Question
Difference between the ages of A and B is same as the
difference between the ages of B and C. The difference between the ages of A and C is 6 years. If their sum of age is 30, then find the ratio of ages of three people.Solution
According to question, => A – B = B – C => A + C = 2B => A – C = 6 => A = 6 + C => A + B + C = 30 => 2B + B = 30 => B = 10 Now, => A + B + C = 42 => C + 6 + 10 + C = 30 => 2C = 14 => C = 7 Age of A = 6 + 7 = 13 Required ratio = 13:10:7
