Two market women were selling their apples, one at three for a penny and the other at two for a penny. One day they were both called away when each had thirty apples unsold: these they handed to a friend to sell at five for 2¢. It will be seen that if they had sold their apples separately they would have fetched 25¢, but when they were sold together they fetched only 24¢.
"Now," people ask, "what in the world has become of that missing penny?" because, it is said, three for 1¢ is surely exactly the same as five for 2¢.
Can you explain the little mystery?
