Three light bulbs and switches
There is a room with a door (closed) and three light bulbs. Outside the room there are three switches, connected to the bulbs. You may manipulate the switches as you wish, but once you open the door you can't change them. Identify each switch with its bulb

A B C say r the three switches.
1.Turn A on
2.Keep B off
3.Turn C n for a while and turn it off just before u go in.
After u go in, u know the bulb A corresponds to coz it is on.
Touch both the other bulbs, the one that is hot corresponds to C and the other is B.
