Question
If the total ages of A and B is 6 years more than the
total age of B and C. C is how many years younger than A?Solution
Let the age of A, B and C be x, y and z respectively. Then, according to question, => (x + y) β (y + z) = 6 => x + y β y - z = 6 => x - z = 6 Thus, C is 6 years younger than A.
