Two women were selling marbles in a market place -- one at three for a dollar and the other at two for a dollar. One day both of them returned home when each had thirty marbles unsold. They put together the two lots of marbles and handing them over to a friend asking her to sell them at five for 2 dollars. According to their calculation, three for one dollar and two for one dollar makes it five for two dollars.

Now, they were expecting to get 25 dollars for the marbles, as they would have got if sold separately. But much to their surprise they got only 24 dollars for the entire lot.

Where did the one dollar go? Can you explain they mystery?

The friend sold sixty marbles at 40 cents apiece [5 marbles = \$2] and got \$24.
But the women expected \$25.
The mystery is not where is a missing dollar; it's why did they expect \$25?
