Five pirates find 100 gold coins in their recent loot. In order to distribute the loot among them, they use the following approach:
The most senior pirate will propose a distribution. If at least half of them agree with the proposed distribution, the loot will be divided as proposed. Otherwise the most senior pirate (who made the proposal) will be killed. Then they start over with the next most senior pirate, and so on.
The question is: what distribution should the most senior pirate propose so that he won’t be killed? Assume that the pirates are intelligent, greedy and prefer not to die.
Update: The solution is posted in the comments section.
