Let the present ages of 'A', 'B' and 'C' be '7x', '2x' and '3x' years, respectively. Average of present ages = {7x + 2x + 3x} ÷ 3 = '4x' years ATQ; {(7x - 8) + (2x - 8) + (3x - 8) } ÷ 3 = 28 Or, 12x - 24 = 28 X 3 Or, 12x = 84 + 24 So, 'x' = (108/12) = 9 Therefore, age of 'B' 4 years hence from now = (2x + 4) years = 2 x 9 + 4 = 22 years
