he ages of A and B are presently in the ratio of 3:5. Nine years ago this ratio will become 12:23. What is the present age of A?
Question
Solution 1
Let's solve this step by step:
Step 1: Let's assume the present age of A is 3x and the present age of B is 5x.
Step 2: According to the problem, nine years ago, the ratio of their ages was 12:23. So, we can write this as (3x - 9) / (5x - 9) = 12/23.
Step 3: Cross-multiplying gives us 23*(3x - 9) Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
