Answer Key and Marking Scheme – Version 5

Total Marks: 60

Section A: Inventory Costing and Valuation (15 marks)

Question 1: Inventory Turnover Rate (5 marks)

(a) Calculate the inventory turnover rate for Sunrise Trading. (2 marks)

Answer: Average inventory = (Opening inventory + Closing inventory) ÷ 2 = ( $18,000 +$ 22,000) ÷ 2 = $20,000

Inventory turnover rate = Cost of goods sold ÷ Average inventory = $160,000 ÷$ 20,000 = 8 times

Marking:

1 mark for correct calculation of average inventory
1 mark for correct inventory turnover rate (8 times)

(b) Explain what the inventory turnover rate indicates about a business's efficiency in managing its inventory. (2 marks)

Answer: The inventory turnover rate indicates how many times a business sells and replaces its inventory during a period. A higher turnover rate generally suggests that the business is efficient in managing its inventory, as it holds inventory for a shorter period. This reduces storage costs, lowers the risk of obsolescence, and improves cash flow. A lower turnover rate may indicate slow-moving inventory, overstocking, or inefficient purchasing.

Marking:

1 mark for stating that it measures how quickly inventory is sold and replaced
1 mark for linking to efficiency (e.g., lower holding costs, reduced obsolescence risk, improved cash flow)

(c) State one limitation of using the inventory turnover rate to assess a business's performance. (1 mark)

Answer (any one of the following):

The inventory turnover rate does not consider the profitability of individual inventory items.
A high turnover rate could result from holding insufficient inventory, leading to stock-outs and lost sales.
The rate may vary due to seasonal factors and may not reflect year-round performance.
It does not account for differences in product mix or industry norms.

Marking:

1 mark for any valid limitation

Question 2: Inventory Valuation Basis (4 marks)

(a) State the basis on which inventory should be valued in the financial statements. (1 mark)

Answer: Inventory should be valued at the lower of cost and net realisable value (NRV).

Marking:

1 mark for correct statement

(b) Explain the accounting concept that supports this valuation basis. (3 marks)

Answer: The accounting concept is prudence (conservatism). This concept requires that:

Assets should not be overstated in the financial statements.
Losses should be recognised as soon as they are foreseen, while profits should only be recognised when they are realised.
By valuing inventory at the lower of cost and NRV, the business ensures that inventory is not carried at an amount higher than what it expects to recover from its sale. If NRV is lower than cost, the loss is recognised immediately by writing down the inventory value.

Marking:

1 mark for identifying the prudence/conservatism concept
1 mark for explaining that assets should not be overstated
1 mark for explaining that losses are recognised immediately when NRV falls below cost

Question 3: Effect of Inventory Error (6 marks)

(a) State the effect of the closing inventory error on the cost of goods sold and net profit. (2 marks)

Answer: Closing inventory is deducted in the calculation of cost of goods sold.

If closing inventory is overstated by $4,000, cost of goods sold is **understated** by$ 4,000.
An understated cost of goods sold leads to an overstated gross profit and, consequently, an overstated net profit by $4,000.

Marking:

1 mark for stating COGS is understated
1 mark for stating net profit is overstated by $4,000

(b) State the effect of the opening inventory error on the cost of goods sold and net profit. (2 marks)

Answer: Opening inventory is added in the calculation of cost of goods sold.

If opening inventory is understated by $2,000, cost of goods sold is **understated** by$ 2,000.
An understated cost of goods sold leads to an overstated gross profit and, consequently, an overstated net profit by $2,000.

Marking:

1 mark for stating COGS is understated
1 mark for stating net profit is overstated by $2,000

(c) Calculate the net effect of both errors on the net profit. (2 marks)

Answer: Both errors cause net profit to be overstated:

Closing inventory overstated → Net profit overstated by $4,000
Opening inventory understated → Net profit overstated by $2,000
Total net profit overstated by $6,000

Marking:

1 mark for identifying that both errors overstate profit
1 mark for correct total of $6,000 overstated

Section B: Inventory Costing Methods (15 marks)

Question 4: FIFO Method (7 marks)

(a) Using the FIFO method, calculate the cost of goods sold for March 2025. (4 marks)

Answer:

Sale on 15 March (250 units):

200 units from opening inventory @ $5.00 =$ 1,000
50 units from 8 March purchases @ $6.00 =$ 300
COGS for 15 March = $1,300

Sale on 28 March (350 units):

Remaining from 8 March: 250 units @ $6.00 =$ 1,500
100 units from 22 March purchases @ $7.00 =$ 700
COGS for 28 March = $2,200

Total COGS = $1,300 +$ 2,200 = $3,500

Marking:

