Henry Ernest Dudeney/Modern Puzzles/3 - Dollars and Cents

by : $3$

 * Dollars and Cents
 * An American correspondent tells me that a man went into a store and spent one-half of the money that was in his pocket.
 * When he came out he found that he had just as many cents as he had dollars when he went in
 * and half as many dollars as he had cents when he went in.
 * How much money did he have on him when he entered?

 * Pocket-money, which follows exactly the same pattern.
