Here is another mathematical puzzle for you.
This was recently asked in a Year 12 Further Maths exam in Victoria, Australia.
It was a multiple choice question, so I thought I would have a poll to see how well you can answer the question.
The question is:
A 50 cent coin has 12 sides of equal length. Two 50 cent coins are balanced next to each other on a table so they meet along one edge.
