At Duke University, there were four sophomores taking Chemistry and all of
them had an "A" so far. These four friends were so confident that the
weekend before finals, they decided to visit some friends and have a big
party. They had a great time, but after all the hearty partying, they
all day Sunday and didn't make it back to Duke until early Monday morning.
Rather than taking the final then, they decided that after the final they
would explain to their professor why they missed it.
They said that they visited friends but on the way back they had a flat
tire. As a result, they missed the final. The professor agreed they could
make up the final the next day. The guys were excited and relieved.
They studied that night for the exam.
The Professor placed them in separate rooms and gave them a test
booklet. They quickly answered the first problem worth 5 points. Cool,
thought! Each one in separate rooms, thinking this was going to be easy.
Then they turned the page...........
On the second page was written.....
For 95 points:
Which tire was it, that went flat?
