This is a Maths problem I got from a book from a very famous author of mathematical problems called Adrian Paenza. I hope you like it. I will start posting only one problem and if you want more, comment so I can add more problems.

I recommend you to read it very carefully so you get the right answer. It is not so difficult if you think it twice.For the ones who don`t like maths problems, I tell you that this is more a challenge because it is very fun. Remember read it carefully!!! Post the answer in the comments if you want, or tell me the answer at school.

Here it goes:

You have 10 bags each has one number:1 ,2 ,3 ,4 etc. Each bag has 10 coins each. Every coin weights 10 grams , except for one bag that has 10 coins that weigh 11 grams, (one more gram than the rest.)You also have, a one-pan scales,

**BUT**you can use it only

*time.*

**one**The problem consists in finding out, which is the bag that has the coins of 11 grams using the scales only one time.

You can`t find out without using the scales , you can`t grab one bag with your hand and decide that this one or that one weighs more! (That is not valid and it is difficult to use your senses)

Try to sort it out!! Quite difficult no?

I hope you can understand it and you like it. I will post the answers tomorrow.
