A comedian is playing two shows at a certain comedy club, and twice as many tickets have been issued for the evening show as for the afternoon show. Of the total number of tickets issued for both shows, what percentage has been sold?
(1) A total of 450 tickets have been issued for both shows.
(2) Exactly 3/5 of the tickets issued for the afternoon show have been sold, and 1/5 exactly of the tickets issued for the evening show have been sold
Dear
SajjadAhmad,
I'm happy to respond.
This question makes the somewhat arcane distinction between "tickets issued" and "tickets sold," but at least they are consistent with terminology through the question.
We need to know both the total number of tickets issued, and the percent sold of those issued. Let's say that T tickets were issued for the morning, and 2T, for the evening.
Statement #1: 450 Tickets
We know T = 150 and 2T = 300, but we have no idea how many have been sold.
Not sufficient.
Statement #2:
Exactly 3/5 of the tickets issued for the afternoon show have been sold, and 1/5 exactly of the tickets issued for the evening show have been sold.
What we have been given is "ratio information" and what we are asked to find is "ratio information." This may well be enough: we don't necessarily need to know exact counts to answer a question about ratios/percents. For more on these ideas, see:
GMAT Quantitative: Ratio and ProportionsTotal number of tickets issued = T + 2T = 3T
Sold in afternoon show: = (3/5)T
Sold in evening show = (1/5)(2T) = (2/5)T
Sold, total = (3/5 + 2/5)T = T
Percentage sold = T/(3T) x 100% = (1/3) x 100%
We don't need to compute further, although it's probably obvious that it's 33.33%. We have a numerical answer to the prompt. This statement is
sufficient.
