Question
At present, the total of ages of Arjun and Ravi is 60
years. Two years ago, the ratio of their ages was 3:4. What is the current age of Ravi?Solution
ATQ,
Let the present age of Arjun = y years
Then, present age of Ravi = (60 - y) years
According to the question,
(y - 2):(60 - y - 2) = 3:4
⇒ 4(y - 2) = 3(58 - y)
⇒ 4y - 8 = 174 - 3y
⇒ 7y = 182
⇒ y = 182 ÷ 7 = 26
So, present age of Ravi = 60 - 26 = 34 years
