A and B working together can complete the work in 24/7 days, if A had worked 100% more efficiently,the work would have been completed in 12/5 days. How many days does B alone take to complete the work?

Question

Suri Gangula · Accepted Answer

1/A + 1/B = 7/24

2/A + 1/B = 5/12

Solving them you would get 1/A = 3/24

1/B = 1/6

So B takes 6 days
