We can say that present ages of 'Aman' and 'Bhanu' be '2a' years and '5a' years, respectively Let present age of 'Chinky' be 'c' years ATQ; (5a + y) = 2 × (2a + y) Or, 5a + y = 4a + 2y Or, y = a Also, (5a - y) = 2 × (c - y) Or, 5a - a = 2c - 2a Or, c = 3a Since, '2' is the only prime number whose cube is even So, difference between present ages of 'Aman' and 'Chinky' = 8 years So, 3a - 2a = 8 Or, a = 8 So, sum of present age of 'Aman' and 'Chinky' = 2a + 3a = 5a = 5 × 8 = 40 years
