GWD1-35 DS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.
请问哪个是正解? 答案是C,没想通.
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
原来……谢谢!
Thanks!
这题有误。若剩下的40%>10000或=1那该如何解?
