问题 单项选择题

某房地产开发企业开发一住宅小区,建筑面积为15000平方米,住宅平均售价为1500元/平方米。已知开发费用为:土地总费用200万元;前期工程费350万元;建安工程费1200万元;管理费80万元;税金120万元。采用盈亏平衡分析法对投资进行评估,若正常年份的设计产量为100000平方米,则其经营安全率为()。

A、87.91%

B、88.29%

C、89.84%

D、91.00%

答案

参考答案:C

解析:销售额盈亏平衡点x=固定成本/(平均价格-单位可变成本)=(200+350+80)/(1500-(1200+120)/1.5)=1.016万平米,从而经营安全率=(1-10160/100000)*100%=89.84%

     I'm 14, a year younger than most of my classmates.

     A week ago one of my classmates, Nitin, asked me for help with math homework. We ended up

talking about computers and file-sharing (共享文件). As we talked I found that he was more experienced

and could teach me about file-sharing and networking. We went to his room and watched a movie about

robots that he'd downloaded. The math homework was forgotten.

     The next day he came again for homework help "What do you do on weekends?" he asked. The truth

is, when I have work to do, I do it. I have no special time to kill with friends. I was embarrassed about

this. I expected him to think I was boring and said, "Get a life!" He said, "OK. You're having trouble

getting along with people I can show you. I'm old than you."

     Later, he checked my computer. He even connected me to an Internet chess server (服务器). He was

becoming like a big brother.

     But when I thought about it, I didn't really want Nitin's help" His big-brother idea began to bore me.

     "I'll get you some cool computer programs (程序)".

     "I'll teach you how to talk to girls."

     He meant what he was saying, but I don't know why it didn't make me feel good. Since then he's

hardly talked to me; we seem to have forgotten each other. I don't think he can "teach" me much, and I

don't think much of him. But I could be wrong?
