TuitionGoWhere Practice Paper — Principles of Accounts O-Level (Version 2) Answer Key

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

Teaching notes are provided for each question. This is syllabus-first generated content, not official exam-derived.

---

Section A: Inventory Costing Fundamentals (10 marks)

1. [1 mark]
Formula: Opening Inventory + Purchases − Closing Inventory = Cost of Sales.
Teaching note: Under periodic system we do not record each sale at cost; we find cost of sales by deducting closing stock from goods available.*

2. [2 marks]
Goods available = (50 × $8) + (120 ×$10) = $400 +$1,200 = $1,600. Closing inventory (FIFO, 70 units left from$10 batch) = 70 × $10 =$700.
Cost of sales = $1,600 −$700 = $900.
Mark breakdown: 1 for goods available, 1 for COS.

3. [2 marks]
Closing inventory is valued at the lower of cost and net realizable value (NRV). This applies the prudence concept — do not overstate assets or profit.
Mark: 1 for rule, 1 for concept.

4. [2 marks]
From Q2: 70 units remaining from 120 bought at $10. FIFO uses oldest cost first for issues, so leftover is newest =$10. 70 × $10 =$700.

5. [1 mark]
Total cost = (80 × $5) + (40 ×$6) = $400 +$240 = $640. Total units = 120. AVCO =$640 ÷ 120 = $5.33 per unit.

6. [2 marks]
FIFO matches actual physical flow (oldest goods sold first) and during rising prices gives lower cost of sales, hence higher reported profit (acceptable to some owners). Or: FIFO closing inventory closer to current replacement cost.
Any one valid reason with explanation = 2 marks.

---

Section B: FIFO and AVCO Applications (16 marks)

7. [3 marks]
Units available: 100+150+100 = 350. Sold: 180+70 = 250. Closing = 100 units.
FIFO: last bought 100 @ $16 =$1,600.
Mark: 1 units, 2 value.

8. [3 marks]
Total cost = (100×$12)+(150×$14)+(100×$16) =$1,200+$2,100+$1,600 = $4,900. Total units = 350. AVCO =$4,900 ÷ 350 = $14.00. Closing = 100 ×$14 = $1,400.
Mark: 1 avg, 2 closing.

9. [1 mark]
Cost of sales = 250 units × $14 (AVCO) =$3,500. (Under FIFO: 180 from $12/$14 + 70 from $14 =$2,140+$980=$3,120; but Q9 asks AVCO) = $3,500.

10. [2 marks]
Error: used only one purchase price ($14) ignoring opening$12 and later $16 batches; AVCO must weight all units at cost. Also 100 units is wrong closing qty? (Actually closing is 100, but cost must be$14.00 weighted, not selected $14 by chance). Main error = did not compute weighted average of all pools.

11. [3 marks]
FIFO:
1 Jul 200@$9; 5 Jul +100@$11 (300); 12 Jul sell 150 → from $9: 150 left (50@$9, 100@$11); 20 Jul +150@$10 (50@$9,100@$11,150@$10 =300); 25 Jul sell 200 → 50@$9, 100@$11, 50@$10 sold; left = 100@$10 + 50@$11? Wait: after 25 Jun sell 200 from oldest: 50@$9 +100@$11 +50@$10 removed, remaining = 100@$10 + 50@$11 = 150 units. Value = (100×$10)+(50×$11)=$1,000+$550=$1,550.
Mark: 1 trace, 2 value.

12. [2 marks]
FIFO assumes oldest costs issued first so closing inventory reflects recent prices; AVCO spreads all costs evenly. When prices rise, FIFO closing > AVCO closing.

13. [2 marks]
FIFO gives higher net profit in rising prices because cost of sales uses cheaper old costs, leaving higher closing inventory and lower expense.

Section C: Analysis and Interpretation (14 marks)

14. [1 mark]
$300,000 ÷$60,000 = 5.0 times.

15. [2 marks]
365 ÷ 5.0 = 73.00 days.

16. [2 marks]
Turnover = $330,000 ÷$75,000 = 4.4 times. Days = 365 ÷ 4.4 = 82.95 days.

17. [2 marks]
Days increased from 73 to 83, so inventory is slower-moving; less efficient, more cash tied up.

18. [2 marks]

1. Reduce slow-moving stock via promotions. 2) Use just-in-time ordering. (Any two valid)

19. [2 marks]
Overstated closing inventory → cost of sales understated → gross profit overstated → net profit overstated by $2,000.

20. [3 marks]
Rule prevents overstatement of inventory asset and profit if NRV < cost (prudence). Users (owners, creditors) get reliable view; avoids misleading decisions.
Mark: 1 rule, 2 user protection.
