(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.

C是解以后你碰到这类百分比的题就设一共100个人（这道题是项目组）好了于是这道题就可以这样理解

（1）25个项目组人数 >=4

（2）35个项目组人数 <=2

所以按从小到大排列的话： 100个数前35个是1或2 后25个是4、5、6…… 中间的只能是一大堆3个人的项目小组于是中数就索3咯

我怎么有点晕？中数的前提时整个数列中的数已经确定，可是本题中employee的人数时没有上限的，跟%没有关系吧？

这题有误。若剩下的40％>10000或=1那该如何解？

哦，懂了，题目以明确了。
