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.
(2)的叙述和题目的叙述4 percent of the students at the school who study French
also study Japanese 怎麽感觉在讲一样的族群, 可是比例不同阿？
拜托各位教教我～～～～谢谢你！！！
