Q6 of 46 Page 156

Prakruthi’s age is 6 times Sahil’s age. After 15 years Prakruthi will be 3 times as old as Sahil. Find their age.

Let Age of Sahil be x. ⇒ Age of Prakruthi is 6x


After 15 years, x + 15 & 6x + 15 are their ages


⇒ 6x + 15 = 3 ( x + 15)


⇒ 6x + 15 = 3x + 45


⇒ 3x = 30


⇒ x = 10


The Present ages of Sahil and Prakruthi are 10 and 60 respectively.
