Henry Ernest Dudeney/Modern Puzzles/1 - Concerning a Cheque

by : $1$

 * Concerning a Cheque
 * A man went into a bank to cash a cheque.
 * In handing over the money the cashier, by mistake, gave him pounds for shillings and shillings for pounds.
 * He pocketed the money without examining it, and spent half a crown on his way home, when he found that he possessed exactly twice the amount of the cheque.
 * He had no money in his pocket before going to the bank, and it is an interesting puzzle to find out what was the exact amount of that cheque.
