Answer: Option
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.

3 year ago(h+w+c) = 27 * 3 = 81.
5 year ago=81-6 = 75(2h+2w+2c).
5 year ago(w+c) = 2 * 20 = 40.
5 year ago h = 75-40 = 35.
And the present age is 40 years of the husband.
5 year ago=81-6 = 75(2h+2w+2c).
5 year ago(w+c) = 2 * 20 = 40.
5 year ago h = 75-40 = 35.
And the present age is 40 years of the husband.

The age of mother and father when the child was just born is 24/2=12.
When the child reaches to the age of the mother means when it will reach 12 years,
Father age is 12+12=24.
Can anyone say is this answer is correct?

3 years ago, average age of husband, wife and their child = 27,
=> Sum of age of husband, wife and their child before 3 years = 3 * 27 = 81,
=> (h-3) + (w-3) + (c-3) = 81,
=> h + w + c = 81 + 9 = 90 --- equation(1).
5 years ago, average age of wife and child = 20,
=> Sum of age of wife and child before 5 years = 2 * 20 = 40,
=> (w-5) + (c-5) = 40,
=> w + c = 40 + 10 = 50 --- equation(2).
Substituting equation(2) in equation(1)
=> h + 50 = 90,
=> h = 90 - 50 = 40.
i.e., Present age of the husband = 40.

@ALL.
Members average-years ago=average age.
((h+w+c)/3)-3=27.........=90.
n0w average age of wife and child.
((w+c)/2)-5=20............=50,
So, 90-50=40 years.
