Question
The ages of A, B and C are in the ratio 4:6:7 and the
sum of their ages is 85. Find the ratio of 15 years ago B’s age to C’s age after 15 years.Solution
Let the present age of A, B and C be 4x, 6x and 7x respectively. According to the question, => A + B + C = 85 => 4x + 6x + 7x = 85 => x = 5 B’s age 15 years ago = 6x – 15 = 30 – 15 = 15 C’s age after 15 years = 7x + 15 = 35 + 15 = 50 Required ratio = 15 : 50 = 3:10
