Let the present ages of Rahul and Ritesh are 7x years and 3x years respectively. Age of Ritesh three years ago = 3x – 3 years Age of Ramesh three years ago = 3 × (3x – 3) = 9x – 9 years Present age of Ramesh = 9x – 9 + 3 = 9x – 6 years According to question: 9x – 6 – 7x = 6 2x = 12 x = 6 So, the present ages of Rahul, Ritesh and Ramesh are 42 years, 18 years and 48, years respectively. Present average age of Rahul, Ritesh and Ramesh = (42 + 18 + 48)/3 = 36 years
