Question

The husband and wife summed the age of their two sons 3 years ago to 80 years. So what happens after 3 years?​

Answer 1

Answer:

Sum of the present ages of husband, wife and child = (27 x 3 + 3 x 3) years = 90 years.

Sum of the present ages of wife and child = (20 x 2 + 5 x 2) years = 50 years.

Husband's present age = (90 - 50) years = 40 years.
