5.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 scholl who study Japanese also study
French.
Ans:B
做PP做到的，他始终没有提到学French的有几个人或比例，那要怎麽判断是否多或少？
