If a 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 were to raise the ticket price by 5% and sell 200 tickets, what percent less would last month's revenue be compared to this month's revenue?

A. 2

B. 5

C. \(\frac{100}{21}\)

D. \(\frac{110}{20}\)

E. \(\frac{9}{4}\)

This question is

majorly a Word-Problem. We have to be very attentive to solve this one.

Let's go one by one:

Had circus sold all the 220 tickets at it's usual price (say 10), it would have 220*10= 2200 Revenue, which is in turn 10% higher to the last month.

=> Last month Revenue = 2200/1.1= 2000.... (1)

Now, Tickets' price are raised by 5% i.e. new ticket's price is 10.5 & Total Tickets are 200

=> This month's revenue = 200*10.5= 2100

Now this is 2100-2000= 100 more than last month's revenue

=> (100/2100)*100 = 100/21 % less would be last month's revenue from this month.

C is the answer.
