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

Suppose the age of son is P years
Therefore, the age of father will be 5P + 1
According to question ,
∴ 4( age of son + 3 ) – 2 years = age of father + 3 years
⇒ 4 ( P + 3 ) – 2 = ( 5P + 1 ) + 3
⇒ 4P + 12 – 2 = 5P + 4
⇒ 10 – 4 = 5P – 4P
∴ P = 6
Age of father = 5P + 1 = 5 × 6 + 1 = 31 years
Hence , the age of father is 31 years .
