Question
Six years from now, the sum of the ages of A and C will
be 84 years. If the ratio of their present ages is 5:3, find the difference between their present ages.Solution
Let the present ages of A and C be 5x and 3x years.
Sum of the present ages = 84 − 12 = 72 years
ATQ,
(5x + 3x) = 72
8x = 72
So, x = 9
So, difference between their present ages = (5x − 3x) = 2x = 18 years
