Default Logic puzzles

Easy one first,

Two guards guarding two doors, one is the door to freedom the other is to Hell.
One guard always lies the other always tells the truth, however you don't know which guard is which. The doors both look the same.

You can ask one question and know which door is which, what is the question?


Regards
M. Gregg

Ask a guard what ithe other guard will say is behind the questioned guard's door.

Hell boy will say that heaven boy will say the hell boy is guarding heaven (ie heaven boy's door "hell"). Heaven boy will say that hell boy will say that heaven boy is guarding hell So if you want freedom go to "hell"

Yes correct!

Next,

A man needs to cross a river, he has a boat.

He needs to get a LION, PIG, and potato across the river.

When he is with them they are OK, however if the lion is left with the pig it will eat it, If the pig is left with the potato then it will eat it.

How does the man get all three across the river?

Regards
M. Gregg

You don't bury the survivors. No, wait... a peacock doesn't lay eggs. No, wait... the bear is white. No, wait...

Man puts the potato in his pocket, takes the pig, then goes back and gets the Lion.

Chuck the potato across the river, the pig will see it and being clever, swim over to eat it. However, pigs are slow swimmers, so you can row the lion across by boat and pick up the potato before the pig gets there.