1 mark for correct allocation of 15 March sale (200 @ $5, 50 @$ 6)
1 mark for correct COGS for 15 March ($1,300)
1 mark for correct allocation of 28 March sale (250 @ $6, 100 @$ 7)
1 mark for correct total COGS ($3,500)

(b) Calculate the value of closing inventory as at 31 March 2025 using FIFO. (2 marks)

Answer: Remaining inventory after all sales:

From 22 March purchases: 400 − 100 = 300 units @ $7.00 =$ 2,100

Closing inventory = $2,100

Marking:

1 mark for identifying remaining units (300)
1 mark for correct valuation ($2,100)

(c) Explain one advantage of using the FIFO method for inventory valuation. (1 mark)

Answer (any one of the following):

FIFO values closing inventory at the most recent purchase prices, which closely reflects current market value.
FIFO is logical and easy to understand, as it assumes the oldest inventory is sold first, which often matches the physical flow of goods.
FIFO is accepted by accounting standards and tax authorities in most jurisdictions.

Marking:

1 mark for any valid advantage

Question 5: Weighted Average Cost Method (8 marks)

(a) Calculate the weighted average cost per unit after the purchase on 8 March 2025. (2 marks)

Answer: After 8 March purchase:

Total units = 200 + 300 = 500 units
Total cost = $1,000 +$ 1,800 = $2,800
Weighted average cost per unit = $2,800 ÷ 500 = **$ 5.60**

Marking:

1 mark for correct total cost and total units
1 mark for correct average cost ($5.60)

(b) Calculate the cost of goods sold for the sale on 15 March 2025 using weighted average cost. (2 marks)

Answer: COGS for 15 March = 250 units × $5.60 = **$ 1,400**

Marking:

1 mark for using correct average cost
1 mark for correct COGS ($1,400)

(c) Calculate the weighted average cost per unit after the purchase on 22 March 2025. (2 marks)

Answer: After 15 March sale, remaining inventory:

Units = 500 − 250 = 250 units
Cost = $2,800 −$ 1,400 = $1,400

After 22 March purchase:

Total units = 250 + 400 = 650 units
Total cost = $1,400 +$ 2,800 = $4,200
Weighted average cost per unit = $4,200 ÷ 650 = **$ 6.46** (rounded to 2 decimal places)

Marking:

1 mark for correct total cost and total units after 22 March
1 mark for correct average cost ($6.46)

(d) Calculate the value of closing inventory as at 31 March 2025 using weighted average cost. (2 marks)

Answer: After 28 March sale (350 units):

Remaining units = 650 − 350 = 300 units
Closing inventory = 300 units × $6.46 = **$ 1,938**

Marking:

1 mark for identifying remaining units (300)
1 mark for correct valuation ($1,938)

Section C: Inventory Analysis and Decision-Making (15 marks)

Question 6: Comparative Inventory Analysis (8 marks)

(a) Calculate the gross profit margin for both businesses. (4 marks)

Answer:

Alpha Trading: Gross profit = Revenue − COGS = $500,000 −$ 350,000 = $150,000 Gross profit margin = ($ 150,000 ÷ $500,000) × 100% = 30%

Beta Trading: Gross profit = Revenue − COGS = $400,000 −$ 260,000 = $140,000 Gross profit margin = ($ 140,000 ÷ $400,000) × 100% = 35%

Marking:

1 mark for correct gross profit for Alpha ($150,000)
1 mark for correct gross profit margin for Alpha (30%)
1 mark for correct gross profit for Beta ($140,000)
1 mark for correct gross profit margin for Beta (35%)

(b) Calculate the inventory turnover rate for both businesses. (4 marks)

Answer:

Alpha Trading: Average inventory = ( $40,000 +$ 50,000) ÷ 2 = $45,000 Inventory turnover rate =$ 350,000 ÷ $45,000 = 7.78 times (or 7.8 times)

Beta Trading: Average inventory = ( $30,000 +$ 50,000) ÷ 2 = $40,000 Inventory turnover rate =$ 260,000 ÷ $40,000 = 6.5 times

Marking:

1 mark for correct average inventory for Alpha ($45,000)
1 mark for correct turnover rate for Alpha (7.78 times)
1 mark for correct average inventory for Beta ($40,000)
1 mark for correct turnover rate for Beta (6.5 times)

Question 7: Scenario-Based Decision-Making (7 marks)

(a) Explain how switching from FIFO to weighted average cost would affect COGS and closing inventory value in a period of rising prices. (3 marks)

Answer: In a period of rising prices:

Under FIFO, the oldest (cheaper) inventory is charged to COGS first, resulting in lower COGS and higher closing inventory value (valued at more recent, higher prices).
Under the weighted average cost method, COGS and closing inventory are valued at an average of all purchase prices, which falls between the oldest and newest prices.
Therefore, switching from FIFO to weighted average cost would result in higher COGS and lower closing inventory value compared to FIFO.

