请教一道数学题

What is the median number of employees assigned per project for the projects at Company Z?

(1)   25 percent of the projects at Company Z have 4 or more employees assigned to each project.

(2)   35 percent of the projects at Company Z have 2 or fewer employees assigned to each project.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

答案选d， 请问为什么，谢谢

请问为什么选c阿，怎么能推出结果呢

排序之后，

2人以下的是35 percent －－－条件1

2人以下的是35 percent －－－条件1

3人的是40percent －－－条件1.2联合得出

4人以上是25 percent －－条件2

median是1/2处，也就是3人，条件1.2联合得证
