The median of five different positive integers is 12, which of the following is the least possible sum of these five positive integers?
选项
A、38
B、21
C、42
D、54
E、60
答案
C
解析
5个不同正整数的中数是12,那么这5个数排序后中间那个数就是12,另外必然还有两个数大于中数12,两个数小于中数12,现在要求5个数和的最小值。那么大于12的两个正整数要尽可能的小,则为13,14;小于12的两个正整数也要尽可能的小,则为1,2。1+2+12+13+14=42,C为正确答案。
