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-----(1) => A – C = 7 ------(2) => A = 7 + C => A + B + C = 33 => 2B + B = 33 => B = 11 Now, => A + B + C = 33 => A + 11 + C = 33 => A + C = 22 ----(3) Soving equation 2 and 3, Age of A = 14.5 Age of C = 7.5 Required ratio = 14.5:11:7.5 = 29:22:15
