Aman took a flock of ducks to market, and when he got back, his wife asked how he had done. He said:
"Well, first i sold Mr. Smith half of the flock and half a duck; then I sold Mr. Brown a third of what was left and a third of a duck; then I met Mr. Robinson and talked him into taking a fourth of what was left and three fourths of a duck; and on the way home i met old man Jones and sold him a fifth of a duck for good measure. Here are the rest of them, 19 ducks."
How many ducks did the man take to market to begin with? It may be pointed out that no duck was divided.
