This paper is syllabus-first generated content and is not derived from official past-year papers.

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. Calculate the cost of goods sold for the year ended 31 Dec 2025 from the following:
Opening inventory $4,000; Purchases$ 26,000; Carriage inwards $1,200; Closing inventory$ 5,500. [2]

4. A trader's closing inventory was overstated by $800. State the effect on the profit for the year. [1]

5. Given opening inventory $3,000 and closing inventory$ 7,000, calculate the average inventory. [1]

6. Cost of goods sold is $60,000 and average inventory is$ 12,000. Calculate the inventory turnover rate. [2]

7. Explain why FIFO is said to issue the oldest items first. [2]

8. Under AVCO, the total cost of 100 units is $2,500. Calculate the weighted average cost per unit. [2]

Section B: FIFO and AVCO Methods (Questions 9–14) [14 marks]

9. The following purchases and sales occurred in January 2025 for M/s Bright Store:

Date	Details	Units	Unit Cost ($)
1 Jan	Opening	50	10
5 Jan	Purchase	100	12
12 Jan	Sale	120	—
20 Jan	Purchase	80	14

Using FIFO, calculate the closing inventory value at 31 Jan 2025. [3]

10. Using the same data in Q9, calculate the cost of goods sold under FIFO. [2]

11. Using AVCO (weighted average recalculated only at end of month for simplicity), calculate the closing inventory value for M/s Bright Store at 31 Jan 2025. Total units available = 230, total cost = $2,780. [3]

12. State one advantage of using FIFO during a period of rising prices. [2]

13. A business uses AVCO. Explain how the average cost per unit changes after each purchase. [2]

14. Compare the closing inventory value under FIFO and AVCO from Q9 and Q11. Which is higher and why? [2]

Section C: Analysis and Interpretation (Questions 15–20) [10 marks]

15. Calculate inventory turnover for Year A: COGS $90,000, opening inventory$ 10,000, closing inventory $14,000. [2]

16. For Year B: COGS $90,000, opening inventory$ 16,000, closing inventory $20,000. Calculate inventory turnover and compare with Year A. [2]

17. Explain one reason why a lower inventory turnover may indicate poor inventory management. [2]

18. The following bar chart shows closing inventory values for a company under FIFO and AVCO over 3 years.

Chart for 18 (SEC4 Poa)

Generated chart for 18.

Based on the chart, state the trend of FIFO closing inventory compared to AVCO. [1]

19. Given the data in Q18, explain why FIFO closing inventory is consistently higher than AVCO in an inflationary period. [2]

20. A shopkeeper values inventory at selling price. State the accounting error and the correct basis. [1]

Topic: Inventory Costing
Total Marks: 40

Section A Answers (16 marks)

1. [1 mark]
Answer: Lower of cost and net realisable value (NRV).
Teaching note: Prudence concept requires assets not to be overstated. Inventory is recorded at the lower of what it cost or what it can be sold for (NRV).

2. [2 marks]
Answer: Net realisable value is the estimated selling price of inventory minus any costs needed to make the sale (e.g., packaging, transport).
Marking: 1 mark for selling price less costs; 1 mark for clear definition.
Teaching note: NRV shows the cash the business will actually get from the stock.

3. [2 marks]
Working:
COGS = Opening + Purchases + Carriage inwards − Closing
= 4,000 + 26,000 + 1,200 − 5,500 = $25,700 Answer:$ 25,700.
Common mistake: Subtracting carriage or adding closing wrongly.

4. [1 mark]
Answer: Profit is overstated by $800.
Teaching note: Overstated closing inventory → lower COGS → higher profit.

5. [1 mark]
Average = (3,000 + 7,000) ÷ 2 = $5,000.

6. [2 marks]
Turnover = COGS ÷ Average Inventory = 60,000 ÷ 12,000 = 5 times.
Answer: 5 times.

7. [2 marks]
Answer: FIFO (First-In-First-Out) assumes the first items bought are the first sold, so closing stock is from latest purchases.
Marking: 1 for definition, 1 for link to closing stock.

8. [2 marks]
Average cost = 2,500 ÷ 100 = $25 per unit.

Section B Answers (14 marks)

9. [3 marks]
FIFO:

Sold 120: 50 from opening (10) = 500; 70 from 5 Jan (12) = 840.
Remaining: 30 from 5 Jan (12) = 360; 80 from 20 Jan (14) = 1,120.
Closing = 360 + 1,120 = $1,480.
Marking: 1 for units remaining, 2 for correct valuation.

10. [2 marks]
COGS = 500 + 840 = $1,340.

11. [3 marks]
AVCO: Total cost $2,780 / 230 units =$ 12.087 per unit.
Closing units = 230 − 120 = 110.
Value = 110 × 12.087 = $1,329.57 ≈$ 1,330.
Marking: 1 avg cost, 1 units, 1 value.

12. [2 marks]
Advantage: FIFO matches older lower costs to COGS, showing higher profit and higher closing inventory in balance sheet during inflation.

13. [2 marks]
After each purchase, total cost ÷ total units available gives new average; it blends old and new costs.

14. [2 marks]
FIFO $1,480 > AVCO$ 1,330 because FIFO uses recent higher cost for closing stock.

Section C Answers (10 marks)

15. [2 marks]
Avg inv = (10,000+14,000)/2 = 12,000.
Turnover = 90,000 ÷ 12,000 = 7.5 times.

16. [2 marks]
Avg = (16,000+20,000)/2 = 18,000.
Turnover = 90,000 ÷ 18,000 = 5 times.
Comparison: Year A (7.5) faster than Year B (5).

17. [2 marks]
Lower turnover means stock sits longer → higher storage cost, obsolescence risk, tied-up cash.

18. [1 mark]
FIFO closing inventory is higher than AVCO each year and both rise.

19. [2 marks]
In inflation, recent costs higher; FIFO closing uses recent high cost, AVCO averages down → FIFO higher.

20. [1 mark]
Error: valued at selling price not cost. Correct: lower of cost and NRV.
