After 6 years, son’s age will be A. 13:4 B. 9:2 C. 5:2 D. 7:3 Answer Workspace Report Discuss Answer with explanation Answer: Option D Explanation Let the age of father and son 10 years ago be 3x and x years respectively. Then, (3x + 10) + 10 = 2[(x + 10) + 10] 3x + 20 = 2x + 40 => x = 20. Required ratio = (3x + 10):(x + 10) = 70:30 = 7:3 Workspace
