Four years ago, the age of person 'A' was three times
the age of person 'B'. Eight years from now, the age of person 'A' will be 24 years more than the age of person 'B'. What is the current ratio of the ages of 'A' to 'B'?Solution
Let the age of ‘B’ 4 years ago from now be ‘x’ years Therefore, age of ‘A’ 4 years ago from now = 3x years According to the question, 3x – x = 24 Or, x = 24/2 = 12 Therefore, required ratio = (3x + 4):(x + 4) = 40:16 = 5:2
