P and Q are both positive integers. When P is divided by Q, the remainder is some positive integer D, and when P is divided by (Q + 5), the remainder is also D. If P/Q = 1020.75 and P/(Q + 5) = 816.6, then which of the following gives the correct set of {D, Q}?  Select the correct option:
A) {6, 12}	B) {6, 15}	C) {15,20}	D) {9, 15}	E) {15, 24}
p/q= d=p/q+5   d= .75 q   d= .6(q+5)   we get d = 15 and q = 20. Answer = {15,20}.
