Question
The current ages of Ashwin and Bhavin are in a 5:4
ratio. Chetan's current age is 25% greater than Bhavin's. If the current average age of Ashwin, Bhavin, and Chetan is 28 years, what is Chetan's present age?Solution
ATQ, Let Ashwin = A, Bhavin = B, Chetan = C A : B = 5 : 4 => A = 5x, B = 4x C is 25% more than B => C = 1.25B => C = 1.25 × 4x = 5x Average age = 28 => (A + B + C)/3 = 28 => A + B + C = 84 => 5x + 4x + 5x = 84 => 14x = 84 => x = 6 C = 5x = 5 × 6 = 30 years
