On The Line
November 29th, 2006 . by Vanaja
Today I have a very simple puzzle for you.
It is a small town railway station and there are 20 stations on that line. At each part of the 2 stations the passengers can get tickets for any of the other 19 stations.
How many different kinds of tickets do you think the booking clerk has to keep?
Solution
The answer is simple. 19×20=380
