SA1 — Version 2 of 5: Answer Key & Marking Scheme

Section A: Short Answer Questions [10 marks]

1. State two reasons why a business should value inventory at the lower of cost and net realisable value. [2]

Answer:

  • To ensure that current assets are not overstated in the statement of financial position. [1]
  • To ensure that profit is not overstated in the income statement. [1]

Marking notes:

  • Award 1 mark for each valid reason, up to 2 marks.
  • Accept equivalent phrasing such as "to comply with the prudence concept" or "to avoid overstating assets/profit."
  • Do not accept vague answers like "it is the rule" without explanation.

2. Define net realisable value. [2]

Answer: Net realisable value is the estimated selling price of inventory less any costs necessary to make the sale (e.g., repair costs, selling expenses, delivery costs). [2]

Marking notes:

  • Award 2 marks for a complete definition that includes both the selling price element AND the deduction of costs to sell.
  • Award 1 mark if only "estimated selling price" is stated without mentioning costs to deduct.
  • Do not award full marks for definitions that confuse NRV with cost.

3. A business uses the FIFO method of inventory valuation. During a period of rising prices, explain the effect of using FIFO on the value of closing inventory compared to using the weighted average method. [2]

Answer: Under FIFO, the closing inventory is valued at the most recent (higher) purchase prices. [1] Under the weighted average method, closing inventory is valued at an average of all purchase prices, which would be lower than the most recent prices during a period of rising prices. [1] Therefore, FIFO gives a higher closing inventory value than the weighted average method when prices are rising.

Marking notes:

  • Award 1 mark for identifying that FIFO values closing inventory at more recent/higher prices.
  • Award 1 mark for comparing this to weighted average (lower/average value).
  • Accept answers that state FIFO results in a higher closing inventory value with a valid explanation.

4. State one advantage and one disadvantage of using the weighted average method of inventory valuation. [2]

Answer:

  • Advantage: It smooths out price fluctuations, so the cost of sales and closing inventory are not significantly affected by extreme price changes. [1]
  • Disadvantage: The weighted average cost may not reflect the actual physical flow of goods, and it can be more time-consuming to recalculate after each purchase. [1]

Marking notes:

  • Award 1 mark for a valid advantage and 1 mark for a valid disadvantage.
  • Accept other valid points, e.g., advantage: "reduces the opportunity to manipulate profit by choosing which units to sell"; disadvantage: "does not reflect current replacement cost in the statement of financial position."

5. Explain why a business should not include damaged goods at full cost when valuing inventory. [2]

Answer: Damaged goods may not be able to be sold at their original selling price, so their net realisable value is likely to be lower than cost. [1] Valuing them at full cost would overstate the value of closing inventory and overstate profit, which violates the prudence concept. [1]

Marking notes:

  • Award 1 mark for identifying that damaged goods have a lower NRV.
  • Award 1 mark for linking to the prudence concept or the overstatement of assets/profit.
  • Accept equivalent reasoning.

Section B: Structured / Calculation Questions [30 marks]

6.(a) Prepare an inventory record card using the FIFO method. [5]

Answer:

Inventory Record Card — FIFO Method

DateReceiptsIssuesBalance
Units$/unit$Units$/unit$Units$/unit$
Mar 18012.00960
Mar 812013.001,5608012.00960

10014.001,400
Mar 285013.006508014.001,120
2014.00280

Closing inventory at 31 March 2025 = 80 units × 14.00=14.00 = 1,120 [shown above]

Marking notes:

  • Award 1 mark for correctly issuing 80 units at $12.00 first on Mar 15.
  • Award 1 mark for correctly issuing the remaining 70 units at $13.00 on Mar 15.
  • Award 1 mark for correctly recording the Mar 22 purchase.
  • Award 1 mark for correctly issuing 50 units at 13.00and20unitsat13.00 and 20 units at 14.00 on Mar 28.
  • Award 1 mark for the correct closing inventory value of $1,120.
  • Award method marks even if arithmetic errors are made, provided the FIFO logic is correct.

