Question

5 years ago, a man was 7 times as old as his son. 5 years hence he will be 3
times as old as his son. Find their present ages.​

Answer 1

Answer:

5 years ago he would have been 35. 7 times older than the Son means the son would have been 35/7 = 5 years old. In, effectively, 10 year time, the son will be 15 (5+10) and the man will be 45 (35+10) which is exactly 3 times the age of the son.
