D Correct answer
Explanation

Let Q's present age be x years. Then P's present age is 2x years. After 5 years: (2x + 5) + (x + 5) = 70, which gives 3x + 10 = 70, so 3x = 60 and x = 20. Q's present age is 20 years, P's present age is 40 years. The sum of their present ages is 20 + 40 = 60 years. Option D is correct.
