A shopkeeper labeled the price of his articles so as to earn a profit of 20% on the cost price. He then sold the articles by offering a discount of 10% on the labeled price. What is the actual percent profit earned in the deal? Choose the correct option:  A) 18%  B) 20%  C) 17%  D) 19%  E) None of these
Explanation:   Let the CP of the article = Rs.100.   Then labeled price = Rs.120.   SP = Rs.120- 10% of 120 = Rs.120-13 = Rs.118.   Gain = Rs.118 â€“ Rs.100 = Rs.18   Therefore, gain/profit percent = 18%.   Answer: Option 19%
