估计脑子那里短路了，第一题就搞不出来帮我看看吧

Of the fruit that arrives at a cannery, 20 percent by weight is rejected before processing.  Of the fruit that is processed, 15 percent by weight is rejected before canning.  Of the fruit that arrives at the cannery, what percent by weight is canned?    答案是d

A.       32%

B.       35%

C.       65%

D.       68%

E.        70%

 我是这样子算得， 第一reject后，还剩80%，第二次就是 80% 乘以 75% 最后只剩下 60%。怎么没有答案的。

咳，头昏了。呜呜呜

偶也把100-15减成75了！
