four years ago ravi was 8 years older than priya. if he is now 3 times as old as she us, find their present age?

Ravi is 3 times the age of Priya

Before 4 years, Ravi was 8 years older than Priya.

their present age

Let Ravi's age be x years and Priya's age be y years.

Ravi is 3 times the age of Priya

⟹ Ravi's age = 3 * Priya's age

⟹ x = 3y -- equation (1)

And,

Before 4 years, Ravi was 8 years older than Priya.

Priya's age before 4 years = (y - 4) years.

Ravi's age before 4 years = (x - 4) years.

According to the above condition,

⟹ x - 4 = y - 4 + 8

Substitute the value of x from equation (1)

⟹ 3y - 4 = y + 4

⟹ 3y - y = 4 + 4

⟹ 2y = 8

⟹ y = 8/2

⟹ y = 4

Substitute the value of y in equation (1).

⟹ x = 3(4)

⟹ x = 12

Therefore,

Present age of Ravi = x = 12 years

Present age of Priya = y = 4 years.

I hope it will help you.
