IBPS Clerk Prelims Model Paper 17

Let present age of Ravi be x.
∴ Present age of Ravi’s father = 4x
According to question,
5 years before,
Ravi’s father age = 7 x Ravi’s age
4x - 5 = 7(x - 5)
⇒ 4x -5 = 7x - 35
⇒ 3x=30
∴ x = 10
∴ Ravi’s present age x = 10 years
Ravi’s father’s present age = 4 x 10
= 40 years
