We can say that, Let the present ages of Ram and Raj are 6a years and 7a years, respectively. According to question: (6a + 12)/(7a + 12) = 9/10 60a + 120 = 63a + 108 3a = 12 a = 4 So, the present ages of Ram and Raj are 24 years and 28 years, respectively. Present age of Rakesh = either 28 + 2 = 30 years or 28 – 2 = 26 years. So the present age of Rakesh is either 26 years or 30 years.
