Select the correct option
A) 30%  B) 40%  C) 50%  D) 100%  E) 200%
Here, selling price of 10 m cloth is obtained as profit.   Profit of 10 m cloth = (S.P. of 15 m cloth) – (C.P. of 15 m cloth)   Selling price of 5 m cloth = Selling Price of 15 m of cloth   Let cost of each metre be Rs. 100.   Therefore, cost price of 5 m cloth = Rs. 500 and S.P. of 5 m cloth = Rs. Rs. 1500   Profit% = 1000/500 × 100 = 200%   Profit of 200% was made by the merchant.   200%
