heres my shot at riddles. hope it is not too easy fer u guys..

theres a 2-storey house, single room on the top level
there are 3 lightbulbs in the room. all 3 light bulbs work well.

in the living room on the ground floor, there are 3 switches.
the 3 switches are for the lights in the room on 2nd floor..

how do you know which switch is for which (light bulb) ?


conditions;
-you cant leave the house,
-you can only go up the stairs once.
- you cant see the light from the ground floor
- you cant call yr friend, ask a friend to help, etc...

hope i explain the riddle clearly.....

maybe with a post like this, serious answers should be PM'd, jokey answers, and serious ones that are wrong should get posted.

So that people who come late or don't try to google the answer or haven't heard it before (or whatever) can still play along?

I'm working on it lol, but dang this is a tricky one! Did you make it up or did you find it somewhere?

let me see the possible combinations are:

1A
2B
3C

1A
2C
3B

1B
2A
3C

1B
2C
3A

1C
2A
3B

1C
2B
3A


.....

if we flick on switch (assume switch 1 lights light A), we get:

1A
2B
3C

1A
2C
3B

.....

if we flick two switches (1 and 2) and assume a and B light:

1A
2B
3C

1B
2A
3C


....
obviously flicking all three we are back where we started.

erg.... you googled for it :shock: .... I sat thought about it for 10min and got a similar answer PM'd him :P... thats funny

"ok.. Ive been thinking for about 10min and I think I got it... ok first turn the first switch on for about 5min and let the bulb heat up for a while then turn it off, and quickly turn the second switch on, then quickly run to the top floor... the hottest bulb will be the first switch, the bulb that is on, yet not quite as hot as the other bulb will be the second bulb, and the bulb that isnt on will be the last switch.... it may not be the correct answer... but i think it will work"

Is this an alternate way that doesnt not involve checking for heat? Or is it another variation on the on/light/heat theme?
