A Queen's decree
Hope y'all like this one:
If there were one unfaithful husband, his wife would realize immediately, seeing as she knew of none and there had to be one, and would kill him the first night.
I have seen similar problems before, and I must say the reasoning expected makes me kind of uneasy. Look at it this way. A woman knows 39 other adulterous men. She does not know that her husband is adulterous. But we expect her to think 'Day one gone. So the answer is not 1. Day 2 gone. So the answer is not 2....' till 'day 39 gone. Hey it must be my husband!'. I understand the logic. I just cannot see myself thinking like that if I were that woman.
While I agree with your point, Ravikiran, I feel that a women who instinctively knows about all other unfaithful husbands on the island, and who is prepared to shoot her husband after just thinking about the problem is obviously capable of anything.
I've seen this problem told in a lot of different ways. The coolest description of this problem I've seen is in the book "Labyrinths of Reason" by William Poundstone. In that one, the "women" are extremely paranoid employees of a merging mega-corporation, who live in constant fear of losing their jobs.
