On Friday I posted this puzzle.
A shop sells chocolates for £1 each, and you can exchange 3 wrappers for 1 chocolate. If you start off with £15, how many chocolates can you buy?
If you have not tried to solve it, have a go now. For everyone else the answer is after the break.
You can buy 22 chocolates! Did you solve it? Any other answers? I have a funny feeling this is going to cause some debate.
I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for the Kindle (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.
