In order to solve this puzzling riddle, you will have to think logically. Not everyone can figure it out. Can you?
In a house, there is a room with a light bulb inside. The door is closed, and you are outside the room. There are three switches outside the room. Only one of them operates the light bulb, while the other two do nothing. The room has no windows, and there is no way to see inside the room or tell if the light is on or off when the door is closed.
