Section A: Basic Concepts and Calculations (Questions 1–8) [16 marks]
1. State the basis on which inventory should be valued according to the prudence concept. [1]
2. Define "net realisable value" of inventory in your own words. [2]
3. Bright Store had opening inventory of 4,000,purchasesof26,000, and closing inventory of $5,000. Calculate the cost of sales. [2]
4. A business had opening inventory 3,200,closinginventory4,800, and cost of sales $30,000. Calculate the purchases for the year. [2]
5. State one reason why a business should not overstate its closing inventory. [1]
6. Goods with cost price 900haveanetrealisablevalueof700. State the value at which they should be reported in the Statement of Financial Position. [1]
7. Explain why inventory is recorded as a current asset. [2]
8. A shop's average inventory is 6,000andcostofsalesis48,000. Calculate the inventory turnover rate. [2]
Section B: FIFO and AVCO Methods (Questions 9–14) [14 marks]
9. The following transactions occurred for Lucky Traders in March:
| Date | Details | Units | Unit Cost ($) |
|---|---|---|---|
| 1 Mar | Opening inventory | 100 | 10 |
| 5 Mar | Purchase | 200 | 12 |
| 15 Mar | Sale | 250 | — |
| 20 Mar | Purchase | 100 | 14 |
Using the FIFO method, calculate the value of closing inventory. [3]
10. Using the same data in Question 9, calculate the cost of goods sold under FIFO. [2]
11. Using the AVCO (weighted average cost) method for the same data in Question 9, calculate the issue price per unit after the 5 March purchase (before the sale). [2]
12. Based on your AVCO calculation, calculate the closing inventory value under AVCO. [2]
13. Explain one difference between FIFO and AVCO in periods of rising prices. [2]
14. State which method (FIFO or AVCO) would show a higher closing inventory value during inflation. Give a reason. [3]
Section C: Analysis, Errors and Interpretation (Questions 15–20) [10 marks]
15. Cool Bakers had opening inventory 2,000,closinginventory3,000, and cost of sales $25,000. Calculate inventory turnover rate. [2]
16. Compare the inventory turnover of Cool Bakers (from Q15) with Tasty Bakers whose turnover is 10 times. Comment on efficiency. [2]
17. A student calculated closing inventory as 7,500butthecorrectfigurewas6,000 (overstated). State the effect of this error on the reported profit. [1]
18. List two items that should be included in the cost of inventory. [2]
19. The following bar chart shows closing inventory values under FIFO and AVCO for three companies.
Image pending generation: chart for Q19.
Using the chart, state which company shows AVCO higher than FIFO and explain a possible reason. [2]
20. Explain why choosing an inventory costing method affects the comparison of profit between businesses. [1]
Answers
TuitionGoWhere Practice Paper — Principles of Accounts Secondary 4 (Version 4) Answer Key
Total Marks: 40
Topic: Inventory Costing
Section A: Basic Concepts and Calculations
1. [1 mark]
Answer: Lower of cost and net realisable value (NRV).
Teaching note: Prudence concept requires assets not to be overstated. Inventory is valued at the lower of what it cost and what it can be sold for (NRV).
2. [2 marks]
Answer: Net realisable value is the estimated selling price of inventory minus any costs expected to be incurred in selling and completing the goods.
Marking: 1 mark for selling price minus costs; 1 mark for clear wording.
Common mistake: Confusing NRV with cost price.
3. [2 marks]
COGS = Opening Inventory + Purchases − Closing Inventory
= 4,000+26,000 − 5,000=25,000
Teaching note: Cost of sales links inventory used in the period. Method marks for formula.
4. [2 marks]
Purchases = COGS + Closing Inventory − Opening Inventory
= 30,000+4,800 − 3,200=31,600
Teaching note: Rearranged from COGS formula.
5. [1 mark]
Answer: It would overstate assets and profit, violating prudence / mislead users.
(Any one valid reason.)
6. [1 mark]
Answer: 700(lowerofcost900 and NRV $700).
7. [2 marks]
Answer: Inventory is expected to be sold or used within one year (operating cycle) to generate cash, so it is a current asset.
Marking: 1 mark for within 12 months / operating cycle; 1 mark for conversion to cash/sale.
8. [2 marks]
Inventory Turnover = COGS ÷ Average Inventory = 48,000÷6,000 = 8 times.
Teaching note: Average inventory given; shows how many times stock is sold per year.
Section B: FIFO and AVCO Methods
9. [3 marks]
FIFO: Remaining after sale of 250 (100@10 + 150@12) → left: 50@12 + 100@14
Closing inventory = (50 × 12)+(100×14) = 600+1,400 = $2,000
Marking: 1 mark layers, 2 marks calculation.
10. [2 marks]
COGS FIFO = 100×10+150×12 = 1,000+1,800 = 2,800(Ortotalcost4,600 − closing 2,000=2,800)
11. [2 marks]
After 5 Mar: Total cost = 1,000+2,400 = 3,400;Units=300AVCO=3,400 ÷ 300 = $11.33 per unit
Marking: 1 mark total, 1 mark division.
12. [2 marks]
After sale 250: 50 units @ 11.33=566.50
Add 100@14=1,400 → Closing = 1,966.50(approx1,967)
Teaching note: Weighted average recalculated only at purchase points; sale uses existing average.
13. [2 marks]
In rising prices, FIFO gives lower COGS and higher profit/closing inventory; AVCO smooths cost.
(Any one clear difference.)
14. [3 marks]
FIFO shows higher closing inventory during inflation. Reason: oldest (cheaper) costs are used in COGS, leaving recent (higher) costs in inventory.
Marking: 1 mark method, 2 marks reason.
Section C: Analysis, Errors and Interpretation
15. [2 marks]
Avg Inv = (2,000+3,000) ÷ 2 = 2,500Turnover=25,000 ÷ $2,500 = 10 times.
16. [2 marks]
Cool Bakers = 10 times, Tasty = 10 times → equal efficiency.
Comment: Both sell stock at same rate; no efficiency gap.
(If student notes same, full marks.)
17. [1 mark]
Profit overstated by $1,500 (overstated closing inv → lower COGS → higher profit).
18. [2 marks]
Any two: purchase price, carriage inwards, import duties, direct handling cost.
(1 mark each.)
19. [2 marks]
Company C shows AVCO (3,300)>FIFO(3,100). Reason: possibly falling prices (recent cheaper costs in AVCO layer).
Marking: 1 mark identify C, 1 mark reason.
20. [1 mark]
Different methods give different COGS/profit, so comparisons without same method are misleading.
