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%
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
平均工资增长了10%,说明裁掉的都是工资低的那些人。登录 或 注册 后可以参加讨论
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。登录 或 注册 后可以参加讨论
