Weekly Problem 40 - 2008

Stage: 3 Challenge Level: Challenge Level:1

A 10p piece has a diameter of roughly 25mm = 0.025m, so there were approximately 25 $\div$ 0.025 = 1000 coins on the line. This means that the class raised about 1000 $\times$ 10 = 10000p = 100 pounds.

This problem is taken from the UKMT Mathematical Challenges.
