问题 单项选择题

某商户进了一批货,按照50%的利润定价,结果卖出了40%。此时,该商户发现该商品进价下跌20%,于是又进了第二批货,数量与第一批相同。与此同时,为了资金快速回笼,剩余的货物全部打折销售,并最终获利40%。问后期打折的力度为多少

A.七折
B.八折
C.九折
D.九三折

答案

参考答案:B

解析: 设最初进价为1元,每批货物数量为100,则第一次进货的成本为100元,每个货物的定价为1×(1+50%)=1.5元。售出了100×40%=40个货物,还剩下60个,售出的货款为1.5×40=60元。第二次的进价为1×(1-20%)=0.8元,成本为0.8×100=80元。两次总成本为100+80=180元,故两次售出的总货款为180×(1+40%)=252元,后期卖了252-60=192元,故后来的定价为192÷(100+60)=1.2元,折扣为1.2÷1.5=0.8。

Dear Dr. Fang

      I am a 16-year-old teenager, and I have some problems at home that I hope you can help me with.

     The main problem is that I can't get along with my parents. Whenever I want to do something or suggest

an idea, they don't listen to me. They always make me do things I don't like. Each time I watch a DVD or play

foreign music, he sends me to bed or asks me to play the piano. He even forbids me from chatting with my

friends online.

     I love them a lot but I can't understand them, what should I do? Can you give me some advice?

      Best wishes
