Use the lower of cost and net realisable value basis where required.
Calculators may be used.

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 $4,000, purchases of$ 26,000, and closing inventory of $5,000. Calculate the cost of sales. [2]

4. A business had opening inventory $3,200, closing inventory$ 4,800, 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 $900 have a net realisable value of$ 700. State the value at which they should be reported in the Statement of Financial Position. [1]

8. A shop's average inventory is $6,000 and cost of sales is$ 48,000. 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]

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 $2,000, closing inventory$ 3,000, 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 $7,500 but the correct figure was$ 6,000 (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.

Chart for Q19 (SEC4 Poa)

Generated 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]

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: $700 (lower of cost$ 900 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 = $2,800 (Or total cost$ 4,600 − closing $2,000 =$ 2,800)

11. [2 marks]
After 5 Mar: Total cost = $1,000 +$ 2,400 = $3,400; Units = 300 AVCO =$ 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 = $1,966.50 (approx$ 1,967)
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 = $2,500 Turnover =$ 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.
