A factory has 15 machines of equal efficiency in its factory. The annual manufacturing costs are Rs.42,000 & establishment charges are Rs.12,000. The annual output of the company is Rs.70,000. The annual output and manufacturing costs are directly proportional to the number of machines. The shareholders get 12.512.5 profit, which is directly proportional to the annual output of the company. If 7.147.14 machines remain closed throughout the year, then the % decrease in the amountof profit of the shareholders would be? Choose the correct choice from the following choices.
A) 12.5%	B) 13.5%	C) 14%	D) 15%	E) 16%
Option(B) is correct   Original profit   = 70,000−42,000−12,000=16,00070,000−42,000−12,000=16,000   If 7.14%7.14% of 14 i.e. one of the machines closed throughout the year, then change in profit will be:   =1314×[70,000−42,000]=1314×[70,000−42,000]   =14,000=14,000   Thus, decrease in the profit %%   =200016000×100=200016000×100   =12.5%   12.5%
