At the beginning
At the beginning of 2015, an airport changed concession vendors from FlightDelight to AirFare. By the end of the 2015, concession sales were up nearly 10%, but effective January 2016 the airport cancelled the AirFare contract and returned to using Flight Delight, citing low sales as the sole reason.
Which of the following, if true, most serves to reconcile the discrepancy above?
A. The city’s other major airport saw a sales increase of 15% for the year 2015.
B. Travelers rated AirFare’s variety of offerings significantly lower than they had rated the variety of offerings from FlightDelight.
C. For the year 2015 several airlines that fly routes in and out of the airport overhauled their in-flight menus.
D. The number of flights departing from the airport was 30% higher in 2015 than it had been in 2014.
E. AirFare’s sales were slow over the first half of 2015 because it closed multiple points of sale to make renovations.
My Ques- Please help in explaining why D is correct because it does not talk about 2016
Let’s plug in numbers here (not required to arrive at the answer though)
Assume sales at beginning of 2015 = 100
Assume number of flights departing from airport in 2014 = 20
Sales figure per flight = 100/20 = 5
Number of flights departing from airport in 2015 = 26
Expected sales at end of 2015 = 26*5 = 130
But sales at end of 2015 = ~110
Do you see the problem here? Even though the flights increased by 30%, sales did not increase as expected
