Q1. A man is 4 times as old as his son. In 16 years, he will be twice as old as his son. What is the man's current age?
Answer: 32
Explanation: Let's denote man's age as M and son's age as S. M = 4S. In 16 years: M + 16 = 2(S + 16). Substituting M = 4S, we get 4S + 16 = 2S + 32, so 2S = 16, S = 8, and M = 32.
