Correct Question : The age of the father 3 years ago was 7 times the age of his son. At present, the father’s age is five times that of his son. What are the present ages of the father and the son?

Answer:

Let the present age son be x years and present age of father be 5x years.

❏ According to Question now,

➳ 7(x - 3) = 5x - 3

➳ 7x - 21 = 5x - 3

➳ 7x - 5x = -3 + 21

➳ 2x = 18

➳ x = 18/2

➳ x = 9 years

⬤ Therefore,

Present age of son = x = 9 years

Present age of father = 5x = 45 years.
