Let us assume that when son was born, father's age was x years and son's age was 0 years.
Now, according to father:-
Son's age is x years, which means that father has also grown x years.Now he is 2x years old.
Father is now x years older than his son.
Father's present age=38 years.
ATQ:-
38-x=x
38=x+x
38=2x
38/2=x
19=x
So the present age of son is 19 years.
His age five years back was (19-5) years
=14 years.
