A stadium manager expected 13,200 spectators to attend a sporting event. If everyone who bought a ticket attended the event, how many full-price tickets were sold?
(1) The number of full price tickets sold was equal to 81 percent of the number of spectators expected by the stadium manager
(2) Of the 11,880 people who attended the event, 90 percent had bought full-price tickets.
Expected spectator population = 13200
The actual population which attended is not known. But, the number of people who bought the tickets attended the event without fail.
We need to find : # full price tickets sold .
Statement 1:
(1) The number of full price tickets sold was equal to 81 percent of the number of spectators expected by the stadium manager
# full price ticket = 81%*(13200)
= 10692
Hence, Sufficient Statement 2:
(2) Of the 11,880 people who attended the event, 90 percent had bought full-price tickets.
Given that 11880 attended the event, this means the number of people who bought the tickets for the event = 11880.
# full price ticket = 90%*(11880) = 10692
Hence, Sufficient
Each statement is individually Sufficient to answer the question. Hence
