TuitionGoWhere Practice Paper — Principles of Accounts Secondary 4 (Version 3) Answer Key

Topic: Inventory Costing
Total Marks: 60

---

Section A: Basic Concepts and Simple Calculations

1. [1 mark] Answer: Lower of cost and net realisable value (NRV). Teaching note: Inventory must not be overstated. The prudence concept says we should not anticipate profits but provide for losses, so we take the lower of what it cost us or what we can sell it for (NRV).

2. [2 marks]

• Opening inventory: $4,000
• • Purchases: $26,000
• − Closing inventory: $5,000
• COGS = 4,000 + 26,000 − 5,000 = $25,000 Marking: 1 mark for formula, 1 mark for correct answer.

3. [1 mark] Answer: Profit is overstated by $800. Teaching note: Closing inventory is deducted in COGS. If closing inv is overstated, COGS is understated, so profit is overstated.

4. [2 marks] Answer: Net realisable value is the estimated selling price of inventory minus any costs expected to be incurred in selling and completing it (e.g. transport, packaging). Marking: 1 mark selling price, 1 mark less costs to sell.

5. [1 mark] Answer: To avoid overstocking (reduce storage cost / obsolescence) OR to maintain liquidity / meet customer demand. Any one valid reason accepted.

Section B: FIFO and AVCO Methods

6. [3 marks] Receipts: 100 @ $10, then 200 @$12. Total 300 units. Issues: 60 + 150 = 210 units. Closing = 90 units. FIFO: earliest 100 @ $10 issued first, so remaining from 15 Mar batch: 90 units @$12 = $1,080. Marking: 1 for units logic, 2 for value.

7. [2 marks] COGS FIFO = 60 @ $10 + 150 @$10 (from first batch 40 left) + 110 @ $12? Wait: 100@10 issued 60, left 40@10; then 150 issued: 40@10 + 110@12. COGS = (60×10)+(40×10)+(110×12)=600+400+1,320=$2,320. Marking: 1 working, 1 answer.

8. [3 marks] After 15 Mar: total cost = (100×10)+(200×12)=1,000+2,400=$3,400; units=300; AVCO=$3,400/300=$11.333/unit. Issues 210 units ×$11.333 = $2,380; closing 90 ×$11.333 = $1,020. Marking: 1 avg cost, 1 closing calc, 1 answer.

9. [2 marks] FIFO assigns the cost of the oldest items to issues; AVCO assigns a recalculated weighted average after each receipt to all units.

10. [2 marks] FIFO gives higher closing inventory. In rising prices, older (lower) costs go to COGS, leaving newer (higher) costs in closing inventory.

11. [3 marks] 1 Apr: 50@20 = $1,000. 8 Apr issue 30 → 20@20 left. 12 Apr: +100@22 =$2,200; total 120 units, $3,200; AVCO =$3,200/120 = $26.667. 20 Apr issue 80 → closing 40 units ×$26.667 = $1,066.67 ≈$1,067. Marking: 1 avg, 1 units, 1 value.

12. [2 marks] Error: error of omission (omitted receipt). Correct approach: include all receipts before computing FIFO layers; closing should use 15 Mar batch.

---

Section C: Inventory Turnover and Analysis

13. [2 marks] Avg inv = (18,000+22,000)/2 = $20,000. Turnover = 120,000 / 20,000 = 6.0 times. Marking: 1 avg, 1 ratio.

14. [3 marks] Moonlight 6.0 vs Sunrise 6.0 — equal; both similar efficiency. (If different, state higher = faster movement.) Here same, so similar stock management. Marking: 1 compare, 2 comment.

15. [4 marks] Two reasons: (1) Just-in-time purchasing reduces stock held; (2) High-demand fast-moving goods turn over quickly; (3) Efficient inventory system. Any two × 2 marks.

16. [2 marks] Holding period = 365 / 6.0 = 60.8 days ≈ 61 days.

Section D: Integrated and Applied

17. [3 marks] COGS = 6,000+40,000+1,000−7,000 = $40,000. GP = 70,000−40,000 =$30,000. Marking: 1 COGS, 2 GP.

18. [4 marks] FIFO profit = 90,000−50,000=$40,000; AVCO profit=90,000−52,000=$38,000. FIFO higher by $2,000 because lower COGS. In inflation, FIFO uses older lower costs.

19. [3 marks] Net purchases = 80,000−2,000=$78,000. COGS = 10,000+78,000−12,000 =$76,000.

20. [4 marks] GP = 25% × 100,000 = $25,000. COGS = 100,000−25,000 =$75,000. 75,000 = 15,000+70,000−Closing → Closing = 85,000−75,000 = $10,000. Marking: 1 GP, 1 COGS, 2 closing.
