How many of the inventoried textbooks were purchased by the two schools combined during the years 1974, 1975, and 1976? [br] If School X purchased 300 textbooks in 1971 and all of these textbooks either were counted in the inventory or had been discarded before the inventory, what percent of these textbooks had been discarded?
选项
A、10%
B、20%
C、50%
D、80%
E、100%
答案
C
解析
若学校X在1971年购买了300本教科书,且所有的这些教科书或者进入库存或者在进入库存前被废弃,那么被废弃的教科书占这些书的百分之几?
解:本题的正确答案是(C)。1971年学校X库存图书数目为:1500×10%=150;所以被废弃图书所占的百分比为:(300-150)÷300=50%
