3 rooms 3 bulbs

junk

there are 3 rooms upstairs each room has one light bulb but the switches for the bulbs are situated downstairs and you dont know which switch corresponds to which bulb. the switches are turned off initially ... you can turn on/off the switches any number of times you want, you can go upstairs only ONCE and need to figure out which bulb(room) corresponds to which switch. You cant get anyones assistance for this and you need to figure out yourself. do u know how.

The problem is I dont know the answer to this question

Assuming incandescent bulbs, this is a really EASY one. Just think about it.

flick on two of the switches, wait 5 minutes, turn off one of the two switches you originally turned on, go up stairs, check to see which one is still on, obviously corresponding to the switch you flicked on but did not flick off again. Then go to both lights that are off and see which one is hot to the touch.

Yep, that's how I figured it too.

And it is also probably assumed that time really isn't a factor. Which, if that's true, you could almost do it with flourescents as well.
