When n is divided by 15, the remainder is 6. When n is divided by 12, the quotient is equal to Z, and the remainder is equal to 6. Z must be divisible by which of the following numbers? Answers:
A) 13  B) 14  C) 15  D) 16  E) 17
N = 159 q + 6   N = 12 z + 6   Equating   15 Q + 6 = 12z+6   12z=15q   12z/15 = q   since q is an integer Z must be divisible by 15.   Hence 15
