D Correct answer
Explanation

Let the present age of A be 3x years and that of B be 5x years. 10 years ago, A's age = 3x -10 and B's age = 5x - 10 years Now, according to question, 3x - 10 = 1/5(5x - 10) After solving this equation, we get x = 4 So, sum of ages of A and B = 3 x 4 + 5 x 4 = 32 years
