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)的敘述和題目的敘述4 percent of the students at the school who study French

also study Japanese 怎麼感覺在講一樣的族群, 可是比例不同阿？


拜託各位教教我～～～～謝謝你！！！

推 kcg:的確是一樣的族群，%數不同是因為母體也不同阿...
→ kcg:所以10%的Japanese = 4%的French   這樣
→ Diablotin:謝謝我懂了！
