Sunday Times Teaser 2641 – Exchange Rate
by Robin Nayler
In preparing for a holiday I exchanged a three digit number of Pounds for Tezarland dollars, receiving a whole number of dollars for each Pound and paying an additional 12 Pound fee.
The number of dollars I received had the same digits as the Pounds I paid but in reverse order.
How many dollars did I receive?
