You look at the change in your piggy bank. It totals £58.29 and is made up of an equal number of five coins. You have 67 coins of each value. Can you tell us what the coins are?

I once cashed a cheque at the bank. I had spent £5.67 before I realised the bank clerk had made a mistake. He had transposed the pounds with the pence. I now had exactly 4 times the value of the original cheque. What was the original cheque's value?
