Question
The ages of A, B and C together are 54 years. B is
thrice 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 = 3x and C’s age = (4 + x) According to question, => x + 3x + (4 + x) = 54 => 5x = 50 => x = 10 B’s age = 3x = 30 years C’s age = 4 + x = 14 years Difference between the ages of B and C = 30 – 14 = 16 years
