Q25:
For a certain race, 3 teams were allowed to enter 3 members each. A team
earned 6 – n points whenever one of its members finished in nth place,
where 1<= n <= 5
There were no ties, disqualifications, or withdrawals. If no team earned
more than 6 points, what is the least possible score a team could have earned?
A. 0
B. 1
C. 2
D. 3
E. 4
答案 : D
我的思路是这样
九个人比赛
A B C D E F G H I
名次 1 2 3 4 5 6 7 8 9
得分 5 4 3 2 1 0 0 0 0
所以 只要任意找三个人搭配，一个对伍 最不可能是几分
我搭配到 总分是3的合理压， Ex: AEI; BDH; CFG (CFG 3分)
总分是2 跟总分是1 还有0 就搭配不出来
我的思路不知道这样对吗

1F：推 jennes:全部分数15 有3队,平均得分5-5-5 ... 没有一队超过6分 08/15 18:27
2F：→ jennes:问得分最少的可能..那就是6-6-3的组合..因此3分是最少的 08/15 18:29
3F：推 flac:J大这样的思路最快 08/16 14:22
4F：→ dolphin100:原来我搞错语意啦..XDD 08/17 18:23
