One gets a bite, the other gets the rest.

Here is a good hint, and I do not think you should be given more.

It is this type of puzzle:

This is not yours, I just found a similar puzzle pic on line. But  I would tackle the problem with a grid like this one.

I have not done it, I am just assuming that this would be the right approach.

You put a cross in all the ones that do not work and a tick in the ones that do work until you have averything filled in.

You start by putting a tick in the red house box, which means that you can cross all the other colour houses. etc.

Your teacher probably already told you this much anyway.

Good luck.

Come on Jenny.

This is a challenge question that your teacher has given the class.

Maybe there is some prize, or at least prestige, for getting it nutted out.

Do you really think it is right for you to get other people to do it and present it as your own?

Why does this not surprise me.

Thanks Jenny  :)

I am not sure that it is right but this is my logic.

It is a circle and rotations are considered the same.

In order to deal with this I have fixed on number in place. 

I do not think it makes any difference which initial number you use so the chance of getting this first place right is 1.

Say that first place was filled with an A number. Then the position of the other two As is already fixed. there are 2!=2 ways the other A's can be placed.

There are three fixed places for the Bs  so that is 3! ways and the same for the C's.

so that is where I got  2!3!3! from

I cannot see a problem with your logic CU.

It would be good if some other knowledgable person also voiced their agreement though.

I am closing this as sinclairdragon is obviously not interested in discussing anything.  

He is only interested in the final answer.

I know this becasue he has reposted.  I have locked that one too.

I do not want this site to be known primarily as a cheat site.

Here is your original post you lazy git.
