Have you managed to work out the Halloween themed Brainteaser yet? It was placed on our Facebook page this morning.

If you've come here looking for the answer, then look no further...

This weeks brainteaser asked you to solve the following:

Halloween was almost over and Mr Green had fewer than 20 sweets left.

When the doorbell rang, he thought he would give all the sweets away.

When he opened the door, there were two trick or treaters.

He wanted to give away the sweets evenly, but he noticed that when he divided the sweets in two, there was one left over.

At that point, he saw another trick or treater behind the first two.

Again, he tried to divide the sweets evenly among the three of them, but again one was left over.

Finally, another trick or treater came to his door, making it four trick or treaters altogether.

Mr Green still had one sweet left over after dividing the left over sweets into fours.

So how many sweets did Mr Green have left when the doorbell rang?

Any ideas?

Mr Green had only 13 sweets left when the doorbell rang. Thirteen is one

more than 12, which is divisible by two, three and four.
