QUESTION 2
XYZ Ltd sells a Table with a fixed quoted price of £50. Total sales are related to the number of products sold using the following formula
𝑇𝑜𝑡𝑎𝑙 𝑠𝑎𝑙𝑒𝑠=𝑄𝑢𝑜𝑡𝑒𝑑 𝑝𝑟𝑖𝑐𝑒 ×𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑠 𝑠𝑜𝑙𝑑
For example, during the 12-month period to 31 December 2007, the company sold 15,000 tables, producing total sales of £75000
The company estimates the impact of economic recovery as follows:
- Slow recovery – with a probability of occurrence of 0.60, this will result in a 30% decline in the number of products sold from the previous 12 months.
Fast recovery – with a probability of occurrence of 0.40, this will result in a 10% increase in the number of products sold from the previous 12 months.
Required:
- a) Calculate total sales for the 12-month period ended 31 December 2008 under each scenario (16 marks)
- b) Calculate the company’s expected total sales for the 6-month period ended 31 December 2008 (9 Marks)
QUESTION 2 (ANSWER SHEET)
a)
Slow recovery | Fast recovery | |
Expected number of products sold | × = | × = |
Fixed quoted price (£) | ||
Expected sales (£) | ||
Probability of occurrence |
b)
Expected total sales for the 6-month period ended 31 December 2020 |
Expected total sales = ( × ) + ( × )
Expected total sales =
