Explain.

 

[Yurka]

say you take 1 from one bag 2 from another 3 from another and so on and each fake coin weighs a gram then each real coin weighs 1.1 grams
so say you use 5 different bags

1+2+3+4+5=15

so if its supposed to weigh 15 grams and it turns out weighing 15.3 then you know its the 3rd bag which is the real coins


wow that was hard to explain, it worked alot smoother in my head

please tell me im right, that took forever to think about

[Carcharodon]

That's gotta be the answer.

EDIT: Word.

 

[unstoppable]

[Majik1387]

^Boo, too much math skills needed for that one.

 

[Carcharodon]

Uh, yes.

 

[ampersand]

But how do you know the weights of the two different metals?

YURKA has something!

Spoiler

Lets say that theres 10 bags

the metal coins weigh 100 grams each

but the gold ones weigh 101 grams each, one gram more!

you name all the bags A, B, C etc...

take 1 from A 2 from B 3 from C etc...

add that up... it should be 5,500 grams

but it weighs MORE because the gold ones are in there, so how ever many

more grams it is than 5,500 is what bag it is...

so if its 3 grams more its bag C, 6 F, 7 G etc...

HA HA! i think i remember this riddle from Math earlier this year!

my teacher used a different version tho' and it was tuffer..

so i kind of already knew it so i'll put it in spoilers...

edit* damn i took too much time typing it out...

 

[Majik1387]

That's one reason why I couldn't figure it out

 

[Yurka]

yeah that threw me off, i just decided to put in my own numbers

 

[Carcharodon]

You can only do that if you know that one coin weighs 0.1g more than the others. If you got some number difference (decimal) that was divisible by, say, 2 OR 3 (like 0.12), for all you know, couldn't it be the second OR third bag? This really only works if you impose some theoretical number to it; in practice, you'd still be clueless.
