Who is the most logical and intellectual on TSR???

How does this determine who is the most intellectual?

I'd just go out out and buy some digital scales...

His solution doesn't work. In fact I'm reasonably confident that it impossible to solve the problem with six coins and two weighings, so you need to do more on the first step (either get down to a smaller group or get some information about whether it's heasvier or lighter).
As 13 isn't divisible by 3, the approach seems unlikely to work with that many coins.

Sorry if im just being plain stupid, but in 3) im presuming you select 2 from the 3(with fake in) to compare with 2 from the 9 you have established are not fake. I accept that IF the 2 you select from the set of 3, weigh the same as the 2 you select from the 9 gold ones then the unweighed one is fake. But I don't understand how you would find the fake one if the 2 you select from the 3 would weigh differently to the 2 real ones :s again sorry if im being silly

Ha! I did it in just under an hour. Am I a genius?

Just to be a dick I'm going to neg rep this post.
BTW I'm not the same person who neg repped your other post.

This doesn't really prove who is most intellectual or logical, but assuming he isn't lying and that he really did do it in 4 minutes from first principles, then it does prove that HistoryRepeating is very good at discrete maths. Though quite likely he is big headed enough already.

Also, I really wish I had kept trying to see how long it took me to do, rather than just giving up after 2 minutes :-/

Is it actually correct though? Because it seems the last bit requires a bit of luck (chance) to get it done within 3 weightings.

In step (2) he discovered whether the fake is lighter or heavier, so if in step (3) the two coins weigh different amounts, you will know whether it is the heavier or the lighter one you need to choose. If in step (3) they weigh the same, then it is the unweighed one which is the fake.

i think someone's mad. your iq low bro? you think you were a 170 and you got handed a 112? sucks man. but don't worry, youll look cool at the pub quiz when you get an answer or two more than the builders.

This is wrong because Step 2 will not tell you if the fake is heavier or lighter if you weigh 3 non fakes against 3 non fakes.

low IQ haha, I couldnt care less what my IQ is, but I have an offer to study and arguably the third best university in the UK, now I dont know about you, but I'd rather study at a top university then have an IQ of 200 and work at tesco's. If I gave the slightest care about what you think, then I'd take the mensa, but its a waste of time. Enjoy boasting about your IQ score from an online test when i'm at my top paid job coming from a top university

I don't see how 13 not being divisible by 3 causes a problem for his system (actually I'm pretty sure my system can also deal with 13 coins including one fake (you can work out for 5 coins in 2 weighings)), it just alters the specific weighings which you do.

hey, its not my fault youll never come up with anything inventive man, dont shoot the messenger. youre just not a da vinci or a newton. its okay. you can still be worth something, somewhere. your family will always respect you, even if they hold others in awe.

if you didnt care what i or others thought, you wouldnt have just told me that story about your university prospects and top paid job plans.

You sound like my little brother, and he is stupid



You seem to think IQ is the most important thing in the world, just letting you know the world isnt like that. Absolutely noone cares about it. I usually care about what people think, unless they are IQ lickers.

nice talking to you
