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 7 years. If their sum of age is 33, then find the ratio of ages of three people.Solution
According to question, => A – B = B – C => A + C = 2B => A – C = 7 => A = 7 + C => A + B + C = 33 => 2B + B = 33 => B = 11 Now, => A + B + C = 33 => C + 7 + 11 + C = 33 => 2C = 18 => C = 9 Age of A = 9 + 7 = 16 Required ratio = 16:11:9
