Answers
TuitionGoWhere Practice Paper - Principles of Accounts Secondary 4
SA1 Examination - Version 2 - ANSWER KEY
TuitionGoWhere Secondary School (AI)
Section A: Short Answer Questions (10 marks)
Question 1 (2 marks)
Answer:
- Inventory should be valued at the lower of cost and net realisable value (NRV). (1 mark)
- The accounting concept that supports this basis is prudence/conservatism. This concept requires that assets should not be overstated and losses should be recognised as soon as they are foreseen. By valuing inventory at the lower of cost and NRV, the business ensures that inventory is not recorded at an amount higher than what it can recover from its sale. (1 mark)
Marking notes:
- Award 1 mark for stating "lower of cost and NRV" or equivalent.
- Award 1 mark for identifying prudence/conservatism and providing a brief explanation linking it to inventory valuation.
Question 2 (2 marks)
Answer:
- Cash sale: The customer pays at the point of purchase. The business receives immediate cash.
- Journal entry: Dr. Cash / Cr. Revenue (½ mark)
- Credit sale: The customer pays at a later date. The business records a receivable.
- Journal entry: Dr. Trade Receivables / Cr. Revenue (½ mark)
- The key difference is the timing of cash receipt: immediate for cash sales, deferred for credit sales. (1 mark)
Marking notes:
- Award ½ mark for each correct journal entry.
- Award 1 mark for clearly explaining the timing difference.
Question 3 (2 marks)
Answer (any two of the following, 1 mark each):
- Insufficient funds in the drawer's bank account.
- Signature mismatch or missing signature on the cheque.
- The cheque is post-dated.
- The cheque is stale (presented after its validity period, typically 6 months).
- There are unauthorised alterations on the cheque.
- The drawer's account has been closed.
Marking notes:
- Award 1 mark for each valid reason, up to a maximum of 2 marks.
Question 4 (2 marks)
Answer:
- Closing inventory is part of the cost of sales calculation: Cost of Sales = Opening Inventory + Purchases − Closing Inventory.
- If closing inventory is overstated, cost of sales will be understated (because a larger amount is subtracted). (1 mark)
- Since Gross Profit = Revenue − Cost of Sales, an understated cost of sales results in gross profit being overstated by $2,500. (1 mark)
Marking notes:
- Award 1 mark for identifying that gross profit is overstated.
- Award 1 mark for stating the amount ($2,500) or explaining the logic clearly.
Question 5 (2 marks)
Answer:
- Net realisable value (NRV) is the estimated selling price of inventory in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale. (2 marks)
Marking notes:
- Award 2 marks for a complete definition including both elements (selling price minus costs to sell).
- Award 1 mark for a partial definition (e.g., only mentioning selling price).

- Award 1 mark for correct final answer ($139,100).
(b) Explanation (2 marks)

Marking notes:
- Award 1 mark for identifying carriage inwards as a direct cost of purchases.
- Award 1 mark for explaining that it is necessary to bring inventory to saleable condition/location.

- Award 1 mark for correct answer (40.19%).
(c) Commentary (2 marks)
Westwood Enterprise's gross profit margin of 40.19% is higher than the industry average of 38%.

Marking notes:
- Award 1 mark for stating that the margin is higher than the industry average.
- Award 1 mark for providing a reasonable interpretation (e.g., better cost control, stronger pricing power).
Question 8 (8 marks)
(a) FIFO method - Closing inventory (4 marks)
Total units available = 200 + 300 + 250 = 750 units Total units sold = 350 + 200 = 550 units Closing inventory units = 750 − 550 = 200 units

Closing inventory (FIFO) = $3,400
Marking notes:
- Award 1 mark for correctly calculating closing inventory units (200).
- Award 1 mark for identifying that FIFO uses most recent purchases for closing inventory.
- Award 1 mark for correct unit cost ($17.00).

- Award 1 mark for correct AVCO after second purchase ($16.475).
- Award 1 mark for correct closing inventory units (200).

Question 9 (8 marks)
(a) Inventory turnover rate (4 marks)
2024: Average inventory = (26,000) ÷ 2 = 150,000 ÷ $24,000 = 6.25 times
2025: Average inventory = (30,000) ÷ 2 = 182,000 ÷ $28,000 = 6.50 times
Marking notes:
- Award 1 mark for each correct average inventory calculation (2 marks total).
- Award 1 mark for each correct turnover rate (2 marks total).
(b) Gross profit margin (2 marks)
2024: Gross profit = 150,000 = 100,000 ÷ $250,000) × 100% = 40.00%
2025: Gross profit = 182,000 = 98,000 ÷ $280,000) × 100% = 35.00%
Marking notes:
- Award 1 mark for each correct gross profit margin (1 mark each).
(c) Commentary (2 marks)
The inventory turnover rate increased from 6.25 times to 6.50 times, indicating that inventory is being sold more quickly in 2025. However, the gross profit margin decreased from 40.00% to 35.00%. This suggests that while the business is moving inventory faster, it may be doing so by reducing selling prices or facing higher purchase costs, which has reduced profitability per dollar of sales.
Marking notes:
- Award 1 mark for noting the increase in turnover rate and decrease in gross profit margin.
- Award 1 mark for providing a reasonable interpretation linking the two changes (e.g., faster sales but lower margins, possible price reductions).

Question 11 (10 marks)
(a) Inventory turnover rate (4 marks)
Riverside Enterprise: Average inventory = (42,000) ÷ 2 = 310,000 ÷ $40,000 = 7.75 times
Valley Trading: Average inventory = (36,000) ÷ 2 = 273,000 ÷ $33,000 = 8.27 times

- Award 1 mark for each correct turnover rate (2 marks total).

Riverside Enterprise: Gross profit = 310,000 = 190,000 ÷ $500,000) × 100% = 38.00%
Valley Trading: Gross profit = 273,000 = 147,000 ÷ $420,000) × 100% = 35.00%
Marking notes:
- Award 1 mark for each correct gross profit margin (1 mark each).
(c) Comparison and commentary (4 marks)
Valley Trading has a higher inventory turnover rate (8.27 times) compared to Riverside Enterprise (7.75 times). This means Valley Trading sells its inventory more quickly.
Two possible reasons for the difference:
- Pricing strategy: Valley Trading may be selling its products at lower prices (as evidenced by its lower gross profit margin of 35.00% compared to Riverside's 38.00%), which could attract more customers and lead to faster inventory movement.
- Product mix: Valley Trading may sell products that have higher demand or are more fast-moving, while Riverside Enterprise may carry slower-moving or higher-end products that take longer to sell but generate higher margins.
Marking notes:
- Award 1 mark for correctly identifying which business has the higher turnover rate.
- Award 1 mark for linking the turnover difference to the gross profit margin difference.
- Award 1 mark for each valid reason (2 marks total). Reasons must be plausible and linked to the figures provided.
