Principles of Accounts Secondary 4 — Inventory Costing (Version 1)

Total Marks: 60

Section A Answers (20 marks)

1. [2 marks]
Cost of Sales = Opening Inv + Purchases + Carriage Inwards − Closing Inv
= $4,000 +$ 30,000 + $1,000 −$ 6,000 = $29,000
Teaching note: Carriage inwards is a cost of getting goods; include it. Common mistake: omit carriage or subtract purchases returns (none here).

2. [2 marks]
Average Inventory = (Opening + Closing) ÷ 2 = ( $8,000 +$ 12,000) ÷ 2 = $10,000
Teaching note: Use average, not just closing.

3. [2 marks]
Inventory Turnover = COGS ÷ Avg Inv = $50,000 ÷$ 10,000 = 5 times
Teaching note: "Times" not "days".

4. [2 marks]
Lower of cost and net realisable value (NRV).
Teaching note: Prudence prevents overstatement of assets.

5. [2 marks]
Profit is overstated by $2,000 (since COGS understated).
Teaching note: Closing inv ↑ → COGS ↓ → Profit ↑.

6. [2 marks]
FIFO: issue oldest first: 100 @ $5 =$ 500; 150 @ $6 =$ 900; total = $1,400
Teaching note: 250 = 100+150.

7. [2 marks]
Total cost = (100× $5)+(200×$ 6) = $500+$ 1,200 = $1,700; total units = 300; AVCO =$ 1,700 ÷ 300 = $5.67 per unit
Teaching note: Weighted average before issue.

8. [2 marks]
COGS = Turnover × Avg Inv = 8 × $5,000 = **$ 40,000**

9. [2 marks]
One reason: lower holding costs / less obsolescence risk / better cash flow. (any 1)
Marking: 2 marks for clear reason.

10. [2 marks]
Higher under FIFO during inflation.
Teaching note: Older cheaper costs in COGS, newer higher cost in closing.

Section B Answers (18 marks)

11. [3 marks]
(a) COGS = $5,000 +$ 40,000 + $2,000 −$ 7,000 = $40,000 [2]
(b) Carriage inwards is a cost to bring goods to saleable condition, so part of inventory cost. [1]

12. [3 marks]
A Co turns over twice as fast (10 vs 5). [1] A is more efficient in stock movement, lower storage cost, less obsolescence. [1] But B may hold more for safety or bulk buying. [1]

13. [3 marks]
Value at NRV $800. [1] Concept: lower of cost and NRV / prudence. [2] Damaged goods cannot sell at cost, so use lower NRV.

14. [3 marks]
FIFO: issue 500 @ $10 + 100 @$ 12 = 600 units; remaining 200 @ $12 = **$ 2,400** [3]

15. [3 marks]
AVCO before issue = ( $5,000+$ 3,600)/800 = $10.75; issue 600 ×$ 10.75 = $6,450; remaining 200 ×$ 10.75 = $2,150 [3]

16. [3 marks]
COGS understated $3,000 → profit overstated$ 3,000. [2] SFP: inventory overstated $3,000, net assets overstated. [1]

Section C Answers (22 marks)

17. [5 marks]
(a) NRV = estimated selling price − costs to sell. [1]
(b) COGS = $9,000 + ($ 55,000− $2,000) +$ 1,500 − $10,500 = **$ 53,000** [3]
(c) Ignores profitability, size, or industry differences. [1]

18. [5 marks]
(a) GP = 25% × $120,000 =$ 30,000; COGS = $90,000. [2] (b) From inv: COGS =$ 6,000+ $44,000−$ 8,000 = $42,000. Inconsistent; implied closing understated by$ 48,000 or purchases understated. [3]

19. [5 marks]
FIFO: Jul15 iss 200@4+50@5= $1,050; remaining 250@5+100@6=$ 1,850; Jul25 iss 200@5= $1,000; closing 50@5+100@6=$ 850. [3]
AVCO: after Jul10 avg= $4.60; iss250=$ 1,150; rem [email protected]; after Jul20 avg=( $1,150+$ 600)/350= $5.00; iss200=$ 1,000; closing 150@5=$750. [2]

20. [5 marks]
(a) A: 80,000/16,000=5 times; B: 60,000/20,000=3 times. [2]
(b) A more efficient. Reason: better demand forecasting or lean stock. [3]
