Lightbulb Riddle?!
Question: Ok, there are three lightbulbs in a closed room. You are outside of the room and you can only open the door once. There are three switches outside of the room which you can only turn on any two of your choice.
How can you tell which switch belongs to each light bulb?
Recap:
3 lightbulbs in 1 room
Only open door once
Only turn on 2 of the 3 switches <<<<< you can use this as a minor hint

Turn on a switch and wait for 10 minutes. Then switch it off, turn on another switch and walk into the room. The switch that is on is the one controlling the bulb that is on. Then, feel the other two bulbs. The one that is hot is controlled by the one you turned on and off. Naturally, the last switch controls the cold bulb.
well if you switch two and the lights doesn't come on then its the other one
first switch on one bulb for few mins ans switch it off
next switch on the second bulb and go inside the room
now the bulb on belongs to the 2nd switch...then touch the other two bulbs..the warmer one will belong to the 1st switch and the cooler one belong to the untouched switch...
hope u r clear
