Each employee rated A received twice the amount of the raise that was paid to each employee rated C; each employee rated B received 3/2 times the amount of the raise that was paid to each employee rated C.

　　A.$370
　　B.$625
　　C.$740
　　D.$1,250
　　E.$2,500
　　答案：E

Answer 1

翻译的不好
设C人均工资为X，则A人均工资2X，B人均工资3/2X，则
50×2X＋100×3/2X＋150×X＝500000，
得X=1250，
∴A人均工资2500
