At least 100 students at a certain high school study Japanese. If 4 percent of the students at the school who study French also study Japanese, do more students at the school study French than Japanese?

(1)16 students at the school study both French and Japanese.

(2)10 percent of the students at the school who study Japanese also study French.

key is B

I don't know the difference between the students at the school who study French also study Japanese and the students at the school who study Japanese also study French. Why is the key B?

Thank you!

题目是说一个学校超过100人学习日语，学习法语的人中有4%同时学习日语，问学习

法语是不是比学习日语的人多？

条件（1）16人学习两种语言

    （2）学习日语的人中10%同时学习法语

题目的关键是同时学习两种语言的人，根据条件1只能推出有400人学习法语，但题目不

明确学日语到底多少人，所以无法确定；根据条件2，同时学习两种语言的人占学习日

语的人的10%，而占学法语的人只有4%，显然学法语的人比较多。所以选B。
