    Solution

    ATQ, Let the present ages of Rahul and Rajat be 7x years and 5x years, respectively. So, the present age of Anirudh = 7x – 3 years Present age of Sneha = 5x + 5 years According to question:  7x + 5x + 7x – 3 + 5x + 5 = 4 × 24.5 24x + 2 = 98 24x = 96 x = 4 So, the present ages of Sneha, Anirudh, Rahul and Rajat are 25 years, 25 years, 28 years and 20 years respectively. So, the desired ratio = 20:25 = 4:5
