Question

3 years ago the average age of a husband, his wife and his son was 27 years and that of his wife and son 5 years ago was 20 yrs .What is the husband's present age?

Answer 1

Answer:

40 years

Step-by-step explanation:

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.
