题目全解：(1) 25 percent of the projects at Company Z have 4 or more employees assigned to each project. Not sufficient on its own.
(2) 35 percent of the projects at Company Z have 2 or fewer employees assigned to each project. Not sufficient on its own.
(1)+(2) Since 35% of of the projects have 2 or fewer employees and 25% of the projects have 4 or more employees, then 100%-(25%+35%)=40% of the projects have exactly 3 employees assigned to each of them. So, the median number of employees assigned per project is 3. Sufficient.
