5 pirates of different ages have a treasure of 100 gold coins.
On their ship, they decide to split the coins using this scheme:
The oldest pirate proposes how to share the coins, and ALL pirates (including the oldest) vote for or against it.
If 50% or more of the pirates vote for it, then the coins will be shared that way. Otherwise, the pirate proposing the scheme will be thrown overboard, and the process is repeated with the pirates that remain.
As pirates tend to be a bloodthirsty bunch, if a pirate would get the same number of coins if he voted for or against a proposal, he will vote against so that the pirate who proposed the plan will be thrown overboard.
Assuming that all 5 pirates are intelligent, rational, greedy, and do not wish to die, (and are rather good at math for pirates) what will happen?
My guess would be there would be :
Round 1. Whatever the oldest pirate suggest, the other 4 will vote against. 4 - 1 Oldest pirate dies!
Round 2. Whatever Pirate2 suggest, the other 3 will vote against. 3 - 1 Pirate2 dies!
Round 3. Pirate3 should suggest Pirate4 gets 33coins, Pirate5 gets 34coins and himself gets 33coins. Pirate5 says AYE! Pirate4 says NO! Pirate3 says AYE! Since he won't wanna die.
