there is a room with a light bulb.
outside 3 switches
you can flick 2 switches and enter the room once, how you find out which switch turns on the light.
Just takes a little bit of logic!

Leave the first light on long enough to get i warm, turn it off, then switch on the second light and leave it on until you go into the room. The first light is the warm one the second light is on and the third light is off and cold.
Don't blame me....it's the answer.
Switch one switch then enter room.
Is light on - if yes that is the switch.
If light not on - leave room with door still open - switch second switch on.
Is light on - if yes that is the switch.
If light not on then the remaining switch is the one that turns it on.
Unless of course the light bulb is dud.
Press the one on which 'L' is printed... LOL... ('L' for lamp).
OK lets be serious... Press any two switches, if one of them is for the bulb, then it'll glow. If the bulb doesn't glow then the third one is the right button.
I am yet to figure out the connection between switches and entering the room.
Stop Scrolling Down And Look At The Ansers Above.
FLICK the two switches then just PULL the other one down
turn on one light, leave it on so it gets hot. then turn it off. then turn on one light and go and see which light is which. the bulb that is hot is the one u turned on 1st, the one on but still cool is the one u just turned on and the other one is not on at all
u dont have to enter to see so just leave the door open when u switch them on.
