Question 1
Green Apparel, a large clothes retailer with high street shops and an online shopping site, has a different
dress code policy for its admin and operational staff. The dress code for admin staff is suit and shoes and for operational staff is top, trousers, and shoes, all provided by the company. Green Apparel employs 330 staff as shown in the left side of Table 1. The right side of the table shows the cost of each clothes item by purchase quantity (which is not affected by clothing size). Although different types of shoes are available, their cost is assumed to be the same, as given in Table 1.

office employees plus 2/3 of the delivery and half of the warehouse employees are based, in a new
specific colour (same cost per item applies)? [3 marks]
d. If shoes of the operational staff need changing twice a year and of admin staff only once a year, how
much does Green Apparel spend on shoes per year? [2 marks]
e. Green Apparel is considering updating its logo and has budgeted £10,000 for uniform changes. The

Question 3
Renoir plc is considering investing in a new machine for its packaging plant.

and is expected to have a scrap value of £1,000. Their expected cashflows are given in Table 2.
Calculate and compare the Accounting Rate of Return (ARR) and Payback Period (PP) for both
machines. [10 marks]
Table 2: Expected cashflows (before depreciation) of machines A and B
Year Machine A Machine B
0 (£5,500) (£5,000)
1 £2,000 £1,400
2 £2,000 £1,600
3 £2,000 £2,000
4 £2,000 £2,000
5 £2,000 £1,800
5 £600 £1,000

appropriate calculations, can you help the management of Renoir plc to make a decision about this
new machine they want to invest in? [10 marks]
c. The company is also considering machine C which has an expected life of 5 years and is expected to
generate annual cashflows of £2,500. Using a discount rate of 10%, what is the maximum amount the

Question 4
Monet plc has an opportunity to invest in a plant for the manufacture of reusable water bottles, the demand

ګ Overhead costs are not expected to be affected by the decision.
ګ The cost of capital for such a project is estimated to be 10% p.a.
ګ The project is not expected to require any additional working capital.
ګ In the interest of simplicity, taxation will be ignored.
ګ Assume, also in the interest of simplicity, that all cash flows occur at year ends
You are asked to undertake a sensitivity analysis of the above project for the following factors:
1. Initial investment [5 marks]
2. Sales price per bottle [5 marks]
3. Variable cost per bottle [5 marks]
4. Sales volume [5 marks]
5. Project discount rate [5 marks]
Summarise your results in a sensitivity analysis table advising the company on the most sensitive factor. [10
