Something for the Weekend, Sir?
To quickly warm up the grey cells, a lonely box of chocolates sits on the table for all to share. When Chris saw it, he ate 1/6 of the box. Then along came Wizard of Oz and he ate 1/5 of what Chris left. Along came Slavy who ate 1/4 of the chocolates that remained. Later that day, DP ate 1/3 of the remaining chocolates. By the time I got there, I managed to eat 1/2 of what remained. When my friend, Kaliprasad came along, only 4 chocolates remained in the box.
Just how many chocolates did Chris manage to eat?
You are in a roomful of 35 people. Everyone is asked to shake hands with everyone. How many handshakes will there be? The answer would be nice, but a formula for calculating any number of handshakes for a given number of people will gain you extra bonus points.
You are ToM Annual Conference in Vegas with 40 people of varying heights. Chris the Question Master has set a series of puzzles, and after 1 hr of hard puzzling, has asked you to exchange papers for the purpose of marking them. However, nobody is allowed to change papers with anyone that is shorter than themself.
How many exchanges will occur?
