48、the percentage of the teachers who participate in a workshop is 60%, some teachers are teaching arts. what is the percentage of those arts teacher among all people attending workshop?
1)there are 200 people attending
2)among those teachers,there are 72% teacher that don't teach art
【确定】B
我的理解：
总数的60%参加了workshop, 有一些teachers是教文科的，问所有参加workshop的教师中有多少percentage是教文科的？
哦，是否除了arts，就是science？可还是不对呀。。。
B中的those teachers指什么？如果是total teachers，怎么知道结果？
What is the relationship between the teachers who don't teach art and the teachers who participate in the workshop?
是不是我理解错了？

我也觉得如果是指teachers who attend workshop就太简单了，
那么题目还给那么多条件做什么？作者: tongxun 时间: 2002-9-19 09:07
可能是用来鉴定条件1）成不成立吧。作者: cook 时间: 2002-9-19 12:09
B. FYI: 参加了workshop的teachers 占attending people总数的60%, some teachers是教文科的，问所有教文科的teachers 占 attending people 的percentage是？作者: workhard77 时间: 2002-9-20 08:45
1) FYI是什么意思？
2）attending people 哪里来的？
谢谢！作者: cook 时间: 2002-9-20 11:55
