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.

Thanks for providing the easiest solution @Loverboy.
3 years ago, their avg is 27.
((h-3) + (w-3) + (c-3) ) /3 = 27.
h+w+c = 90. (present).
5 years ago w & c is 20.
((w-5) + (c-5) ) /2 = 20.
w+c=50. (present).
(h+w+c) - (w+c) = 40.
h = 40 years.

(h+w+c) - (w+c) = 40.
h = 40 years.

@All.
Take x, y, z intial age is 27 after three years it converted into 30. For three members it is 90.
Then 5 years back 20 years. Calculate with present age it is 25.
Now
X+Y+Z=(3*30)=90.
Y+Z=20(5 years back)Now =(25*2)=50,
Now equate it.
Y+Z cancelled,
X=90-50.
And X=40.

@Bharani.
Instead of addition W+C you can replace it by H+C.
i.e (H+W+C)-(H+C).
