It has been quite a week. For anyone that missed the fuss, we announced the launch of Dream:ON, our new iphone experiment into dream manipulation. It was been covered by media across the world and we hope that you can take part.
So, to the puzzle….
Yesterday I bought a strip of multi-coloured cloth. One third and one quarter of it is black, and the other 8 metres are red. How long is the strip?
As ever, please do NOT post your answers, but do say if you think you have solved the puzzle and how long it took. Solution on Monday.
I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for theKindle (UK here and USA here) and on the iBookstore (UK here in the USA here). You can try 101 of the puzzles for free here.
