A competitor airport operator called Vefy Flights operates a different airport with half the average Year 1 weekly number of passengers operating from 3 terminals. What is Vefy Flights’s average weekly number of passengers per terminal (to the nearest 1,000)?


Step 1 – calculate the total number of Terminal A-E passengers.
Total number of Terminal A-E passengers = 676.

Step 2 - calculate Vefy Flights’s average weekly number of passengers
676 x 0.5 = 338

Step 3 – calculate Vefy Flights’s average weekly number of passengers per terminal
338 / 3 = 112.667 (1,000’s)
= 112,667
= 113,000 (to the nearest 1,000)

So the correct answer is (B), 113,000

In Year 2 each passenger spends on average £4.25 in Terminal C’s shops. How much is the average weekly revenue for Terminal C’s shops in Year 2 (to the nearest £10,000)?


Step 1 – calculate Year 2 passenger total for Terminal C
(62.9 + 63.1) x 101.5% = 127.89
In 1,000's = 127,890

Step 2 – calculate the average weekly revenue generated
127,890 x £4.25 = £543,532.5 (£540,000 to the nearest £10,000)

So the correct answer is (B), £540,000

For Year 1 what was the average weekly difference between male and female passengers per terminal?


The information that you need is shown in the table.

Step 1 – calculate the total difference between the weekly numbers of male and female
passengers
(52.9 – 52.7) + (66.6 - 66.5) + (62.9 – 63.1) + (77.1 – 76.9) + (78.8 – 78.5) = 0.6

Step 2 – calculate the average difference
= 0.6 / 5 (1,000s)
= 0.12 (1,000s)
= 120 more male passengers

So the correct answer is (E) 120 more males

104)

Which terminal had the highest number of passengers per week in Year 2?


The information that you need is shown in both the table and the graph.

Step 1
Given Year 2’s 1.5-2.5% increases in passenger numbers, save time by considering only
which terminals have the highest number of passengers per week in Year 1. This is
Terminal D and E.

Step 2
Calculate Year 1’s total passengers for Terminals D and E (by adding male and female
passenger numbers):
Terminal D = 77.1 + 76.9 = 154
Terminal E = 78.8 + 78.5 = 157.3

Step 3 - calculate Year 2’s totals for these Terminals:
Terminal D = 154 x 102% = 157.08
Terminal E = 157.3 x 98% = 154.15
So the correct answer is (D), Terminal D

The total 2011 Marketing Budget for all five Brands is to be cut by a quarter in 2012. In £, what is the 2012 Marketing Budget? (to the nearest £100,000)?


Step 1 – calculate the 2012 marketing budget

2011 marketing budget (from previous question) = 1135 ( 10,000s)
2012 marketing budget = 11.35 million x 75% = 8.5125 million

Step 2 – convert into £
8,512,500 / 1.2 = £7.094 million

Step 3 – put answer into the nearest £100,000
£7.1 million

So the correct answer is £7.1 million
