Question

The ratio between the present ages of p and r is 5:3. The ratio between p's age




four years ago and r's age four years hence is 1:1. What is the ratio between p's age 4 years




hence and b's age four years ago?

Answer 1

Answer:

As the ratio of their present ages is 3 : 4 , let their present ages be 3X and 4X.

So, 5 years ago, as the ratio of their ages was 5 : 7, we can write (3x-5) : (4x-5) = 5 : 7. Solving, we get X = 10. Hence, their present ages are 3X = 30 and 4X = 40

Hope this helps you.
