Question

Rahul's father's age is thrice the age of Rahul After 15 years he will be twice the age of Rahul.
Find their current age.

Answer 1

Let the present age of Rahul be a
His father's present age = 3a

After 15 years
Rahul's age = a+15
Rahul's father's age = 3a + 15

According to question
3a+ 15 = 2(a+15)
=> 3a +15 = 2a + 30
=> a = 15

Rahul's present age = 15 years
Rahul's father's present age = 45 years
