A certain project is completed within a time limit. Team A works alone and completes it on time. Team B alone completes it 3 days late. Now after two days of cooperation between the two teams, team B will do the rest of the project alone, and it will be completed on time. So how many days is the project deadline?
某工程限期完成，甲队单独做正好按期完成，乙队单独做误期3天才能完成，现在两队合作2天后，余下的工程再由乙队独做，也正好按期完成．那么该工程限期是多少天？
