A farmer has one rock weighing 40 pounds. Using a balance scale and this rock, he can measure 40 pound units of wheat, which he sells at the market. One day, his neighbor comes by and borrows the rock. After a few days, the neighbor returns and tells the farmer that he has some bad news and some good news.
The bad news is that he dropped the 40 pound rock and it broke into four pieces. The good news, he says, is that the farmer can now use these four fragments to measure any amount from 1 to 40 pounds, to an accuracy of one pound. How much does each rock fragment weigh?

I don't get it ???
If one fragment weighs 1 pound then you don't need any of the other 3 pieces.
1-To weigh 1 pound, you put the the fragment on a side and the wheat on the other side.
2-To weigh 2 pounds, then u put the rock fragment on a side togther with the amount of wheat that equals one pound on one side and start weighing.
3- To weigh 3 pounds, you take the amount of weight u got from 2 , which equals 2 pounds beside the rock fragment and put them on the same side and start weighing.
4- You repeat the same stuff and so on............
I don't understand .............this is too easy there seems to be something wrong.
