Simple Puzzle Which I Took from shakuntala Devi's Puzzle Book : 
It is a small town railway station and there are 25 stations on the line. At each of the 25 stations the passengers can get tickets for any of the other 24 stations.

Now Find Out how many different kinds of tickets that the clerk has to keep ?
