The average age of A, B and C is 25 years, while the
average age of B, A and D is 23 years. If the ratio of the age of C and D is 5:3, respectively, then find the age of D.Solution
Sum of ages of A, B and C = 25 × 3 = 75 years Sum of ages of B, A and D = 23 × 3 = 69 years So, C – D = 75 – 69 = 6 years Let the age of C and D be 5x and 3x years, respectively. 5x – 3x = 6 2x = 6 x = 3 So, age of D = 3x = 9 years.
