问题 In a class of 120 students, 60 percent can speak French and the rest can speak only English. If 25 percent of those in the class who can speak French can also speak English, how many of the students in the class can speak English?

选项 A、54
B、60
C、66
D、84
E、90

答案 C

解析说英语的人=仅仅说英语的人+既能说英语又能说法语的人=40％×120+120×60％×25％=66，所以答案为C。
