TuitionGoWhere Practice Paper — Principles of Accounts O-Level (Version 5) Answer Key

Subject: Principles of Accounts
Level: O-Level
Paper: Practice Paper (AI-Inferred)
Total Marks: 40

Section A: Inventory Costing Fundamentals

1. (1 mark)
Answer: Prudence concept (or lower of cost and net realisable value rule under prudence).
Teaching note: Inventory must not be overstated. Prudence means recognizing losses early; we value stock at lower of cost or NRV.
Marking: 1 mark for correct concept name.

2. (2 marks)
Cost of sales = Opening + Purchases − Closing
= $3,200 +$ 8,500 − $2,900 =$ 8,800
Teaching note: This is the basic inventory equation. Always use cost, not selling price.
Marking: 1 mark for formula, 1 mark for correct answer.

3. (2 marks)
Units available: 200 + 300 = 500. Sold 350 → closing 150 units.
FIFO: earliest remaining are from 5 Jun purchase (300 − 350 + 200 = 150 from $6 batch). 150 ×$ 6 = $900
Teaching note: FIFO assumes first bought are first sold, so closing comes from latest buys.
Marking: 1 mark for units, 1 mark for value.

4. (2 marks)
AVCO smooths price fluctuations and avoids profit manipulation from specific cost layers; gives stable cost per unit.
Teaching note: In rising prices FIFO shows lower COGS and higher profit; AVCO averages so profit is moderate.
Marking: 2 marks for valid reason linked to averaging/stable reporting.

5. (3 marks)
Usable: 120× $10 =$ 1,200; 80× $12 =$ 960. Damaged excluded.
Total = $2,160
Teaching note: Damaged goods not realizable are excluded from inventory.
Marking: 1 mark each line, 1 for total.

Section B: FIFO and AVCO Applications

6. (6 marks)
(a) FIFO:
Available: 100@8, 250@9, 150@10. Sold 350 (200+150).
First 200 from 100@8 + 100@9; next 150 from remaining 150@9.
Closing = 150@10 = $1,500. (3 marks) (b) AVCO: Total cost = 100×8 + 250×9 + 150×10 = 800+2250+1500 =$ 4,550.
Total units = 500. Avg = $9.10. Closing 150 ×$ 9.10 = $1,365. (3 marks)

7. (2 marks)
COGS FIFO = Total cost − closing = $4,550 −$ 1,500 = $3,050.
Marking: 1 formula, 1 answer.

8. (3 marks)
(a) Total cost = 400×4 + 600×5 = 1600+3000 = 4600. Units 1000. Avg = $4.60. (2 marks) (b) Closing = 300 ×$ 4.60 = $1,380. (1 mark)

9. (2 marks)
Rising prices: FIFO gives lower COGS, higher profit, higher closing inventory value; AVCO gives middle. Choice affects tax and profit appearance.
Marking: 2 marks for clear contrast.

Section C: Analysis and Interpretation

10. (4 marks)
(a) 2023: 360,000/90,000 = 4.0 times; 2024: 420,000/105,000 = 4.0 times. (2 marks)
(b) Days = 365/4.0 = 91.25 days. (2 marks)

11. (4 marks)
Trend: turnover stable at 4.0; days 91.25 (slow). Actions: (1) review slow movers, (2) adopt JIT ordering.
Marking: 2 for comment, 1 each action.

12. (4 marks)
Error: inventory is not at selling price. Correct: lower of cost and NRV (prudence).
Marking: 1 error, 3 for correct rule + concept.
