A shopkeeper labeled the price of his articles so as to earn a profit of 40% 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 choice from the following answers:
A) 26 %	B) 20 %	C) 17 %	D) 18 %	E) none of these
