by 11, the quotient is equal to Z, and the remainder is equal to 6. Z must be divisible by which of the following numbers?
Choices
A) 16  B) 17  C) 18  D) 19  E) 20
N = 18 q + 6   N = 11 z + 6   Equating   18 Q + 6 = 11z+6   11z=18q   11z/18 = q   since q is an integer Z must be divisible by 18.   Hence 18
