John brings 1000 chocolates for his sister and ten boxes as well. He asks his sister to place the chocolates in the boxes in a manner that if he asks for any number of chocolates, she can give a box or a combination of boxes to him without taking out any. If she can do it, all 1000 chocolates will be hers.

How would she accomplish the same ?
