If the circus were to sell all of its 220 tickets for this month's performance at its usual price, the revenue from sales would be 10% greater than that collected last month. If the circus raised the ticket price by 5% and sold only 200 tickets as a result, what percent less would last month's revenue be compared to this month's revenue?	Pick one.
A) 2  B) 5  C) 100/21  D) 110/20  E) 9/4
Last months revenue can be calculated as 220x / 1.10 = 200x   Now consider the next statement - &gt; if the price of ticket is hiked by 5% the new price is 1.05 x.   So the new revenue when only 200 tickets are sold 220  / 1.10= 
<gadget id="calculator">220  / 1.10</gadget>
<output>200</output>
200x   Now consider the next statement - &gt; if the price of ticket is hiked by 5% the new price is 1.05 x.   So the new revenue when only 200 tickets are sold= 200 * 1.05= 
<gadget id="calculator">200 * 1.05</gadget>
<output>210</output>
210x.   We need to find the percentage difference ; so we have (new-old/new*100) 210x-200x/210x*100= 100/21   Answer: 100/21
