Puzzle for Today
Puzzle No. 322 – Thursday 26 September
A row of around ten coins of various denominations are placed on a table. Justin and Steve take turns to take a coin from either end. They continue to do this until there are no coins left. Justin and Steve then add up the value of money they have collected. The winner is the person who has collected the most money. It is possible that you can always create a winning game by understanding a very simple mathematical concept. What maths do you need to know?
