Answer....
Before entering the room turn 'ON' let’s say the first 2 of the 3 light switches, leaving the 3rd switch 'OFF' and wait for a minute or two.
Turn the 1st light switch 'OFF' leaving only the 2nd switch 'ON' and enter the room.
If the light is on…. Yes, switch 2 is the answer
If not… touch the light globe and if warm…. switch 1 is the answer
If not… yep you got it…. Switch 3 is the answer.
There are three light switches outside a closed room. Only one switch is connected to a light bulb inside the room.
Each of the three switches can be either 'ON' or 'OFF'.
You are allowed to set each switch the way you want and then enter the room but you can only enter the room once.
How do you determine which switch controls the light bulb ??
Just turn all 3 switches to the on position... Nothing in the puzzle conditions says you can't do this
