Question
The ages of A, B and C together are 64 years. B is twice
as old as A and C is 4 years older than A. What is the difference between ages of B and C?Solution
Let A’s age be x years. B’s age = 2x and C’s age = (4 + x) According to question, => x + 2x + (4 + x) = 64 => 4x = 60 => x = 15 B’s age = 2x = 30 years C’s age = 4 + x = 19 years Difference between the ages of B and C = 30 – 19 = 11 years
