Answer Key - Secondary 4 Principles of Accounts Quiz: Inventory Costing

1. Basis of Valuation

  • Lower of cost and net realisable value (NRV). (1m)

2. Accounting Concept

  • Prudence Concept. (1m)
  • Explanation: To ensure assets and profits are not overstated. (1m)

3. Net Realisable Value (NRV)

  • The estimated selling price (1m) minus the estimated costs of completion and sale. (1m)

4. FIFO vs AVCO (Rising Prices)

  • Higher. (1m)

5. AVCO Preference

  • Smoothens the effect of price fluctuations (1m) / provides a more stable average cost for pricing decisions. (1m)

6. Carriage Outwards

  • No / Not included (it is an operating expense, not a cost of purchase). (1m)

7. Cost of Sales Calculation

  • 12,000+(12,000 + (85,000 - 3,000)+3,000) + 1,500 - $15,000 (2m)
  • = $79,500 (1m)

8. Inventory Turnover Rate

  • Average Inventory = (18,000+18,000 + 22,000) / 2 = $20,000 (1m)
  • Turnover = 120,000/120,000 / 20,000 (1m)
  • = 6 times (1m)

9. Average Inventory

  • Average Inventory = Cost of Sales / Turnover Rate (1m)
  • 200,000/5=200,000 / 5 = 40,000 (1m)

10. Closing Inventory

  • Closing Inventory = Opening + Purchases - Cost of Sales (1m)
  • 5,000+5,000 + 40,000 - 32,000=32,000 = 13,000 (1m)

11. NRV Valuation

  • Cost = 50;NRV=50; NRV = 45 - 5=5 = 40 (1m)
  • Lower of cost and NRV = $40 (1m)

12. Gross Profit

  • COGS = 20,000+20,000 + 70,000 - 15,000=15,000 = 75,000 (1m)
  • Gross Profit = 150,000−150,000 - 75,000 (1m)
  • = $75,000 (1m)

13. Cost of Sales

  • COGS = Average Inventory × Turnover Rate (1m)
  • 10,000×8=10,000 × 8 = 80,000 (1m)

14. Cost of Sales

  • 8,000+8,000 + 50,000 - $6,000 (1m)
  • = $52,000 (1m)

15. Overstated Closing Inventory

  • Closing inventory is subtracted from COGS. Overstating it makes COGS lower. (1m)
  • Therefore, profit is overstated by $2,000. (1m)

16. Understated Opening Inventory

  • Opening inventory is added to COGS. Understating it makes COGS lower. (1m)
  • Lower COGS leads to a higher Gross Profit. (2m)

17. Comparison

  • Company A is more efficient. (1m)
  • Reason: A higher turnover rate (12 vs 4) indicates that stock is sold and replaced more quickly. (2m)
  • This reduces holding costs and the risk of obsolescence. (1m)

18. High Turnover / Low Margin

  • The business may be using a "high-volume, low-price" strategy. (2m)
  • Selling goods quickly at a very small markup to attract more customers. (1m)

19. Non-accounting Factors

  • (Any two of the following):
    • Storage capacity/Warehouse space (1m + 1m explanation)
    • Reliability of suppliers/Lead time (1m + 1m explanation)
    • Perishability of goods (1m + 1m explanation)
    • Market trends/Fashion cycles (1m + 1m explanation)

20. FIFO to AVCO (Falling Prices)

  • Under FIFO (falling prices), the oldest (more expensive) stock is sold first, and closing inventory consists of the newest (cheaper) stock. (2m)
  • AVCO averages the costs. In a falling price environment, the average cost will be higher than the most recent cost. (2m)
  • Therefore, closing inventory will likely increase.
