Question

A and B together can do a work in 25 days. they work to together for 15 days and then B leaves. A finishes the rest of work in 20 days . how many days would each other to complete the work separately

Answer 1

I am guessing 50 Days?

Since the work together takes 25 days and 15 days were done, so A took 20 days to complete work that would have taken 10 days if he had B, Indicating 1 day of working together = 2 days of working seperately
