Brain teaser #16
A beggar found a leather purse that someone had dropped in the marketplace. Opening it, he discovered that it contained 100 pieces of gold. Then he heard a merchant shout, "A reward! A reward to the one who finds my leather purse!"

Being an honest man, the beggar came forward and handed the purse to the merchant saying, "Here is your purse. May I have the reward now?"

"Reward?" scoffed the merchant, greedily counting his gold. "Why the purse I dropped had 200 pieces of gold in it. You've already stolen more than the reward! Go away or I'll tell the police."

"I'm an honest man," said the beggar defiantly. "Let us take this matter to the court."

In court, the judge patiently listened to both sides of the story of a leather bag lost and a leather bag found. He counted the coins; 100 gold coins in total. Then said, "If all was said is true then it's clear that no reward is necessary."

How did the judge rule on this case?

2. Pete's sale was neither the most nor least expensive and closed before Roy's.

3. Dale's sale on Main Street closed before Katie's sale on Oak Street.
