P and Q are both positive integers

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 + 6), the remainder is also D. If P/Q = 1020.75 and P/(Q + 6) = 816.6, then which of the following gives the correct set of {D, Q}?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
