 There is a room that is like this. The vertical line in the middle is the wall. Each switch works for one light bulb, and no switches work on the same light bulb. All the switches are off at first, and you are at where the stick figure is. And here is the question! You have to figure out which switch works on which light bulb. But, you can only go into the bulb room only ONCE. The only way you can check the light bulbs are to go into the room. (So it's not transparent, you can't break the wall) Now, how would you solve this? Summary: (+) You are at where the stick figure is (+) Each switch work only on one light bulb, no 2 work on the same one (+) The only way to check the light bulbs is to go to the bulb room (+) The room is accesible only once |

| This is so easy considering those bulbs are incandescent (sp?). 1. Turn one switch one for several minutes then turn it off. 2. Turn another on. 3. Go into thew room. 4. Check which bulb is off feels warm. That one is for the first switch you flipped. 5. The light that is turned on is the 2nd switch you flipped. 6. The one that is off and cool is the switch you didn't flip. (edited by RT-55J on 06-11-05 03:37 AM) |
