  6. If a business has a very high "days sales in inventory" figure, what does this indicate about its inventory management? [2] \


  7. List two factors that might cause the Net Realizable Value (NRV) of inventory to be lower than its cost. [2] \

Answer Key - O-Level Principles of Accounts Quiz (Inventory Costing)

  1. Definition: The total direct cost of the goods sold by a business during a specific accounting period. (1m)
  2. Calculation: 4,200+4,200 + 15,800 - 3,100=3,100 = **16,900** (1m)
  3. Calculation: (2,000+2,000 + 3,000) / 2 = $2,500 (1m)
  4. Calculation: 45,000/45,000 / 5,000 = 9 times (1m)
  5. Calculation: 22,00022,000 - 14,500 = $7,500 (1m)
  6. FIFO: 12 units sold (10 @ 5,2@5, 2 @ 7). Remaining: 8 units @ 7=7 = **56** (2m)
  7. AVCO: Avg cost = (50+50 + 70) / 20 = 6perunit.Remaining:8units@6 per unit. Remaining: 8 units @ 6 = $48 (2m)
  8. Effect: Gross profit is overstated (Closing inventory \uparrow \rightarrow Cost of Sales \downarrow \rightarrow Gross Profit \uparrow). (1m)
  9. Explanation: Inventory should be recorded at whichever is lower: the original purchase cost or the estimated selling price minus costs to complete/sell. (2m)
  10. Concept: Prudence Concept. (1m) It ensures assets and profits are not overstated and potential losses are recognized. (1m)
  11. Distinction: FIFO assumes the first goods purchased are the first sold; AVCO assigns a weighted average cost to all units. (2m)
  12. Calculation:
    • Turnover Ratio = 120,000/120,000 / 15,000 = 8
    • Days = 365 / 8 = 45.63 days (2m)
  13. Comparison: FIFO results in a higher ending inventory value (more recent, higher prices), thus overstating assets compared to AVCO. (2m)
  14. Indication: Slow-moving inventory or overstocking; inefficient inventory management. (2m)
  15. Factors: Physical damage, obsolescence (outdated style/tech), or a drop in market demand. (2m)
  16. Calculation: 8,000+8,000 + 60,000 - 12,000=12,000 = **56,000** (2m)
  17. Calculation: 95,00095,000 - 56,000 = $39,000 (2m)
  18. Calculation:
    • Avg Inventory = (8,000+8,000 + 12,000) / 2 = $10,000 (1m)
    • Turnover Ratio = 56,000/56,000 / 10,000 = 5.6 (1m)
    • Days = 365 / 5.6 = 65.18 days (1m)
  19. T-Account:
    • Debit side: Balance b/d 5,000;Purchases5,000; Purchases 12,000.
    • Credit side: Cost of Sales 10,500;Balancec/d10,500; Balance c/d 6,500.
    • Balance b/d (Apr 1): $6,500 on Debit side. (4m)
  20. Recommendations:
    • Action 1: Implement a clearance sale to reduce slow-moving stock. (1m) Justification: Converts inventory into cash, increasing the current asset (cash) and reducing inventory, improving the quick ratio. (1m)
    • Action 2: Adopt Just-in-Time (JIT) ordering. (1m) Justification: Reduces the amount of capital tied up in inventory, lowering storage costs and improving overall liquidity. (1m)
