问题 A group of workers receives a pay increase of 10%. Also over this same time period the retail price index rises 10 points to 5It can be concluded that real wages have______.

选项 A、risen by approximately 10%
B、risen by approximately 8%
C、fallen by approximately 8%
D、unchanged

答案B

解析 答案为B项。零售物价指数(retail price index,RPI)的上涨说明有通胀发生,通胀率=10/(510—10)=2%。实际收入增加应为名义收入增加减去通胀率,因此,本题之意是工人的实际工资增长率=10%一2%=8%。故本题选B项。
