Ram adjusted his electronic weighing scale in a typical way. But he gives a discount of 10% in every transaction. His weighting scale shows 5 kg for 4 kg. What is the actual profit % when the displayed weight is 10 kg, if he sells the commodity at its cost price?
Let Ram buy 10 kg for Rs 100
Since 4kg shows 5 kg in weighting scale
⇒ when he sells 8 kg weighting scale shows 10kg find he gives 10% discount
So, he sold 8kg for Rs 90 and had bought if for Rs 80
⇒ Profit %=1080×100=12.5%
