Ten years ago A was half of B of age if the ratio of their present ages is 3: 4. What will be the total of their present ages? A. 8 B. 20 C. 45 D. 35 Answer Workspace Report Discuss Answer with explanation Answer: Option D Explanation Let A’s age 10 years ago = x years. Then, B’s age 10 years ago = 2x years. (x + 10) / (2x+ 10) = 3/4 => x = 5. So, the total of their present ages =(x + 10 + 2x + 10) = (3x + 20) = 35 years. Workspace
