Question 1: What was the percentage change in Graff's revenue from the first to the fourth quarters?
- 25%
- 50%
- 75%
- 100% (Correct answer)
Correct answer: 100%
To determine the percentage change, you would compare Graff's revenue in the first quarter to its revenue in the fourth quarter. If, for example, the revenue doubled from the first to the fourth quarter (e.g., from £100 to £200), the calculation would be ((£200 - £100) / £100) * 100 = 100%. This indicates a doubling of revenue.
Question 2: How many flights were cancelled at Gatwick Airport in November as a ratio of all the flights canceled at all three airports in that month?
- 1:7.67
- 1:4.40
- 1:3.25 (Correct answer)
- 1:3.67
Correct answer: 1:3.25
To calculate this ratio, you would first identify the number of flights cancelled at Gatwick Airport in November. Then, sum the total number of flights cancelled at all three airports (Gatwick, Stanstead, and the third unnamed airport) for November. The ratio is then Gatwick cancellations to total cancellations, simplified to its lowest terms, such as 1:3.25.
Question 3: How many of the cancelled flights in February originated from Gatwick Airport?
- 25%
- 20%
- 35%
- 25% (Correct answer)
Correct answer: 25%
To find the percentage of cancelled flights from Gatwick in February, you would divide the number of cancelled flights specifically from Gatwick in February by the total number of cancelled flights from all airports in February. Multiplying this result by 100 gives the percentage. For instance, if Gatwick had 20 cancelled flights out of a total of 80 in February, it would be (20/80) * 100 = 25%.
Question 4: How much money did Moen make on average each month from January to June?
- £7,500
- £8,333
- £27,500
- £9,167 (Correct answer)
Correct answer: £9,167
To calculate Moen's average monthly earnings from January to June, you would sum the total revenue generated by Moen for each of those six months. Once the total sum is obtained, divide it by six (the number of months) to find the average. For example, if the total revenue was £55,002, the average would be £55,002 / 6 = £9,167.
Question 5: What was the actual revenue generated by Binders during the three-month period from October to December, assuming the report overestimated revenues by 15%?
- £35,000
- £29,750
- £30,435 (Correct answer)
- £25,500
Correct answer: £30,435
If the reported revenue of Binders for October to December was overestimated by 15%, it means the reported figure represents 115% of the actual revenue. To find the actual revenue, you divide the reported revenue by 1.15. For example, if the reported revenue was £35,000, the actual revenue would be £35,000 / 1.15 = £30,434.78, which rounds to £30,435.
Question 6: How many more flights were cancelled at Stanstead between November and December and January and February, on average?
- 25%
- 200&%
- 220% (Correct answer)
- 875%
Correct answer: 220%
First, calculate the average number of cancelled flights at Stanstead for the November-December period. Then, calculate the average for the January-February period. To find the percentage 'more' flights, subtract the Nov-Dec average from the Jan-Feb average, divide by the Nov-Dec average, and multiply by 100. For example, if the Nov-Dec average was 10 and Jan-Feb was 32, the increase is ((32-10)/10)*100 = 220%.
