朋友刚发给我的, 实在搞不懂,

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

1) 25% of projects at Company Z have 4or more employee assin to each project.
2) 35% of projects at company z have 2or fewer employees assigned to each project.

答案为D.... 各位帮忙解释一下...

我觉得应该是C
25%>=4,
35%<=2,
=> 40%=3，也就是第50%个＝3
