Women Or Tigers? — Solution to Second Challenge

Got yesterday’s challenge? Got it solved?
Well, it wasn’t very difficult, was it?

Here’s the solution:

Since either both signs tell the truth or both tell a lie, it means that if the sign on Room I is true, the one on Room II is true as well. Therefore, there must be a tiger in Room I and a woman in Room II.

It is not possible that both signs tell a lie. That would imply, according to sign #1, that there is no woman, only tigers — and as sign #2 says there is a tiger, this one cannot be lying as well.

Hence, both signs tell the truth, and the prisoner will find his bride behind the door to Room II.

Tomorrow we’ll be back with a bit more of a challenge. Do check it out, it’s fun!
