PREP破解里math1的23题

木了~ 请帮忙解答, 谢谢！

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.

对就是B啊
估计楼主原题没看明白，至少100人在某高中学日语，如果学法语的里面

有4%也同时学日语，问学法语的同学是不是比学日语的更多？
1.16个人同时学习两种语言
2.学日语同学中有10%也同时学习法语
显而易见啊
