A Correct answer
Explanation

Let father's current age be F and child's current age be C. Given F = 4C and (F-5) = 9(C-5). Substituting: 4C-5 = 9C-45, which gives 5C = 40, so C = 8 and F = 32. Their sum is 40. This age problem requires solving simultaneous linear equations based on two time points.
