1说有25％的至少4件 当这条件是无法求出答案的 2说35％最多2件 几样这也求不出 但两个加起来可求 因为剩下40％的人是作3件的

那40%只能是3。假设总共100个project, 35个projects≤2人, 25个projects≥4人，画个数轴表示100个projects，（35,75）这一段只能是3。

结合条件一和条件二，25%+35%=60%，25%的是4个或以上的employees，35%的是2个或以下的employees，剩下的40%加上35%=75%大于50%是3个或以下的也就是median其实就是3

35 percent of the numbers are 2 or less and (35 + 40) percent= 75 percent are 3 or less, and hence the median is 3.
