在CD看到的..
12 current students in chemical department's graduate program had
been in the departments' undergraduate program. The 12 students are
what percent of the number of current students in departments'
graduate program?
1) 200 current students in departments' undergraduate program are
not in department's graduate program .
2) 72 current students in departments' graduate program had not
been in the departments' undergraduate program.
1) 没有用→没问题
2) 得 12/(12+72)=1/7?
CD上的争议好像是说 第二个条件没有锁定在"chemical department"
但是真的要看到那麽细吗？
直觉上departments'指的就是chemical department..
大家觉得呢？谢谢
