Question

A and B, working together can finish a peice of work in 6 days, while A alone can do it in 9 days. how much time will B alone take to finish it?​

Answer 1

Step-by-step explanation:

6 days of both A and B finish the work

9 days of only B finishes the work

6A+6B=9B

6A=3B

B works twice as hard (per day) as A

If B takes 9 days alone, then A will require 18 days alone to complete the same work.

I hope this is helpful for you
