In a market, the price of medium quality mangoes is half that of good mangoes. A shopkeeper buys 80 kg good mangoes and 40 kg medium quality mangoes from the market and then sells all these at a common price which is 10% less than the price at which he bought the good ones His overall profit is
8%
Let the good quality mangoes be priced at Rs. 100/kg.
Medium quality mangoes' price = Rs. 50/kg
Profit percentage =[{(80+40)×90−(40×50)−(80×100)}{(40×50)+(80×100)}]×100=[(1080010000)−1]×100=8
