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.

OA:B
对于题目给的条件和问题有很大的疑惑： If 4 percent of the students at the school who study French also study Japanese和10 percent of the students at the school who study Japanese also study French.在数量上会有区别吗，就相当于番茄炒鸡蛋还是鸡蛋炒番茄的问题，这样表述真的很无语。学法语的人学日语和学日语的人学法语，不是一回事吗？

当然不是一样的啦，这个是只是说学法语的人里面有4%也学日语，但是我们并不知道这些人占学日语的总人数的比例，所以做数学题目的时候，一定要绕清楚这个逻辑关系的
