Answer
The trick to answer GMAT Data sufficiency question is to convert the question to statements, so that statement 1 and 2 can be tested, and the appropriate answer choices selected.
The question gives us information about Occupancy rate broken down from Friday to Sunday. What we need to find is the revenue earned from Friday to Sunday
Revenue = Number of Tickets x Price of Each Ticket
Statement 1 explains about the two types of ticket types – Silver and Gold, and the price of each
Silver = $35
Gold = $45
Revenue = Number of Silver Tickets x $35 + Number of Gold Tickets x $45
Since we don’t have information about the total seats and how it is divided between Gold, and Silver Category, we can’t find the revenue.
Statement 1 is insufficient
Eliminate A and D
Statement 2 gives us information that Screen 1 = Screen 2 = Screen 3 = 500
Total Seats = 1500
Since we don’t have information about the cost of each ticket, we can’t find the revenue.
Eliminate B
Now it is the time to combine Statement 1 and Statement 2
Screen 1 = Screen 2 = Screen 3 = 500
Silver = $35
Gold = $45
Occupancy Rate
Friday Saturday Sunday
Screen 1 85% 90% 90%
Screen 2 65% 50% 65%
Screen 3 50% 20% 15%
Although we have almost all information, one crucial information is missing – how silver and gold tickets are divided in a screen. Therefore combining statements does not help.
