Question
The average age of A, B and C is 30 years, while the
average age of B, A and D is 20 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 = 30 × 3 = 90 years Sum of ages of B, A and D = 20 × 3 = 60 years So, C – D = 90 – 60 = 30 years Let the age of C and D be 5x and 3x years, respectively. 5x – 3x = 30 2x = 30 x = 15 So, age of D = 3x = 45 years.
