Bertie:Melody says that things have gone quiet so I am taking the opportunity to share a problem.
I first encountered it as a twelve year old and have just rediscovered it in an old notebook.
I remember that it took me (seemingly) an age to come up with a solution that didn't just
involve trial and error, and I'm wondering now if there are any other methods of solution
different to the one I found.
A man receives a cheque and goes to his local bank to cash it.
The cashier at the bank is having an exceedingly bad day and mistakenly mixes up the
dollars and cents, (pounds and pence in England), giving the man y dollars and x cents
rather than x dollars and y cents. The man doesn't notice the mistake and returns home,
on the way spending 5 cents of the money. (He had no other money with him when he left home.)
Only when he gets home does he check, and he finds that he now has exactly double
the amount on the cheque.
The question is how much was the cheque for ?
