问题 There are five numbers in a list, the first number is less than 4, the second number is between 4 and 5, the third number is 6, the fourth number is between 10 and 20, the fifth number is greater than 20, then which of the following is the median of this list?
选项 A、4
B、5
C、10
D、8
E、6
答案E
解析 这个数列中一共有5个数，那么中数是排序后中间的那个数。现在一个数小于4，一个数在4和5之间，一个数为6，一个数在10和20之间，一个数大于20；那么排序后中间的那个数必然是6，所以选项E为正确答案。
