Study it more in depth, the answer is not 12, if you actually disect it and use mathmatics.

If it's not 12 it's not math but a language riddle.

Though craven you need to study the language to use the proper math, to get the answer so would it not fall under both.

I don't see how it could be anything but 12. Unless the words are intended to trick. I won't look for it but when the answer is found I'll see. I could easily be wrong but in a riddle this simple don't see how. Wouldn't have been the first time I didn't see it though.

Hey Mellow,

how long is that one hair? And how those 12???
Craven is right, I can't see any other answer to this one but 12.

Alexandra

ps. if this is a tricky riddle, than the answer could be also cent and a 1/2....but that isn't the answer, right?

I don't think there is another answer. I think you are bluffing. If there is an answer other than 12 please send it to me by PM. But no, I'm not going to research what I have now come to believe is a prank.

I believe that I probably put the riddle down wrong, I do not rember it very well maybe it was how much do 13 hairs cost. It was told to me by a close friend That went to MIT and Harvard, and when he told me the riddle he told me the answer was 8 or 9 cnt's. I put it here not as a prank, my stupidity itself is to blame.

Grrr! Still means there was not going to be a answer you were going to accept and that you were perfectly satisfied with letting us keep trying.

If you want to pull the "riddle-with-no-answer" trick don't choose math. ;-)

actually I was hoping that you knew of the riddle, I did not realize I had prob, messed up until today and actually tried to call the friend to get the accurate one. my mind has been a li'l out there recently getting used to this medication. when I get the acurate riddle I will repost it, which I know you will solve.

You are right the answer is 12 cents.

I have seen the kind of riddles before
and there was always a third part, which
is missing here.

If one and a half a hair grows one and a half mm in
one and a half days. How many mm does one hair
grow in 12 days?

yo mellow...your on the right track...
if 1 and 1/2 hair = 1 and 1/2 cents

then,

(12 hairs) times (1.5 cents) = 8 cents

take that back.
12 is actaully the correct answer.

because 1 = 1 / 1.5 = 1.5

so 1 x 12 = 12

Is the riddle supposed to read...
how many hairs are there if you spend 12 cents if 1 and 1/2 hair strand costs 1 and 1/2 cents?

12 x 1.5 = 8 hairs

Three points:

1. If 1 1/2 hair costs 1 1/2 cent then 1 hair costs 1 cent. 12 hairs would cost 12 cents.
2. 1/1.5 = 2/3 = .666666... and is not equal to 1 (nor is it equal to 1.5)
3. 12 x 1.5 = 18
