D Correct answer
Explanation

Let R be Ram's age, F be father's age. F = 8R. (R+6) = (1/5)(F+6). 5(R+6) = 8R+6 => 5R+30 = 8R+6 => 3R = 24 => R = 8. F = 8*8 = 64.

AI explanation

Let Ram's present age be x years, so his father's present age is 8x years. In six years, their ages will be x + 6 and 8x + 6, giving the equation x + 6 = (1/5)(8x + 6). Multiplying by 5 gives 5x + 30 = 8x + 6, meaning 3x = 24 and x = 8. Therefore, Ram is 8 years old and his father is 64 years old.
