Turn two switches ON, and left one switch OFF. Wait 10 minutes. Then shut one of the ON switches OFF. One switch is ON and two are now OFF. Immediately go into the room. If the light is on, you know it's the switch that is still ON. If the light is off, feel the light bulb. If the bulb is cold, it's the light switch that you never turned ON. If the bulb is still warm but the light is off, it's the switch you turned ON but then turned OFF prior to entering the room.
See it's more than visual. You have to use your sense of touch....not intuitive with a light bulb riddle!
i know the correct switch will be the one that turns the light on...
the light switch would the side closest or furthest from the door
turn 2 on go inside the room if the light is not on its the other switch, if it is on you have a 50 50 shot
agree with tiju... haf a star!!
just switch them all on then open the door and turn one off at a time. which ever turns off the light is the right one :).
...tij wins, I loose :(
thats easy flick the top switch and go in the room, if the light is on great, if not flick it off and try the middle switch. enter the room a second time, if the light is on great, if not then you know it will be the bottom switch. (i'm not sure if you have to be in the room knowing the correct switch or outside the room, it doesnt say, but if you have to remain in the room then i would flick all three at once)
u know smthing 1 can actually switch on all the 3switches& obviously light will switch on!!! i mean u only want to get that light on right!!!!!!!!!
there are 3 switches therfore there must be 3 lights,of which one light is inside the room and the two othersare outside the room turn onfirst switch if one of the lights outside the room is glowing, turn on the next switch.If the second light outside the room is glowing then the third switch is the switch for the light inside the room,if not the second switch is for the light inside the room
