Hari is twice as old as Jhony, who is three years older than Rahul. If Hari’s age is five times Rahul’s age, how old is Johny?

Let the age of Rahul be x years.

Therefore Johny’s age is x + 3 years.

According to the question

Hari’s age = 2(x + 3) (twice old as Johny)

And Hari’s age = 5x (five times Rahul’s age)

Thus 2(x + 3) = 5x

x = 2

Johny’s age = x + 3 = 2 + 3 = 5

Hence, Johny is 5 years old.
