E Correct answer
Explanation

Let father's age = F, son's age = S. First condition: 2S + F = 70. Second condition: 2F + S = 95. Solving these simultaneously: From first, F = 70 - 2S. Substituting in second: 2(70 - 2S) + S = 95 → 140 - 4S + S = 95 → 140 - 3S = 95 → 3S = 45 → S = 15. Then F = 70 - 2(15) = 70 - 30 = 40. Ages are 40 (father) and 15 (son), matching Option E.
