Q1. A man is 4 times as old as his son. 4 years ago, he was 6 times as old as his son. What is the man's current age?
Answer: 40 years
Explanation: Let's denote the son's current age as x. The man's current age is 4x. 4 years ago, the man's age was 4x - 4 and the son's age was x - 4. So, 4x - 4 = 6(x - 4).
