4 days is the right answer. This is how, Let P work at a rate of 1/18, Q at 1/9, and R at 1/12. Therefore, together, they would work at 1/18+1/9+1/12=(2+4+3)/36=9/36=1/4 so they will finish in 4 days.

21 分鐘內	Brett Goosen thegoosefactor	I disagree. In this team who is the manager? Does he delegate or lead by example? Do the other two work well together or will one or both start slacking? How long till the manager fires one or both, or is fired himself? Does he have that authority? How long will HR proceedings delay the project? Are we still working on this? Let's circle back in a month.
