Basement Attic Light Switch Riddle

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.

Basement attic light switch riddle.

I was thinking about the light switches. It s basically the same solution as our first idea. Go upstairs and touch the bulb. There are three light switches outside a room.

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. How can you figure out which light switch goes to which light bulb by only making 1 trip upstairs. Test your brain logic by trying to solve this real life situation riddle. Turn on one switch for five minutes then turn it off.

The famous light bulb riddle. 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. All of them are turned off and their switches are installed downstairs.

If you have 3 switches downstairs have a time delay of 5 minutes between each 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 the bulb is cold.

Switch 2 on 5 minutes then shut off. The door is closed and you cannot see if the light is on or off through the door. There are 3 switches downstairs each corresponding to one of the light bulbs upstairs. You must determine which needs saving and remove the other two.

However you know the light is off to start. Flip a second switch and run up to the attic. You need to determine which switch operates the bulb. You have no way to see into the attic or to see reflected light from the attic.

The light on is the second and the light off is the switch you didn t flip. Outside of the closet there are three light switches. The door to the room is closed and there are no windows. Switch 3 on 5 minutes then off.

One of them controls a lamp in the attic and two of them do nothing. Switch 1 leave on 5 minutes then shut off. If you go upstairs to the attic you are not allowed to return to basement. There are three switches in the basement two of which are useless one is connected to a lightbulb in the attic.

How can you find out which switch to which bulb corresponds. There is no one there to help you.
