What is the difference in average monthly sale values between the most and the least expensive packages?


Step 1 – the table shows the most (£40 per month) and least expensive packages (£25 per month)
Step 2 – calculate the difference in monthly average monthly packages sold

  Platinum package Bronze package
Central 4,540 5,425
Northern 4,725 5,846
Southern 4,584 5,428
Western 4,682 4,869
Eastern 4,884 4,592
     
ANNUAL TOTAL 23,415 26,160
MONTHLY AVERAGE 951.25 2180
VALUE 1951.25 x £40 = £78,050 80 x £25 = £54,500

Difference = £78,050 - £54,500 = £23,550

So the correct answer is £23,550

What is the difference in revenue between the package with the lowest number of sales and the package with the highest number of sales over the 12 month period, across all regions combined?


Step 1 – find the highest selling and the lowest selling number of new mobile phone contracts by totaling sales across all 5 regional stores for each package

  Platinum
package
Gold package Silver package Bronze package
Central 4,540 4,854 5,083 5,425
Northern 4,725 5,005 5,382 5,846
Southern 4,584 5,123 5,759 5,428
Western 4,682 4,759 4,956 4,869
Eastern 4,884 5,256 4,982 4,592
TOTAL 23,415 24,997 26,162 26,160

Step 2 – calculate the difference in sale values between the Silver and Platinum
packages
Silver package = 26,162 x £30 = £784,860
Platinum package = 23,415 x £40 = £936,600
Difference = £936,600 - £784,860 = £151,740

So the correct answer is £151,740

A day trader bought 50,000 Tombe shares at last month’s low, received the Tombe dividend and then sold all these shares at last month’s high. What was the approximate percentage gain or loss?


Step 1 – Calculate the cost to buy the shares
50,000 x £1.70 = £85,000

Step 2 – Calculate the profit from the change in share price
£2.03 x 50,000 = £101,500
£101,500 - £85,000 = £16,500

Step 3 – add the dividend
£16,500 + (0.10 x 50,000) = £21,500

Step 4 – calculate the %
21,500/85,000 = 25.3%

Tip: notice that one of the multiple choice options is the answer if you forgot to add the
dividend (19.4% profit). This is called a distractor.

So the correct answer is 25.3% profit

Which share has changed in price by the largest amount since the previous day?


Step 1 – Calculate the Previous Day’s Price for each share listed as an answer option.
Previous Day’s Price = Previous Day’s Company Value / Total number of Company Shares.

Relf plc= 240 / 80 = £3.00
Studt Systems = 171 / 55 = £3.11
Xan Inc. = 28 / 12 = £2.33
IWE Ltd = 200 / 114 = £1.75

Step 2 – Calculate the difference with the Current price for each share, as follows;
Relf plc = 3.00 - 2.75 = 0.25
Studt Systems = 3.11 – 3.00 = 0.11
Xan Inc. = 2.33 - 2.28 = 0.05
IWE Ltd = 1.75 - 1.48 = 0.27

So the correct answer is IWE Ltd
