Detailed Solution

47. Step 1 – calculate Simon and Jessica’s total mileage in August
Simon = 60p x 70 x 25 = £1,050
Jessica = 44p x 85 x 30 = £1,122
Step 2 – calculate Simon and Jessica’s combined travel allowance payment
£1,050 + £1,122 = £2,172
Thus the correct answer is (D) £2,172

48. Step 1 – calculate the % change for Jessica and Kim
Jessica = 81/90 = 10% decrease
Kim = 70/62 = 12.9% increase
Step 2 – calculate each Sales Manager’s number of visits for November
Jessica = 81 x 90% = 73 visits
Kim = 70 x 112.9% = 79 visits
Thus the correct answer is (D), 73 visits (Jessica); visits 79 (Kim)

49. Calculate the 85% and 115% figures for each Sales Manager
Simon (to the nearest whole visit)
95 x 85% = 80.75 = 81
95 x 115% = 109.25 = 109
Note that already we have eliminated 3 of the possible 5 answers.
Jessica:
81 x 85% = 68.85 = 69
81 x 115% = 93.15 = 93
Kim
70 x 85% = 59.5 = 60
70 x 115% = 80.5 = 81
Thus the correct answer is (D), 81–109 (Simon); 69–93 (Jessica); 60–81 (Kim)
Tip: note the difference between “round to the nearest whole visit” and “give the number of complete visits”. This is the difference between rounding to the nearest integer (could be up or down) and ignoring any part-complete events (will always be rounding down).

50. Step 1 – Let x = Jessica’s average mileage per client visit
July visits = 70 = 3,500 / x
X = 3,500 / 70 = 50 miles per visit
Step 2 – calculate Simon’s average mileage per client visit
50 – 10 = 40 miles per visit
Step 3 – calculate the total number of miles Simon travelled in July
40 x 65 = 2,600 miles
Thus the correct answer is (B), 2,600 miles

51. Calculate each Sales Manager’s client sales for June, as follows:
Simon 50 visits in June 50 x £145 = £7,250
Jessica 45 visits in June 45 x £135 = £6,075
Kim 60 visits in June 60 x £125 = £7,500
Thus the correct answer is (A), Kim (most); Jessica (least)
