The total of the ages of Jayaram, Praveen and Sarath is 93 years. Ten years ago, the ratio of their ages was 2 : 3 : 4. What is the present age of Sarath?
Let the ages of Jayaram, Praveen and Sarath 10 years ago be 2x, 3x and 4x years respectively
Then, (2x + 10) + (3x + 10) + (4x + 10) = 93
9x = 63
x = 7
Sarath's present age = (4x + 10) = 38 years.
10 years ago means we should use minus right?
