I know ya'll love brain teasers, and it gives me something to blog when I don't have any other ideas. So here you go.
. 1. A man rode into town on Friday. He stayed 3 days and left on Friday. How is this possible? (I got this one from the tv show iCarly).
The man's horse is named Friday.
2. Four men sat down to play,
They played all night ‘till break of day.
They played for gold and not for fun
With separate scores for everyone.
When they came to square accounts,
They all had made quite fair amounts.
Can you the paradox explain,
If no one lost, how could all gain?
Answer: The 4 men are musicians.
3. There is a well known story of a famous German mathematician, who showed his brilliance even as a young boy.
While in elementary school, he was given the problem of finding the sum of all the whole numbers from one to 100.
For most of use it would be a long and difficult task of adding "1=2=3=4 etc." This young lad, however, solved the problem in his head in just a few moments.
What is the answer and how did he manage to do it in his head?
Answer: Imagine a measuring tape that measures 100 inches. Fold it in half at the 50" mark. The 1" is matched with the 99", which if you add together equals 100. 2+98=100, 3+97=100 and so on. By adding the matched numbers 1-49 with their counterparts, 99-51 you get 100 49 times, 4900. Add the 100 at the end and the single 50 in the middle. The answer is 5050.
Thanks for playing!
