Puzzle from Proof: Seven Gold Rings
In our latest podcast about the movie "Proof", we set the following puzzle:
Tom employs a labourer, who is going to work for him for seven days.
Every day he wants to pay the labourer one gold ring for each day they have worked.
Unfortunately Tom is a strange person who keeps his gold in the form of a chain with seven gold links, and a miser who doesn't like wasting gold. What is the minimum number of links that Tom must cut in order to make sure the labourer can always leave with the correct number of gold links?
Post your comments or answers below, and we'll give you the answer at the end of our next podcast.
