How to weigh any weight from 1 to 40 using four weights whose sum is 40KG?

+2 votes

A merchant has a 40 kg weight which he used in his shop. Once, it fell from his hands and was broken into 4 pieces. But surprisingly, now he can weigh any weight between 1 kg to 40 kg with the combination of these 4 pieces.

So question is, what are weights of those 4 pieces..?
