Question
The present ages of Rohit and Mohit are in the ratio 9
: 5, respectively. If 7 years ago from now, the sum of ages of Rohit and Mohit was 42 years, then find the age of Rohit 8 years hence from now.Solution
Let the present ages of Rohit and Mohit be ‘9x’ years and ‘5x’ years, respectively. ATQ : (9x - 7) + (5x - 7) = 42
14x - 14 = 42
14x = 56
x = 4
So, present age of Rohit = (9 x 4 = 36) years So, required age of Rohit = (36 + 8 = 44) years
