Women Or Tigers? — Solution to Fourth Challenge

So how was yesterday’s logical exercise? Still too easy? Let’s crank it up a notch then. That’s what our friend the king did. But that’s for tomorrow. Let’s first look at the (best) answer to yesterday’s challenge.

If the sign on the door to Room I tells the truth, there would be a woman in both rooms. That, however, is impossible, as Room II would have to contain a tiger to tell the truth.

Therefore, the sign on Room I must be lying. There is thus a tiger behind it. And it does matter which door you choose — ergo there must be a woman in the other room, Room II. Also, it then fits that the sign on this door is lying too.
