A retailer purchases pants from a wholesaler and then sells the pants in his store at a retail price that is 50 percent greater than the wholesale price. If the retailer decreases the retail price by 20 percent this will have the same effect as increasing the wholesale price by what percent?	Choices
A) 26	B) 20	C) 42	D) 44	E) 25
Answer: B= 20.   Assume Rs. 100 to be the price at which the retailer buys from wholesaler.   50% increase makes Retail price = 150.   Now 20% decrease -&gt; (1-20/100) * 150 = 120.   Now compared to the wholesale price of 100, 20% increase is what will have the same effect as increasing the wholesale price.
