B.

B+c+D= 69

Now, evenif you make everything 21 (which is A) themax value is 63 hence A did not receive maximum votes. I remember seeing this question somewhere

Can some one explain in littel more detail.

How did we come to the conluciosn that each could have received 21 votes. Is't there a possibility that one memebr received 0 votes, then what happens

We don't know what each one got. But we want to know if A got the most, when there are 90 votes to go around. Number two says that A got 21, which leaves 69 votes for the other three candidates. With that many votes, someone in the other three has to be higher than 21, if not all of them, so the answer is no, which is an answer.

So the answer's B.

Let's see if I got this straight. [#permalink] New post 15 Jul 2004, 10:47
Ok, so here is what I understand from what you guys are saying.

We know A=21
We therefore know B+C+D=69

The question never states how they could have voted.
Consequently, we could have seen a multitude of possibilities for B+C+D
For example,

1+1+67=69 ---> one is higher than 21, thus A is not highest
22+1+46=69 --->one is higher than 21, thus A is not highest
23+23+23=69 ---> all three are higher than 21, thus A is not higest.

I think the key to the answer is knowing
1) Disporportioned possibilities always leads to at least one higher than A
2) Evenly porportioned possibilities always leads to all three higher than A

I think one of the explanations someone gave explained the disporportioned possibility as a reason to choose B, but not taking into account the porportioned possibility could have still gotten the question wrong.

But since the porportioned result happens to correlate with what a disporportioned result is, we can still choose B as the answer.

This was a good question to think through. Thanks for question and dialogue guys. Amongst your conversation, I was able to conclude with what I just wrote. Very helpful. Thanks!
But this last option is the rea

my explanation is just simple like this:
the average of these 4 is 90/4 = 22.5, therefore 21 cant be the largest one. hence B answers the question straight away.
