Question

Mr Sharma is twice as old as his son after four years four times as old as his son before 9 years what is their present age

Answer 1

Answer:

Mr. Sharma's son's age = 20 years

Mr. Sharma's age = 40 years

Step-by-step explanation:

Let assume that,

Mr.sharma's age = x

Mr.Sharma son's = y

According to the question,

⟹ x = 2y

⟹ (x+4) =4( y-9)

⟹ (x + 4) = 4y - 36

⟹ 2y + 4 = 4y - 36

⟹ 36+4 = 4y -2y

⟹ 40 = 2y

⟹ y = 20

therefore, son's age = 20

father's age = 2(20) = 40
