A father said to his son,I was as old as you are at the present at the time of your birth.If the father's age is 38 years now,the son's age five years back was

Let's denote the son's current age as "S" and the father's current age as "F."

From the information given, we have two statements:

"I was as old as you are at the present at the time of your birth." This means that when the son was born, the father's age was equal to the son's current age. So, when the son was born, the father's age was S.

"If the father's age is 38 years now." This tells us the father's current age, which is 38 years, F = 38.

Now, let's calculate the son's age five years back:

Son's current age (S) - 5 years = Son's age five years back

S - 5 = ?

We know that the father's age at the time of the son's birth was S, and the father's current age is 38. Therefore, the son's age at the time of his birth was 38 - S.

Now, using the information from statement 1:

Son's age at the time of his birth = Father's age at the time of the son's birth

38 - S = S

Now, solve for S:

2S = 38

S = 38 / 2

S = 19

So, the son's current age is 19 years. Now, let's calculate the son's age five years back:

Son's age five years back = 19 - 5 = 14 years.

Therefore, the son's age five years back was 14 years.
