A and B can complete a project in 30 days if they work together. B completes the remaining job in 44 days after A has worked for 16 days. In how many days will B be able to complete the entire project on his own?
A. 30 days B. 40 days C. 60 days D. 70 days
Explanation: Let A's one-day work be x and B's one-day work be y.Then 16x + 44y = 1 and x + y = 1/30.We get x = 1/60 and y = 1/60 by solving these two equations.1 day's work for B Equals 1/60.As a result, B will complete the entire project in 60 days on his own.
