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.

条件2的意思是学日语里面有10%也学法语。题目里面有个条件是学法语里面有4%也学日语。就是同一个重复部分占法语的4%,占日语的10%。肯定法语的多。
