问题
Sixty-eight people are sitting in 20 cars and each car contains at most 4 people. What is the maximum possible number of cars that could contain exactly 1 of the 68 people?
选项
A、2
B、3
C、4
D、8
E、12
答案
C
解析
68个人坐在20辆汽车中,每辆汽车最多可坐4个人,仅坐1个人的车的最大可能数目是多少?
解:本题的正确答案是(C)。要想使仅坐1人的车的数目最多,其他车就应尽可能地多坐人,即其他的车应都坐4个人。设仅坐1人的车的数目为x,则(68-x) / (20-x) =4 → x=4
