Logic Question? [modified]
-
Tom has six pairs of black gloves and six pairs of brown gloves in his drawer. In complete darkness, how many gloves must he take from the drawer in order to be sure to get a pair that match? Just to have a little fun.... "C++ will solve any problem."

13 he could possibly take out 6 black left hand gloves and then 6 brown left hand gloves, the next one would have to be either the right hand or left hand match. "C++ will solve any problem." -- modified at 11:08 Friday 16th June, 2006

Wow, see I knew this one with socks - and then 3 would have been the answer. Didn't think at all about the "handedness" of the gloves... Cheers Martin

Remeber it says "how many TO BE SURE" "C++ will solve any problem." -- modified at 10:58 Friday 16th June, 2006
I heard this one with socks, not gloves. As Jun Du pointed out, some gloves can be worn on either hand. The lefthand/righthand issue was noted, but safely ignored because of this. :-D Good puzzle, though. I think that it would be better if the objects were shoes, instead of gloves, because then you could have no doubt that the left/right issue was inescapable. Josh

It depends on whether you can wear left glove on right hand and vice versa. This is old...some company's quiz test for new hires. Keep on trying. - It's easier to make than to correct a mistake.
I've been lurking here for a while but I had to respond to this one... A lot of people probably know this one (or something similar) but here goes: There are two rooms. In one there are four light switches, in the other there are four lights controlled by the swtiches. It is impossible to see into one room from the other. If you can enter each room only once, how do you determine which switch controls which light? Anyway, this being my first post.. Hello everyone, hope to be useful and/or entertaining.

I've heard it before, but with three.

An IBM or MS quiz? Don't remember which one. Three is easy, lets try four. I guess you need to label all four switches first. Then follow these steps: 1) Turn on switch 1, wait for a couple of seconds, then turn it off; 2) Waite a comple of minutes; 3) Turn on switch 2, wait for a couple of seconds, then turn it off; 4) Turn on switch 3 and leave it on; 5) Enter the bulb room to check: - The light on is linked to switch 3; - The warm one is switch 1; - The hotter one is 2; - The last is 4. Any other thoughts? - It's easier to make than to correct a mistake.

I came up with 8 because surely you can feel the difference between left hand and right hand gloves when you are picking them up. 1 left hand glove 7 right hand gloves

2. A logical person would turn on the light, use a flashlight, or would have installed emergency power-outage lights. Having reduced this to an already-solved problem, Tom simply retrieves gloves from the drawer as desired. :-> -- I've killed again, haven't I?

This solution requires the bulbs be incandesent. flourecent and led bulbs put out very little waste here, incandesent bulbs put out primarily heat with a little bit of light as an afterthought.
