A Correct answer
Explanation

Let son's age be x, man's age be 2x. (2x + 8) / (x + 8) = 7/4. 8x + 32 = 7x + 56. x = 24.

AI explanation

Let the son's present age be x, making the man's age 2x. Eight years later, the ratio equation is (2x + 8) / (x + 8) = 7/4, which cross-multiplies to 8x + 32 = 7x + 56. Solving for x gives the son's present age as 24 years.