6.(b) Calculate the cost of sales for the month of March 2025. [2]

Answer:

Total goods available for sale = (80 × 12.00)+(120×12.00) + (120 × 13.00) + (100 × 14.00)=14.00) = 960 + 1,560+1,560 + 1,400 = $3,920

Cost of sales = Total goods available − Closing inventory = 3,920−3,920 − 1,120 = $2,800

Alternative (from issues): Mar 15 issues: 960+960 + 910 = 1,870Mar28issues:1,870 Mar 28 issues: 650 + 280=280 = 930 Total cost of sales = 1,870+1,870 + 930 = $2,800

Marking notes:

  • Award 2 marks for the correct answer with working.
  • Award 1 mark for correct method with arithmetic error.
  • Accept either method (total available minus closing inventory, or sum of issues).

7.(a) Calculate the cost of sales for the year ended 31 December 2025. [3]

Answer:

Cost of sales = Opening inventory + Net purchases + Carriage inwards − Closing inventory

Net purchases = Purchases − Returns outwards = 178,000−178,000 − 6,000 = $172,000

Cost of sales = 32,000+32,000 + 172,000 + 4,000−4,000 − 28,000 = $180,000

Marking notes:

  • Award 1 mark for correctly calculating net purchases ($172,000).
  • Award 1 mark for correctly including carriage inwards and deducting closing inventory.
  • Award 1 mark for the correct final answer ($180,000).
  • Award method marks if the formula is correct but arithmetic is wrong.

7.(b) Calculate the gross profit for the year ended 31 December 2025. [2]

Answer:

Gross profit = Sales − Cost of sales = 280,000−280,000 − 180,000 = $100,000

Marking notes:

  • Award 2 marks for correct answer with working.
  • Award 1 mark for correct method with arithmetic error.
  • If cost of sales was wrong in (a), carry forward the error and award full marks here if the method is correct.

7.(c) Calculate the gross profit margin (to 1 decimal place). [2]

Answer:

Gross profit margin = (Gross profit ÷ Sales) × 100% = (100,000÷100,000 ÷ 280,000) × 100% = 35.7%

Marking notes:

  • Award 1 mark for correct formula/method.
  • Award 1 mark for correct answer to 1 decimal place.
  • Accept 35.71% if rounded to 2 decimal places, but 1 decimal place is required.

8.(a) Calculate the inventory turnover rate for the year ended 30 June 2025. [3]

Answer:

Average inventory = (Opening inventory + Closing inventory) ÷ 2 = (24,000+24,000 + 32,000) ÷ 2 = $28,000

Inventory turnover rate = Cost of sales ÷ Average inventory = 192,000÷192,000 ÷ 28,000 = 6.9 times (to 1 decimal place)

Marking notes:

  • Award 1 mark for correct average inventory calculation.
  • Award 1 mark for correct formula application.
  • Award 1 mark for correct answer (6.9 times).
  • Common mistake: using only opening inventory (192,000÷192,000 ÷ 24,000 = 8.0) — award 2/3 for correct formula but wrong input.

8.(b) Calculate the average inventory holding period in days (to the nearest day). [2]

Answer:

Average inventory holding period = 365 days ÷ Inventory turnover rate = 365 ÷ 6.9 = 53 days (to the nearest day)

Marking notes:

  • Award 1 mark for correct formula.
  • Award 1 mark for correct answer (53 days).
  • Accept 52.9 days rounded to 53 days.
  • If turnover rate was wrong in (a), carry forward the error.

8.(c) The inventory turnover rate for the previous year was 6.5 times. Comment on the change in inventory management efficiency. [2]

Answer:

The inventory turnover rate has increased from 6.5 times to 6.9 times. [1] This means the business is selling and replacing its inventory more quickly than the previous year, which indicates improved inventory management efficiency. Inventory is not sitting idle for as long, reducing storage costs and the risk of obsolescence. [1]

Marking notes:

  • Award 1 mark for identifying the increase/improvement.
  • Award 1 mark for explaining what this means in terms of efficiency.
  • Accept alternative valid explanations (e.g., faster stock rotation, reduced holding period).

