Basement Attic Light Switch Riddle

You are in a basement with three light.

Basement attic light switch riddle.

The famous light bulb riddle. Go upstairs and touch the bulb. The door to the room is closed and there are no windows. Test your brain logic by trying to solve this real life situation riddle.

I was thinking about the light switches. As long as you don t stop for a beer before running up the light that s off but warm to the touch is the first switch. Then switch 1 would be the switch. There are three light bulbs in your attic.

You are in the basement of a house where there are are three identical on off switches. If you have 3 switches downstairs have a time delay of 5 minutes between each switch. You can play with the switches as much as you want and after that you can visit the attic above just once. There are three light switches outside a room.

One of them controls a lamp in the attic and two of them do nothing. If the bulb is cold. Inside is a single light bulb controlled by one of the three switches. However you know the light is off to start.

How can you find out which switch to which bulb corresponds. That is switch on 1 2 wait a minute switch off two and go to the attic and check if the bulb is on hot or cold. You need to determine which switch operates the bulb. The door is closed and you cannot see if the light is on or off through the door.

Switch 3 on 5 minutes then off. Switch 1 leave on 5 minutes then shut off. You must determine which needs saving and remove the other two. The light on is the second and the light off is the switch you didn t flip.

How can you figure out which light switch goes to which light bulb by only making 1 trip upstairs. There is no one there to help you. Outside of the closet there are three light switches. You can turn the switches on and off as many times as you wish they are all off to begin with but may only enter the room once.

You have no way to see into the attic or to see reflected light from the attic. Flip a second switch and run up to the attic. All of them are turned off and their switches are installed downstairs. It s basically the same solution as our first idea.

There are three switches in the basement two of which are useless one is connected to a lightbulb in the attic. Switch 2 on 5 minutes then shut off.
