Data Interpretation

Detailed Solution

134. Step 1 – calculate the total Week 1 and Week 3 sales across the 5 Stores
Week 1: 20 + 30 + 25 + 15 + 5 = 95
Week 3: 35 + 40 + 24 + 12 + 9 = 120
Step 2 - calculate the total Week 1 and Week 3 targets across the 5 Stores
Week 1: 15 + 20 + 20 + 10 + 10 = 75
Week 3: 35 + 35 + 30 + 15 + 15 = 130
Step 3 – calculate the difference for Weeks 1 and 3
Week 1: 95 – 75 = 20 over target
Week 3: 120 – 130 = 10 under target
Thus the correct answer is (D), 20 over target (Week 1); 10 under target (Week 3

135. Step 1 – calculate each Store’s total sales
Use the Actual sales figures for each of the 3 weeks, as follows:
Redcliff 20 + 20 + 35 = 75
Ather 30 + 40 + 40 = 110
Wilkington 25 + 18 + 24 = 67
Trew 15 + 14 + 12 = 41
Tunston 5 + 6 + 9 = 20
Step 1 – calculate each Store’s average sales per sales staff member, as follows:
Redcliff 75 / 8 = 9.4
Ather 110 / 9 = 12.2
Wilkington 67 / 5 = 13.4
Trew 41 / 8= 5.1
Tunston 20 / 6 = 3.3
Thus the correct answer is (C), Wilkington

136. Step 1 – calculate the new staff numbers
Redcliff 8 – 2 = 6 staff
Ather 9 – 2 = 7 staff
Wilkington 5 – 1 = 4 staff
Trew 8 – 2 = 6 staff
Tunston 6 – 1 = 5 staff
Step 2 – calculate the average target per staff member
Average = target / total number of staff = 168,000 / 28 = £6,000
Thus the correct answer is (B), £6,000

137. Step 1 – calculate each Region’s sales
Eastern Region’s sales = 2 x 120,000 / 3 = 80,000
Northern + Southern Regions’ sales = 80,000 x 2 = 160,000
Step 2 – calculate the total sales
120,000 + 80,000 + 160,000 = 360,000
Thus the correct answer is (D), £360,000

138. Step 1 – calculate the total sales
Use the Week 1 and Week 3 sales totals from Question 134
Week 2 sales = 20 + 40 + 18 + 14 + 6 = 98
Total sales = Week 1 + Week 2 + Week 3 = 95 + 98 + 120 = 313
Step 2 – calculate the amount saved
313 x £9.50 = £2,973.50
Step 3 (to the nearest £100)
£2,973.50 = £3,000
Thus the correct answer is (A), £3,000
Tip: when summing numbers from a column or row, be careful not to take numbers from an adjacent category. It is also a good idea to enter the numbers as you go straight into your calculator, instead of writing out the sum on your rough paper then performing the calculation. This will reduce the number of stages in your working and save time and reduce the potential for input errors.
