Which of the products shown had the lowest value of sales per non-European store and which had the highest value of sales per European store?

Step 1 – calculate each product’s average sales per European store
DE45 = 21,000/26 = 808
PU20 = 30,000/19 = 1,579
AE25 = 24,500/11 = 2,227
PU10 = 18,700/9 = 2,078
FD24 = 14,700/13 = 1,131

Step 2 – calculate each product’s average sales per non-European store
DE45 = 35,000/14 = 2,500
PU20 = 20,000/9 = 2,222
AE25 = 13,000/6 = 2,167
PU10 = 24,000/5 = 4,800
FD24 = 9,000/7 = 1,286

Thus the correct answer is (C), FD24 (non-European); AE25 (European)

If the costs are put into order of decreasing size, in which two years is the order the same?

Put each year’s costs into size order:
2006 = Labour, Production, Supply Chain, IT, Overheads
2007 = Production, Labour, IT, Supply Chain, Overheads
2008 = Labour, Production, IT, Supply Chain, Overheads
2009 = Production, Labour, Supply Chain, IT, Overheads

Tip: at this stage you could see that none of the years match so given that there is no
"none of these" option you could gamble that 2010 will have the same order as one of the
others, and thus go for answer (C).

Carrying on for the remaining year:
2010 = Labour (1,077), Production (1,058), Supply Chain (688), IT (618), Overheads
(412)

Thus the correct answer is (C), 2006 and 2010

If 2009’s total costs were £250,000, what were the Production costs?

The information that you need is shown in the graph.
Production costs = 26% = £250,000 x 26% = £65,000
Thus the correct answer is (D), £65,000

Which cost or costs on their own represented more than 17% of the total costs in 2010?

The information that you need is shown in the table.

Step 1 – Calculate the total cost across the 4 quarters for 2010
Q1 total = 914
Q2 total = 915
Q3 total = 1,014
Q4 total = 1,010
2010 Total costs = 3,853

Step 2 – Calculate the % that each individual cost represented
Overheads = (104 + 105 + 102 + 101) / 3,853 = 10.7%
Supply chain = (186 + 174 + 162 + 166) / 3,853 = 17.9%
Labour = (248 + 245 + 319 + 265) / 3,853 = 28.0%
I.T. = (149 + 138 + 140 + 191) / 3,853 = 16.0%
Production = (227 + 253 + 291 + 287) / 3,853 = 27.4%

Thus the correct answer is (D), Supply chain, Labour and Production

If the total 2010 costs represent a 5% increase on the total 2009 costs, what were the total 2009 costs (to the nearest £million)?

The information for 2010 that you need is shown in the table.

Step 1 – calculate the total costs for 2010
Q1 total = 914
Q2 total = 915
Q3 total = 1,014
Q4 total = 1,010
Total = 3,853

Step 2 – calculate the total costs for 2009
3,853 = 105% x (2009 total costs)
2009 total costs = 3,853 / 1.05 = 3,669

Step 3 - to the nearest £million
3,669 (£10,000s) = £37 million

Thus the correct answer is (D), £37 million
