Question
The average age of A, B and C is 25 years, while the
average age of B, A and D is 21 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 = 21 × 3 = 63 years So, C – D = 75 – 63 = 12 years Let the age of C and D be 5x and 3x years, respectively. 5x – 3x = 12 2x = 12 x = 6 So, age of D = 3x = 18 years.