Marking:

1 mark for explaining FIFO's effect (lower COGS, higher closing inventory)
1 mark for explaining weighted average cost's effect (averages prices)
1 mark for concluding that switching increases COGS and decreases closing inventory value

(b) Recommend whether Gamma Enterprise should switch to the weighted average cost method. Provide two justified reasons. (4 marks)

Answer:

Recommendation: Gamma Enterprise should switch to the weighted average cost method. (Accept either recommendation if well-justified.)

Reason 1 (Accounting factor): The weighted average cost method smooths out price fluctuations over time. In a period of rising prices, it provides a more moderate and stable measure of both COGS and inventory value, avoiding the extreme effects of FIFO where older, lower costs are matched against current revenues. This results in a more conservative profit figure.

Reason 2 (Non-accounting factor): The weighted average cost method is simpler to apply when inventory items are homogeneous and interchangeable. It reduces the need to track specific batches of inventory, which can lower administrative costs and reduce the risk of errors in inventory records. This is particularly beneficial if the business deals with large volumes of similar products.

Marking:

1 mark for clear recommendation
1 mark for first justified reason (must include explanation, not just a statement)
1 mark for second justified reason (must include explanation, not just a statement)
1 mark for considering both accounting and non-accounting factors (at least one of each, or a balanced discussion)

Section D: Integrated Inventory and Financial Statements (15 marks)

Question 8: Inventory Adjustments and Profit Effect (7 marks)

(a) Calculate the adjusted closing inventory value as at 31 December 2025. (3 marks)

Answer:

Adjustment 1 – Damaged goods:

Cost of damaged goods = $2,000
NRV = Selling price − Selling costs = $500 −$ 100 = $400
Lower of cost ( $2,000) and NRV ($ 400) = $400
Write-down required = $2,000 −$ 400 = $1,600

Adjustment 2 – Goods received but not included:

Goods costing $1,500 should be included in closing inventory.

Adjusted closing inventory: = $30,000 −$ 1,600 + $1,500 = **$ 29,900**

Marking:

1 mark for correct NRV calculation for damaged goods ($400)
1 mark for correct write-down ($1,600)
1 mark for correct adjusted closing inventory ($29,900)

(b) Prepare the trading portion of the income statement for the year ended 31 December 2025. (4 marks)

Answer:

Delta Trading Trading Portion of the Income Statement for the year ended 31 December 2025

	$	$
Revenue		300,000
Less: Cost of Goods Sold
Opening inventory	25,000
Add: Purchases	180,000
Less: Purchases returns	(5,000)
Add: Carriage inwards	3,000
	203,000
Less: Closing inventory	(29,900)
Cost of Goods Sold		(173,100)
Gross Profit		126,900

Marking:

1 mark for correct net purchases ($175,000) and inclusion of carriage inwards
1 mark for correct cost of goods available for sale ($203,000)
1 mark for correct adjusted closing inventory ($29,900)
1 mark for correct gross profit ($126,900)

Question 9: Comprehensive Inventory Problem (8 marks)

(a) Calculate the cost of goods sold for January 2025 using FIFO. (4 marks)

Answer:

Sale on 10 January (300 units):

300 units from 2 January purchases @ $8.00 =$ 2,400

Sale on 25 January (450 units):

Remaining from 2 January: 200 units @ $8.00 =$ 1,600
250 units from 18 January purchases @ $10.00 =$ 2,500
COGS for 25 January = $4,100

Total COGS = $2,400 +$ 4,100 = $6,500

Marking:

1 mark for correct allocation of 10 January sale (300 @ $8)
1 mark for correct COGS for 10 January ($2,400)
1 mark for correct allocation of 25 January sale (200 @ $8, 250 @$ 10)
1 mark for correct total COGS ($6,500)

(b) Calculate the gross profit for January 2025. (2 marks)

Answer:

Total revenue:

10 January: 300 units × $15 =$ 4,500
25 January: 450 units × $16 =$ 7,200
Total revenue = $11,700

Gross profit = Revenue − COGS = $11,700 −$ 6,500 = $5,200

Marking:

1 mark for correct total revenue ($11,700)
1 mark for correct gross profit ($5,200)

(c) Calculate the value of closing inventory as at 31 January 2025. (2 marks)

Answer:

Remaining inventory after all sales:

From 18 January purchases: 400 − 250 = 150 units @ $10.00 =$ 1,500
From 30 January purchases: 200 units @ $11.00 =$ 2,200

Closing inventory = $1,500 +$ 2,200 = $3,700

Marking:

1 mark for identifying remaining units (150 from 18 Jan, 200 from 30 Jan)
1 mark for correct valuation ($3,700)
