Question: Father is four times the age of his daughter. If after 5 years, he would be three times of daughter’s age, then further after 5 years, how many times he would be of his daughter’s age?

Solution:
Let the daughter's age be x and father's age be 4x.
So as per question, 4x + 5 = 3(x + 5)
⇒ 4x + 5 = 3x + 15
∴ x = 10.
Hence present age of daughter is 10 years and present age of father is 40 years.
So after 5 + 5 = 10 years, daughter age would be 20 years and father’s age would be 50 years.
Hence father would be 50/20 = 2.5 times of daughter’s age.
