Question
Currently, the combined age of Rajesh and Ramesh is 77
years. One year ago, the ratio of their ages was 7:8, with Rajesh being 7 parts and Ramesh being 8 parts. What is Ramesh's present age?Solution
Let the present age of Rajesh = 'y' years Then, present age of Ramesh = (77 - y) years According to the question, (y - 1):(77 - y - 1) = 7:8 Or, 8y - 8 = 532 - 7y Or, 15y = 540 So, y = 540 ÷ 15 = 36 So, present age of Ramesh = 77 - 36 = 41 years
