Henry Ernest Dudeney/Puzzles and Curious Problems/12 - Reductions in Price

by : $12$

 * Reductions in Price
 * "I have often been nystified," said Colonel Crackham, "at the startling reductions some people make in their prices,
 * and wondered on what principles they went to work.
 * For example, a man offered me a motor-car two years ago for $\pounds 512$;
 * a year later his price was $\pounds 320$;
 * a little while after he asked a level $\pounds 200$;
 * and last week he was willing to sell for $\pounds 125$.
 * The next time he reduces I shall buy.
 * At what price shall I purchase if he makes a consistent reduction?
