the number of televisions sold annually in Borodia has not changed. However, recent statistics show a drop in the number of television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased. 销售的Sum不变,员工数X降低了,Sum=X×效率y+进口数Z。结论是进口数Z增加了,那就是y没有增加太多,因为X降低了啊,如果y增加了,那么Z是什么结果推不出来;x降低了,如果y没有增加太多,表示前半少了,那么后半就多了啊 -- by 会员 prayer (2009/12/26 15:46:03)
