D Correct answer
Explanation

Let shares be 2x, 7x, and 9x for P, Q, and R. The condition states P + Q = R, which means 2x + 7x = 9x, or 9x = 9x. This is always true but doesn't give us the actual value of x. Without the total amount or any specific share value, we cannot determine the difference between P and Q (which would be 7x - 2x = 5x).
