In a shop, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, find out approximately what percentage of the selling price is the profit?  Choose the correct choice from the following:
A) 180 % B) 120 % C) 90 % D) 80 % E) 70 %
Let the CP = 100   Profit=(320 / 100) ×100=320   SP=CP+Profit=100+320=

420   If the cost increases by 25%, New CP=(125/100) ×100=125   Selling Price is constant, hence New SP=420   Profit=SP–CP=420–125=295   Required Percentage =(295/420)×100   =2950 / 42   =1475 / 21 ≈ 70   ANSW70 %R:70 %
