5 years age child and wife Avg age was 20, so 3 years ago it was 22.
There we find (27 * 3) - (22 + 22) = 37; 37 is the husbands age 3 years ago,
So present year age => 37 + 3 = 40.
There we find (27 * 3) - (22 + 22) = 37; 37 is the husbands age 3 years ago,
So present year age => 37 + 3 = 40.

Please clarify my doubt. If my age is 10 before 3 years then at present my age should be 13. So it is (10+3) not (10-3) right. But why we subtracted 3 in above question?