9.(a) Prepare an inventory record card using the weighted average method. [5]

Answer:

Inventory Record Card — Weighted Average Method

DateReceiptsIssuesBalance
Units$/unit$Units$/unit$Units$/unit$
May 15020.001,000
May 108022.001,76013021.232,760

May 256024.001,44010022.892,289
May 304022.899166022.891,373

Working:

After May 10 purchase: Weighted average cost = (1,000+1,000 + 1,760) ÷ (50 + 80) = 2,760÷130=∗∗2,760 ÷ 130 = **21.23** per unit

After May 25 purchase: Weighted average cost = (849+849 + 1,440) ÷ (40 + 60) = 2,289÷100=∗∗2,289 ÷ 100 = **22.89** per unit

Closing inventory at 31 May 2025 = 60 units × 22.89=22.89 = 1,373 (or $1,373.40 unrounded)

Marking notes:

  • Award 1 mark for correct weighted average cost after May 10 ($21.23).
  • Award 1 mark for correct balance after May 18 issues.
  • Award 1 mark for correct weighted average cost after May 25 ($22.89).
  • Award 1 mark for correct issues on May 30.
  • Award 1 mark for correct closing inventory value (1,373or1,373 or 1,373.40).
  • Award method marks for correct approach even if rounding differences occur.

9.(b) Explain one reason why Priya might prefer the weighted average method over FIFO for her clothing boutique. [2]

Answer:

Priya might prefer the weighted average method because clothing prices may fluctuate frequently due to seasonal changes and supplier discounts. [1] The weighted average method smooths out these price fluctuations, giving a more stable and representative cost per unit for pricing decisions and profit measurement. [1]

Marking notes:

  • Award 1 mark for identifying a valid reason (e.g., price smoothing, ease of use, stable cost).
  • Award 1 mark for linking the reason to the context of a clothing boutique.
  • Accept other valid reasons, e.g., "it is simpler to maintain" or "it reduces the impact of choosing which items to sell first."

Section C: Scenario-Based Question [10 marks]

10.(a) Calculate the gross profit using the FIFO method. [3]

Answer:

Cost of sales (FIFO) = Opening inventory + Purchases − Closing inventory (FIFO) = 40,000+40,000 + 260,000 − 50,000=50,000 = 250,000

Gross profit (FIFO) = Sales − Cost of sales = 450,000−450,000 − 250,000 = $200,000

Marking notes:

  • Award 1 mark for correct cost of sales calculation.
  • Award 1 mark for correct gross profit calculation.
  • Award 1 mark for correct final answer ($200,000).

10.(b) Calculate the gross profit using the weighted average method. [3]

Answer:

Cost of sales (WA) = Opening inventory + Purchases − Closing inventory (WA) = 40,000+40,000 + 260,000 − 46,000=46,000 = 254,000

Gross profit (WA) = Sales − Cost of sales = 450,000−450,000 − 254,000 = $196,000

Marking notes:

  • Award 1 mark for correct cost of sales calculation.
  • Award 1 mark for correct gross profit calculation.
  • Award 1 mark for correct final answer ($196,000).

10.(c) Calculate the net profit for the year ended 31 December 2025 under both methods. [2]

Answer:

Net profit = Gross profit − Operating expenses

FIFO method: Net profit = 200,000−200,000 − 120,000 = $80,000 [1]

Weighted average method: Net profit = 196,000−196,000 − 120,000 = $76,000 [1]

Marking notes:

  • Award 1 mark for each correct net profit figure.
  • Carry forward errors from parts (a) and (b) if the method is correct.

10.(d) Advise Amir on whether he should switch to the weighted average method. Give two reasons for your answer. [2]

Answer:

Amir should not switch to the weighted average method. [1 — for the decision with valid reasoning]

Reason 1: Under FIFO, the closing inventory is valued at the most recent purchase prices, which better reflects the current replacement cost of inventory in the statement of financial position. This gives a more realistic view of the business's assets.

Reason 2: Under FIFO, the gross profit (200,000)andnetprofit(200,000) and net profit (80,000) are higher than under weighted average (196,000and196,000 and 76,000 respectively). Switching would reduce reported profit, which may not be desirable for presenting the business's performance to stakeholders such as banks or investors.

Alternative acceptable answer (if student argues FOR switching):

Amir should switch to the weighted average method.

Reason 1: The weighted average method smooths out price fluctuations, giving a more stable cost of sales figure that is not affected by the timing of purchases.

Reason 2: Under weighted average, the lower closing inventory value (46,000vs46,000 vs 50,000) is more conservative and aligns with the prudence concept, avoiding overstatement of assets and profit.

Marking notes:

  • Award 1 mark for a clear decision (either for or against switching is acceptable).
  • Award 1 mark for two valid, well-explained reasons.
  • Accept either position as long as the reasoning is sound and relevant to the scenario.
  • Do not award marks for unsupported opinions.
