Assalam u Alaikum,
I live in a village and I am a shopkeeper. I sell rice sold in complete kg's ( i.e 1 kg, 12 kg etc. i.e only whole numbers). The problem is that I don't have an electronic weighing machine and only have a traditional weighing machine (with two panels).
A friend of mine has told that I need only "4 different weights" to sell my rice if they are to be sold in the range of 1 to 40 kg. This is perfectly acceptable to me. Can you guess those 4 weights that I need to have so that I can weight anything between 1-40 kg? I am not allowed to use the weighing machine twice to weight a single request. i.e If someone wants to have 37 kg. of rice I will use these four weights (or less) to weigh 37 kg. of rice for him and not use the the weigh machine twice.
