On July 1 of lastyear, the total number of employees at Company E was decreased by 10percent. Without any change in thesalaries of the remaining employees, the average (arithmetic mean) employeesalary was 10 percent more after the decrease in number of employees thanbefore the decrease. The total of thecombined salaries of all of the employees at Company E after July 1 last yearwas what percent of that before July 1 last year?
90%
99%
100%
101%
110%
以前员工数e,减少后是0.9e,以前e个员工总工资是s1,现在0.9个员工总工资是s2
减少员工后,平均工资s2/0.9e比减少前的平均工资s1/e多了10%,s2/0.9e=s1/e*1.1
则s2=s1*0.99
不是说工资不变吗?为什么又有个10%增长,这不是矛盾吗。。。
平均工资增长了10%,说明裁掉的都是工资低的那些人。

假设原来是100人,平均薪水X元/人,现在是90人,平均是1.1X元/人,这样算就是99%。不知道这样理解对不对。
不明白这一句: Without any change in thesalaries of the remaining employees的目的是什么
就是剩下员工的工资没变(七月以后没涨工资,也没减工资)呗。变了的话就算不出来啦。

我又算了一遍平均工资,选的90%,大无语了,算回去了又
问的是总工资,不是平均工资(废话平均工资高多少告诉你了阿)
