This week’s puzzle

A bit of light relief. See if you can solve this classic logic puzzle:

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?

Answer to last published puzzle:

The man picks up a piece of wood and lights it from the fire on the west end of the island.

He then quickly carries it near the east end of he island and starts a new fire. The wind will cause that fire to burn out the eastern end and he can then shelter in the burnt area.

The man survives the fire, but unfortunately dies of starvation, with all the food in the forest burnt.
