Given  

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:

The cost of medium quality mangoes is half that of good mangoes.  

Let medium quality mangoes be x and good good quality will be 2x

So 40 + 80 = 120 kg

So x will be 40 and 2 x will be 80.

Now 10 % less than that of good quality will be 1.8 x.

So total cost price will be 160 x and total selling price is 1.8 x x 120 = 216 x

Now total selling price will be 216 x

So for 200 it will be 216 x

Now for 100 it is 108

Therefore there is a overall profit of 8%.
