You Are In A Room With Three Light Switches

One of them controls the light inside the room.

You are in a room with three light switches.

Turn switch 3 on. Each light is connected to one of three switches outside of the room. There is a room with a door closed and three light bulbs. Only one does anything and it turns on the light downstairs.

From here you can t see the light and it makes no sound. You can go into the room one time only to see the light. You are standing in a hallway next to 3 light switches that have been switched off. Turn on switch x for 5 to 10 minutes.

Turn switch 2 on for five minutes and then turn it off. Call the switches 1 2 and 3. You are only allowed to go into the room once. You re in a room with three light switches each of which controls one of three light bulbs in the next room.

You are allowed one and only one trip to the other room at which time you have to determine which switch controls which bulb. You have a set of 3 light switches outside a closed door. You can inspect the other room only once. Each switch operates a different light bulb in the room.

Feel the light bulbs for heat. Outside of the closet there are three light switches. There is another room down the hallway with 3 light bulbs all are incandescent light bulbs and each light bulb is operated by one of the switches in the hallway. Determine which switch operates which bulb.

The bulb that is off and cold is controlled by switch 1. Identify each switch with its bulb. Punishment for failure to solve this is having to listen to obama speak for an hour. Do it the electrical engineering way and put a video camera in the room and wait 15 minutes before flipping each switch.

However you know the light is off to start. Leave switch 1 off. If a bulb is on it s controlled by switch 3. Outside the room there are three switches connected to the bulbs.

In front of you are three light switches. This is a simple problem. You cannot see the whether the light is on or off from. You are outside the room and the door is closed.

The door to the room is closed and you cannot see the light bulbs from the hallway. You need to determine which switch controls which bulb. The warm bulb is controlled by switch 2. The door is closed and you cannot see if the light is on or off through the door.

It s really a stupid question though that says nothing. With the door closed from outside the room you can turn the light switches on or off as many times as you would like. You are standing outside a room next to three switches all of which are off. The three switches control three light bulbs in another room.

How can you find out which switches are connected to which. Before opening the door you may play around with the light switches as many times as you like. But once you ve opened the door you may no longer touch a switch. Let the bulbs be x y and z.

Each bulb is switched off at present.
