If the cost price of 50 oranges is equal to the selling price of 40 oranges, then the profit per cent is
A). 5 %
B). 15 %
C). 25 %
D). 35 %
25 %
Because the cost price of 50 oranges = Selling price of 40 oranges
The profit is 10 oranges out of 40 oranges;
therefore, the profit percent = 10 × 100/40 = 25%.
