HI all,

At 12:37 on 1/02/2010 you wrote 
Fair enough, although I didn't see any other responses.  That's what you get for being at the beach on Friday!  So, Gary, what are the answers you had for questions two and three?


Answer 1

Weigh balls 1, 2, 3 against 4, 5, 6. If they balance, compare 7 and 8; if they differ, take the heavier set (say 1,2,3) and weigh 1 and 2. If they balance, ball 3 is heaviest.


Answer 2

If there are N pirates, give half of them just over 1/N of the loot each (which is more than they’d expect by even distribution). Keep the remaining loot (just under half the total).


Answer 3

Suppose there are only two married couples in the village. When the queen makes her announcement, Wife 1 knows Husband 2 was unfaithful. Now she knows that if Wife 2 sees that Husband 1 is faithful then Wife 2 will kill Husband 2 on the first day because at least one of the two men is unfaithful and it isn’t Husband 1. 
However, Wife 2 doesn’t kill her husband. The only reason being because she knows Husband 1 is unfaithful. Because both husbands are still alive on the second day the wives know both are unfaithful. So on the second day both husbands are killed by their wives. 
What happens with 100 married couples is that the wives have to wait till the 100th day before they can prove that their husband is cheating.

On the 100th day there is a bloodbath: all the men are killed by their wives.


..... till next time.
