Let present age of son = x.
The present age of father = 38.
Age of father at time of his son birth = 38-x.
Father age at the time of his son birth = present age of the son,
38 - x = x,
,x = 19
19 - 5 = 14.
The present age of father = 38.
Age of father at time of his son birth = 38-x.
Father age at the time of his son birth = present age of the son,
38 - x = x,
,x = 19
19 - 5 = 14.

The present age of the son = x.
They said the Present age of the son = the Father's age at the time of the son's birthday.
i.e. 38 - x = x.
we get x = 19
a/c to condition,
x- 5= 19-5 = 14 (Answer)

It means father's age at the time of his son's birth is equal to son's age at present.
If we take sons age at present as "x" father's age at his son's birth is also "x".
So, 2x = 38.
x = 19.
If we take sons age at present as "x" father's age at his son's birth is also "x".
So, 2x = 38.
x = 19.

Since "I was as old as you are at the present at the time of your birth= father is twice the son's age". So Son's age is x fathers age is 2x.
2x = 38.
x = 19,
Five years ago = 19-5 = 14 Years.
2x = 38.
x = 19,
Five years ago = 19-5 = 14 Years.

0-------------38
38-----------38+38 i.e.2*38.
From above we can conclude that son's age =father's age/2,
son's age =38/2=19,
hence,age of son before 5 years =19-5=14.
Son's age = 14 yrs.

@All.
Simply the calculation is; (father's present age - sons present age) = father's age at the time of birth.
But father's age at the time of the birth of his son = son's present age.

But father's age at the time of the birth of his son = son's present age.

Can be taken as at the time of son birth father was x year old,
Both increases with like son = 1, father = x+1.
Son = 2, father = x+2.
Now situation is son is x, means father is 2x.

Son = 2, father = x+2.
Now situation is son is x, means father is 2x.

These can be solved by option elimination method we have to see by option which no will be divided by 38 in option 19*2=38. Now subtract by 5 because it has told 5 years ago 19-5=14.

38-x=x means that
after substracting x(son's present age) from 38(father's current age),we will get the fathers age at the time of his son's birth and which was also x.

Let present age of son =x.
At the time birth son = 0 and father = x.
Now, son = x & father= 2x
So 2x= 38
=} x = 19.
5 years ago son was 19-5= 14 years.
At the time birth son = 0 and father = x.
Now, son = x & father= 2x
So 2x= 38
=} x = 19.
5 years ago son was 19-5= 14 years.
