A father is four times as old as his son. In five years, the sum of their ages will be 65. How old is the son now?
Answer and explanation
Correct answer: A. 11 years
- Step 1: Let the son be x and the father 4x. Step 2. Five years later: 5x + 10 = 65, so x = 11. Answer: 11 years. Why not the others: these ages do not give a sum of 65.
