Question
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
Options
6%
8%
10%
12%
Solution
Let the cost of good mangoes be 2x per kg. The cost of medium mangoes be x per kg.
CP of good mangoes = 160x
CP of medium mangoes = 40x
His selling price = 0.9*2x = 1.80x
Therefore, total revenue generated by selling all the mangoes = 120*1.8x = 216x
Hence, the profit % = $\frac{16x}{200x} * 100$ = 8%
