Puzzles and Curious Problems by Henry Ernest Dudeney: $17$
- The Missing Penny
- Here is an ancient puzzle that has always perplexed some people.
- Two market women were selling their apples, one at three a penny and the other at two 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 twopence.
- Now it will be seen that if they had sold their apples separately they would have fetched $2 \shillings 1 \oldpence$,
- but when they were sold together they fetched only $2 \shillings$
- Can you explain this little mystery?
