WINNING SLIP
A contest is fixed. Everyone knows it, including the
contestants. One of the contestants, however, makes it to the
final playoff level.
The master of ceremonies presents the following challenge:
"This box contains two slips of paper. One slip has the word
'winner' printed on it, the other has the word 'loser.' Your
task is to select the winning slip - without looking, of course."
The contestant knows that this challenge is fixed. He realizes
that both slips have the word 'loser.' How can he select one
slip and win the challenge? By the way, the contestant can't
declare this contest is a fraud or he'd lose his current winnings.

ANCIENT MAN
An ancient Greek was said
to have lived one-fourth of his life as a boy, one-fifth as a youth,
one-third as a man, and spent the last 13 years as an elderly gent.
How old was he when he died? |
PALINDROME
A palindrome is a word or number that reads the same backwards as it
does forward. Numbers such as 606 and 4334 are palindromes.
While driving his car, Bob (so much of a palindrome lover that he
changed his name from John to Bob) observes that the odometer
reading forms a palindrome. It displays the mileage 13931.
Bob keeps driving. Two hours later, he looks at the odometer
again and, to his surprise, it displays a different palindrome!
What is the most likely speed that Bob is traveling?

FROG JUMP
A frog falls into a well
that is 18 feet deep. Every day the frog jumps up a total
distance of 6 feet. At night, as the frog grips the slimy well
walls, it slips back down by 2 feet. At this rate, how many
days will it take the frog to jump to the rim of the well? |
