In this family of puzzles, pirates vote not for justice, but for survival and self-interest. The approval rule has a peculiarity that changes the entire reasoning.
The five pirates: favorable tie
Riddle statement
Five pirates, ordered from oldest to youngest, must divide 100 coins.
The oldest proposes a distribution and everyone votes, including him. If the distribution receives at least half of the votes, it is approved; If not, the proposer dies and the next most senior pirate makes a new proposal.
Everyone is perfectly rational. Their priority is, in this order: survive, get as many coins as they can and, if everything else doesn't matter, throw another pirate into the sea.
What distribution should the most veteran pirate propose?
