A coin collector knew that a lightweight coin was mixed with 8 more rare coins of equal weight. She found the lightweight coin in two weighings. how did she do it?

She was psychic.

Yea thats what I was thinking. Either that or she's afrodj13

The 8 coins were of equal weight of each other not equal weight of the lightweight coin.

lol. Actually, I should have put that down as my answer. Instead, I actually took the time to figure it out. I should have just sat there and stared at the hot senior. No wait, she sits all the way in the back of the class. Damn. That room is extremely cold too.

No school for me, no more ditzy blondes, no more potheads, no more liberal communist teachers, NO MORE SCHOOL!

who knows and who really cares.
i guess that this is why it is posted in the offtopic B.S. section. anyway as i said before i dont see why anyone would really care about it and i will leave it at that.

That is the whole point, for nobody to care.

The coin was painted brught red and the rest were silver.

OK,

here goes

you have a total of 9 coins, you break them up into 3 groups of 3. you take 2 groups and weigh them against each other.
You have 2 possible solutions, they are equal or one is lighter then the other

If they are are equal then you take the last group and weigh 1 coin against 1 coin. if they are equal , your last remaining coin is the lightest.
or you will have a one coin lighter then the other

If one is lighter, you take that group and weigh 1 coin against 1 coin. if they are equal , your last remaining coin is the lightest.
or you will have a one coin lighter then the other

That's EXACTLY right, rudedog! I would mail you a cookie, but it would probably go stale before it got to your house.

Rudedog is smart. hes as smart as a smart fox that went to the university of smartness and then became the head of the divison of smartness in the US govt.

The US government is smart? LOL... that's a new one. :lol:
