Question

A father's présent age is one year more
than 5 times of his son's age. After 3
years, the father's age would be 2 years
less than four times the son's age. Find
the present age of the father.​

Answer 1

Explanation:

Let the age of son be x.

Thus, age of father is 4x.

After 5 years, their ages will be x+5 and 4x+5 years respectively.

As per the question, we have

4x+5=3(x+5)

⇒4x+5=3x+15

⇒x=10

Age of father will be 4x=4×10=40 years.

Thus when son is 10 years old, father is 40 years.
