Puzzle

Those of you who are good in solving mathematical puzzle, here is an interesting one.

"There are 10 boxes. Each box contains 10 balls of identical shape , size and color.
Balls in 9 out of 10 boxes weighs 10 grams each. Only one of the boxes contains balls weighing 9 grams each instead of 10 grams. You have to identify the box which contains balls weighing 9 grams only. You are provided with a weighing balance with weights of 10 grams and 1 grams only. The only condition is that once you put number of balls on the weighing balance, you cannot change it. You are however, allowed to change the weights"

I think for weighing we take one ball from each box and weigh it...weighing can be done by putting 10 gm one side and ball and 1 gm on the other side?

I am afraid Renu, it is not correct.
Sorry. You may try again to solve it.
