Old one but still challenging... You must rescue a princess who is being held in 1 of the 2 rooms at the end of the hall. You do not know which room she is in, and each door to the rooms has a guard infront of it. If you choose te wrong door you will die. One of the guards can only tell the truth, while the other can only lie, you unfortunately do not know who tells the truth. You may only ask one question to either of the guards. What question would you ask to definitively know what room she is in ?
