a shopkeeper
a shopkeeper uses two kinds of balace.
one weights 10% and other is 10% less.
he uses first one while buying goods and second one while selling goods so that he can make profit.
now how much pecentage does he get on total transaction for the same goods?
we frens tried in our way and we conclude on differen percentage. Can anyone solve these problem with good reasonings.
best regards

Re: a shopkeeper
He is going to use the scale that weighs on the light side to buy goods. Let's say the goods really weight 10 pounds. He's going to pay for only 9 pounds but he's going to sell them as 11 pounds. That's a 2 pound difference or 22% gain (2/9).
