Bingo!
A group of us were playing Bingo. I noticed something very interesting. There were different Bingo cards with no two cards having the same set of numbers in corresponding column or row. The centre of course was free space.

A Coin Game
Recently, a friend of mine showed me a very interesting game with coins. She asked me to bring three saucers first and she placed them in a line. Then she placed 5 coins of different denominations, one on top of another in the first saucer.
The coins were of the denominations Re 1/-, 50P, 10P, 5P and 25P and she placed the coins in the order of their size—smallest on the top and biggest in the bottom.
She now asked me to transpose these coins to the third saucer observing the conditions that I transpose only one coin at a time, I do not place a bigger on a small one and I use the middle saucer only temporarily observing the first two conditions but that in the end the coins must be in third saucer and in the original order.
‘Oh that’s very simple. This hardly needs much effort’ I said.
I took the 25P coin and put it in the third saucer. Then I kept the 5P coin in the middle saucer. Now I got stuck. I did not know where to put the 10P coin. It was bigger then both!
My friend smiled and said ‘put the 25P coin on top of the 5P coin. Then you can put the 10P coin in the third saucer’.
