bonanova Posted June 7, 2008 Report Share Posted June 7, 2008 You're a magician, and you've just learned the neatest trick. The trick begins with a number of bags, each containing a different number of marbles. You have no bags or marbles, so you visit the local magic store. There you buy 15 black velvet bags. How many marbles do you need to buy if you use all 15 bags in your trick? Remember, this is a magic trick Quote Link to comment Share on other sites More sharing options...

0 Guest Posted June 7, 2008 Report Share Posted June 7, 2008 (edited) You would only need 15, just put one in each bag and then each bag in another bag. Thet way one bag contains 15 marbles and 14 bags, the next 14 marbles and 13 bags, and so on. Edit: Dang, I forgot about 0 marbles in one bag, should be: 14 Edited June 7, 2008 by Frost Quote Link to comment Share on other sites More sharing options...
