Question
The ages of A, B and C are in the ratio 6:7:8 and the
sum of their ages is 63. Find the ratio of 12 years ago B’s age to C’s age after 12 years.Solution
Let the present age of A, B and C be 6x, 7x and 8x respectively. According to the question, => A + B + C = 63 => 6x + 7x + 8x = 63 => x = 3 B’s age 12 years ago = 7x – 12 = 21 – 12 = 9 C’s age after 12 years = 8x + 12 = 24 + 12 = 36 Required ratio = 9 : 36 = 1:4
