Question
After 12 years, "Aman" will be three times as old as he
was 20 years ago. The age difference between "Aman" and "Bhanu" in twelve years will be 4:5, respectively. Determine the current age of "Chetna" if the average age of "Aman," "Bhanu," and "Chetna" is 38 years old.Solution
ATQ, Let present age of ‘Aman’ be ‘a’ years So, 3(a – 20) = a + 12 Or, 3a – 60 = a + 12 Or, 2a = 72 Or, a = 36 Present age of ‘Bhanu’ = 5/4 × {36 + 12} – 12 = 60 – 12 = 48 years Present age of ‘Chetna’ = 38 × 3 – 36 – 48 = 30 years
