I'll just answer it. You can post the next one.
he doesn't actually need to ask both of them
he asks: "If I would ask your brother, what would he say which door lead to safety"
Both answers will be the same and safe path is another one
One that tells truth will think "right door is A /for example/ - my brother lies so he would say "B", but I am saying truth, so my answer is that my brother would say - "B"" and he tells "B"
One that lies thinks: "right door is A, my brother tells truth so he would say "A", but since I am lying my answer is that he would say "B"" and he also tells "B"
They will both provide same answer and door that leads to safety is other one.
