E车间工人的调入D车间后都是30人，那么E车间原来有：30÷（1-）=36（人），这之前D车间原来有：30-36×=24（人）；D车间工人的调入C车间，这时D车间有24人，C车间有30人，那么D车间原来有：24÷（1-）=32（人），这之前C车间有：30-32×=22（人）；C车间工人的调入B车间，这时C车间有22人，B车间有30人，那么原来C车间有：22÷（1-）=33（人）这之前B车间有30-33×=19（人）；把B车间工人的调入A车间，这时A车间有30人，B车间有19人，那么原来B车间有19÷（1-）=38（人）；原来A车间有30-38×=11（人）．答：原来A车间有11人，B车间有38人，C车间有33人，D车间有32人，E车间有36人．
为您推荐：
最后每个车间都是30人，逆着调入的顺序，从哪个车间调出，这个车间调出之前的人数就是单位“1”，由此根据分数乘除法的意义，逐步求出原来的状态．
本题考点：
逆推问题．
考点点评：
解决本题关键是分清楚各个分率的单位“1”都是谁，然后逆着调动的顺序逐步找出各车间原来的人数．

试题分析：短文大意：这段对话主要描述了鲍勃和爱丽丝初次见面相互问候的一段场景。小题1:根据下文，是的，我是。联系下文Yes, I am Alice.可知选项中Are you Bob? 符合题意，你是鲍勃吗？
小题2:根据下文，是的，我是爱丽丝。可知选项中Are you Alice? 符合题意，你是爱丽丝。
小题3:根据上文，很高兴见到你。可知此处也应该表示很高兴见到你。故填Nice to meet you, too. 也很高兴见到你。小题4:根据下文，当然了，J-A-C-K-E-T 可知上文问的是，你能拼写“jacket“吗？故填：Can you spell “jacket”?
小题5:根据下文答语，是的，这是我的夹克。可知上文问的是，这是你的夹克吗？故答：Is this your jacket?知识点:&&基础试题拔高试题热门知识点最新试题
