A man is leaving on a business trip and stops by his office on the way to the airport. The night watchman stops him and says, "Sir, don't take that flight. I had a dream last night that your plane would crash and everyone would die!" The business man cancels his trip and sure enough, the plane crashes, killing all the passengers. The man gives his watchman a $10,000 reward for saving his life, then fires him. Why?
That's why!

What exactly happened?
The man awarded $10000 obviously for saving his life. The duty of night watchman is to keep watch on office at night not to sleep & dream.
That's why he fires the watchman.
A snail creeps 10 feet up a wall during the daytime, then falls asleep. It wakes up the next morning and discovers it slipped down 6 feet. If this happens each day, how many days will it take to reach the top of a 20 feet wall?

Read the question first!
Let's find out progress of snail day by day.
Day 1 : UP to 10, DOWN to 4
Day 2 : UP to 14, DOWN to 8
Day 3 : UP to 18, DOWN to 12
Day 4 : UP to 22 which is greater than 20.
So snail requires 4 days to reach the top of the wall.
