1 .A fruit seller buys 240 apples for ` 600.
Some of these apples are bad and are thrown
away. He sells the remaining apples at
` 3.50 each and makes a profit of ` 198. The
% of apples thrown away are ?
The cost price of 240 apples = `600
Profit = `198
Total selling price= 600 + 198 = `798
The selling price of each apple = `3.50
So, quantity sold = $798\over3.5$=228
Percentage apple thrown= $240-228\over240$x100
