On Friday I set this puzzle….
You have nine tennis balls and four shopping bags. Your challenge is to put the balls in the bags in such a way that there is an odd number of balls in each bag. That is, each bag must contain 1, 3, 5, 7 or 9 balls. Can you do it?
If you haven’t tried to solve it, have a go now. For everyone else the answer is after the break….
It is all about putting the bags inside one another. You could, for example, put 3 balls in each of 3 bags, and then place one of these bags in the fourth bag. There are lots of possibilities. Did you solve it? Any other solutions?
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.
