Answer Key & Marking Scheme
Version: 1 of 5

Section A: Multiple Choice & Short Concepts [10 Marks]

Question 1
Answer: B (Prudence)
Marking: 1 mark for correct option.
Explanation: The prudence concept ensures assets are not overstated. Valuing inventory at the lower of cost and NRV prevents overstatement of assets and profit.

Question 2
Answer: A (FIFO)
Marking: 1 mark for correct option.
Explanation: In a period of rising prices, the earliest (cheapest) units are sold first, leaving the latest (most expensive) units in closing inventory. Thus, FIFO yields the highest closing inventory value.

Question 3
Answer: Net Realisable Value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale.
Marking:

1 mark for "estimated selling price".
1 mark for "less costs to complete/sell".
Note: Do not accept "market value" without qualification.

Question 4
Answer: Any two of the following:

Purchase price of goods.
Carriage inwards (freight in).
Import duties/taxes.
Costs of conversion (for manufactured goods).
Marking: 1 mark per correct cost, up to 2 marks.

Question 5
Answer: Any two of the following:

Carriage outwards (delivery to customers).
Storage costs (unless necessary for production).
Administrative overheads.
Selling and distribution costs.
Abnormal waste.
Marking: 1 mark per correct exclusion, up to 2 marks.

Question 6
Answer: B (Overstated by $500)
Marking: 1 mark for correct option.
Explanation: Closing Inventory is deducted from Cost of Goods Available for Sale to get Cost of Sales. If Closing Inventory is too high, Cost of Sales is too low. If Cost of Sales is too low, Gross Profit is too high (overstated).

Question 7
Answer: $51,000 **Marking:** 1 mark for correct answer. **Workings:** Opening Inventory ($ 12,000) + Purchases ( $45,000) + Carriage Inwards ($ 2,000) - Closing Inventory ( $8,000) =$ 51,000.
Note: Carriage Outwards is an expense, not part of Cost of Sales.

Section B: Calculations – FIFO and AVCO [18 Marks]

Question 8

(a) FIFO Closing Inventory
Total Units Available: 100 + 200 + 100 = 400 units.
Total Units Sold: 150 + 180 = 330 units.
Closing Units: 400 - 330 = 70 units.

Under FIFO, the closing inventory consists of the most recently purchased units.
The last purchase was Jan 18: 100 units @ $14.00.
We need 70 units. All 70 come from this batch.

Value = 70 units × $14.00 =$ 980.

Marking:

1 mark for identifying closing units (70).
1 mark for identifying correct batch (Jan 18).
1 mark for correct calculation ($980).
3 marks for clear workings showing the flow of goods.
Total: 6 marks.
Answer: $980

(b) AVCO Closing Inventory (Periodic)
Step 1: Calculate Total Cost of Goods Available for Sale

Jan 1: 100 units @ $10.00 =$ 1,000
Jan 5: 200 units @ $12.00 =$ 2,400
Jan 18: 100 units @ $14.00 =$ 1,400
Total Cost: $1,000 +$ 2,400 + $1,400 =$ 4,800
Total Units: 100 + 200 + 100 = 400 units

Step 2: Calculate Weighted Average Unit Cost
Average Cost = Total Cost / Total Units
Average Cost = $4,800 / 400 =$ 12.00 per unit.

Step 3: Calculate Closing Inventory Value
Closing Units = 70 units (as calculated in part a).
Value = 70 units × $12.00 =$ 840.

Marking:

1 mark for Total Cost ($4,800).
1 mark for Total Units (400).
1 mark for Average Unit Cost ($12.00).
1 mark for Closing Units (70).
1 mark for Final Value ($840).
1 mark for presentation/workings.
Total: 6 marks.
Answer: $840

(c) Higher Gross Profit
Answer: FIFO would result in a higher Gross Profit.
Explanation: FIFO has a higher closing inventory value ( $980 vs$ 840). A higher closing inventory reduces the Cost of Sales. A lower Cost of Sales results in a higher Gross Profit.
Marking:

1 mark for identifying FIFO.
1 mark for explanation linking Closing Inventory -> Cost of Sales -> Gross Profit.
Total: 2 marks.

(d) Advantage of AVCO
Answer: Any one of:

Smoothes out price fluctuations, making profit figures more stable.
Simpler to administer if there are many similar items (no need to track specific batches).
Less opportunity for manipulation of profit by selecting specific batches.
Marking: 2 marks for a clear, relevant advantage.

(e) Disadvantage of FIFO
Answer: Any one of:

In times of inflation, it overstates profit (leading to higher tax).
Can be administratively complex if there are many different batches to track.
Closing inventory value may be outdated if prices change rapidly.
Marking: 2 marks for a clear, relevant disadvantage.

Section C: Analysis and Decision Making [12 Marks]

Question 9

(a) Gross Profit Calculation
(i) FIFO:
Sales ( $500,000) - Cost of Sales ($ 300,000) = $200,000
Marking: 1 mark.

(ii) AVCO:
First, determine AVCO Cost of Sales.
Change in Closing Inventory: FIFO ( $40,000) - AVCO ($ 35,000) = $5,000 decrease. Lower closing inventory means Higher Cost of Sales. AVCO Cost of Sales =$ 300,000 + $5,000 =$ 305,000.
Gross Profit = $500,000 -$ 305,000 = $195,000
Marking: 1 mark.

(b) Impact on Statement of Financial Position
(i) Current Assets:
Current Assets will be lower by $5,000 because Closing Inventory (a current asset) is valued at$ 35,000 instead of $40,000.
Marking: 2 marks (1 for direction "lower", 1 for explanation/reference to inventory).

(ii) Capital / Equity:
Capital/Equity will be lower by $5,000. This is because the Net Profit (and thus Retained Earnings) is lower by$ 5,000 due to the higher Cost of Sales and lower Gross Profit.
Marking: 2 marks (1 for direction "lower", 1 for link to profit/retained earnings).

(c) Prudence Concept
Answer:
The concept of prudence requires that assets and profits are not overstated. By choosing AVCO, the closing inventory is valued lower ( $35,000 vs$ 40,000). This results in a lower asset value and lower profit. This aligns with prudence as it ensures the business does not report inflated wealth or income, providing a more cautious view of the financial position.
Marking:

1 mark for definition/reference to not overstating assets/profit.
1 mark for application to the scenario (AVCO gives lower value).
1 mark for conclusion (AVCO is more prudent in this case).
Total: 3 marks.

(d) Operational Reason for FIFO (Perishable Goods)
Answer:
For perishable goods, FIFO ensures that the oldest stock is sold first. This minimizes the risk of goods expiring, spoiling, or becoming obsolete before they are sold. It aligns the physical flow of goods with the accounting flow, reducing waste and write-offs.
Marking:

1 mark for identifying physical flow/oldest stock sold first.
1 mark for linking to spoilage/expiry risk.
1 mark for clarity/relevance to perishable nature.
Total: 3 marks.
