Story 10dollars = 4kg wheat !
My usual supermarket to buy 10 dollars is 4 kg of wheat. until one day I bought 10 dollars wheat but that day they sold me 240kg! Surprisingly I hastily add 20 dollars to buy wheat and they sold me a total of 480kg. Next I used to donate all the wheat and then they sue me, demanding I pay back the wheat it. The question is who is right?
