一道数学

scholar

Each person on a committee with 40 members voted for exactly one of 3 candidates , F, G or H . Did F receive the most votes from the 40 votes cast?

(1)F received 11 of the votes

（2）H received 14 of the votes
答案选A

eemmily

a是对的，40-11=29 29/2=14.5 大于11就是说无论如何都有一个人得票数高于11 所以a可以

讲的再细点 没看明白 谢谢！

a.
40－11＝29，29÷2＝14.5>11，也就是说在G和H两个人之中至少有一个人的票数会大于14.5票，也即是大于11票，故F一定不是最多票者。
所以a的条件充分，足够判断Did F receive the most votes from the 40 votes cast?（判断的结果是no）

b.
这个明显不充分吧。。。
