Question
At present, the total age of Sohan and Rohan is 60 years.
Five years back, the ratio of their ages was 2:3. What is Rohan’s current age?Solution
ATQ,
Let the present age of Sohan = y years
Then, present age of Rohan = (60 - y) years
According to the question,
(y - 5):(60 - y - 5) = 2:3
⇒ 3(y - 5) = 2(55 - y)
⇒ 3y - 15 = 110 - 2y
⇒ 5y = 125
⇒ y = 125 ÷ 5 = 25
So, present age of Rohan = 60 - 25 = 35 years
