Question
Ankit is 3 years younger than Rohit while Rohit is 5 years
younger than Suman. If 5 years from now, the ratio of the age of Ankit and Suman will be 3:4 respectively, then find the present age of Rohit.Solution
ATQ,
Let the present age of Rohit be βxβ years.
Present age of Ankit = βx β 3β years
Present age of Suman = βx + 5β years
According to the question,
(x β 3 + 5)/(x + 5 + 5) = 3/4
Or, (x + 2)/(x + 10) = 3/4
Or, 4(x + 2) = 3(x + 10)
Or, 4x + 8 = 3x + 30
Or, x = 22
So, present age of Rohit = 22 years
