What was the percentage change in Graff's revenue from the first to the fourth quarters?

The length of a quarter of a year will always be three months. A quarter could be any three consecutive months of the year; keep in mind that the first quarter isn't always going to be from January to March. This is because businesses have various year ends.

Correct! Wrong!

Step 1: Determine Graff's first-quarter revenue, which is 15,000

Step 2: Obtain Graff's fourth-quarter revenue, which is $30,000

Step 3: Take the newest quarter out of the oldest:

30,000 - 15,000 = 15,000

Step 4: Subtract this from the 'oldest' figure, the first quarter figure.

15,000 / 15,000 x 100

= 100%

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?

Correct! Wrong!

First, the percentage of canceled flights at Gatwick Airport to all other airports is requested. Write the following down in ratio format to begin:

20 : (30 + 20 + 15)

20 : 65

Step 2: Calculate the ratio by dividing 65 by 20:

65 ÷ 20 = 3.25

1 : 3.25

How many more flights were cancelled at Stanstead between November and December and January and February, on average?

Correct! Wrong!

Step 1: Determine how many flights were canceled in November and December.

Dec + Nov + 10 = 25

Step 2: Determine how many flights were canceled in January and February.

Jan + Feb equals 35 + 45 + 80.

Step 3: Divide the Nov/Dec figure by the Jan/Feb figure after subtracting the Jan/Feb figure:

(80 - 25) ÷ 25 x 100 = 220%

How many of the cancelled flights in February originated from Gatwick Airport?

Correct! Wrong!

Gatwick's cancellations as a percentage of all cancellations at all 3 airports in February is as follows:

20 / (15+20+45) x 100

= 25%

What was the actual revenue generated by Binders during the three-month period from October to December, assuming the report overestimated revenues by 15%?

Correct! Wrong!

Step 1: Obtain the following amount from the sale of binders during the quarter ending in December: £35,000.

Step 2: This revenue estimate is 15% inflated. Therefore, it is 115%. 100% are required in the question. Simply multiply by 100 and divide by 115:

£35,000 ÷ 115 x 100 = £30,435

Tip: To determine the original non-overstated amount, add the "X" percent overstatement to 100%, then divide by 100%.

Correct! Wrong!

First, determine an 80% reduction in the number of flights canceled in January:

30 × (1-0.8) = 6

Second step: Subtract this amount from the March amount.

10 - 6 = 4
