Level: O-Level
Paper: Practice Paper 2 (Version 2 of 5)
Total Marks: 50

Section A: Inventory Costing Calculations [20 marks]

Question 1

(a) FIFO Method - Closing Inventory Valuation [4 marks]

Workings:

  1. Calculate total units available and units sold:

    • Opening inventory: 200 units
    • Purchases: 300 + 150 + 200 = 650 units
    • Total units available: 200 + 650 = 850 units
    • Units sold: 250 + 180 = 430 units
    • Closing inventory units: 850 - 430 = 420 units

  2. Apply FIFO (First-In-First-Out) - oldest costs assigned to cost of sales, newest costs remain in closing inventory:

    Units sold (430) taken from:

    • 200 units from opening inventory @ 12.00=12.00 = 2,400
    • 230 units from Jan 5 purchase @ 13.50=13.50 = 3,105
    • Total cost of sales = $5,505

    Closing inventory (420 units) consists of the most recent purchases:

    • Remaining from Jan 5 purchase: 300 - 230 = 70 units @ 13.50=13.50 = 945
    • Jan 18 purchase: 150 units @ 14.00=14.00 = 2,100
    • Jan 28 purchase: 200 units @ 14.50=14.50 = 2,900
    • Total closing inventory = 945+945 + 2,100 + 2,900=2,900 = 5,945

Answer: $5,945 [4]

Marking notes: 1 mark for correct closing inventory units (420), 1 mark for correct identification of cost layers, 2 marks for correct calculation and final answer. Common error: using wrong cost layers or incorrect units sold.

(b) AVCO (Weighted Average) Method - Closing Inventory Valuation [4 marks]

Workings:

  1. Calculate weighted average cost per unit:

    • Total cost of goods available for sale:
      • Opening: 200 × 12.00=12.00 = 2,400
      • Jan 5: 300 × 13.50=13.50 = 4,050
      • Jan 18: 150 × 14.00=14.00 = 2,100
      • Jan 28: 200 × 14.50=14.50 = 2,900
      • Total cost = $11,450
    • Total units available = 850 units
    • Weighted average cost per unit = 11,450÷850=11,450 ÷ 850 = 13.470588... ≈ $13.47 (to 2 decimal places)

  2. Calculate closing inventory value:

    • Closing inventory units = 420 units
    • Closing inventory value = 420 × 13.47=13.47 = 5,657.40

Answer: $5,657.40 [4]

Marking notes: 1 mark for total cost (11,450),1markfortotalunits(850),1markforcorrectaveragecostperunit(11,450), 1 mark for total units (850), 1 mark for correct average cost per unit (13.47), 1 mark for final closing inventory value. Common error: rounding average cost too early or using wrong number of decimal places.

  • Mar 20 Issue (400 units): FIFO takes remaining 200 units @ 8.50+200units@8.50 + 200 units @ 9.00 (Mar 15 purchase)

[5 marks - 1 mark for each correct issue line (2 marks), 1 mark for each correct balance layer after each transaction (3 marks)]

(b) Closing Inventory Value on 31 March 2024 [1 mark]

From the balance column after Mar 25:

  • 100 units @ 9.00=9.00 = 900
  • 200 units @ 9.50=9.50 = 1,900
  • Total = $2,800

Answer: $2,800 [1]

Question 3

(a) Cost of Sales using AVCO (Periodic System) [4 marks]

Workings:

  1. Calculate weighted average cost per unit:

    • Opening inventory: 1,200 × 25.00=25.00 = 30,000
    • Purchase 1: 2,000 × 26.00=26.00 = 52,000
    • Purchase 2: 1,500 × 27.50=27.50 = 41,250
    • Purchase 3: 1,000 × 28.00=28.00 = 28,000
    • Total cost = $151,250
    • Total units = 1,200 + 2,000 + 1,500 + 1,000 = 5,700 units
    • Average cost per unit = 151,250÷5,700=151,250 ÷ 5,700 = 26.535087... ≈ $26.54 (to 2 decimal places)

  2. Calculate cost of sales:

    • Units sold = Total units available - Closing inventory
    • Units sold = 5,700 - 1,800 = 3,900 units
    • Cost of sales = 3,900 × 26.54=26.54 = 103,506

Answer: $103,506 [4]

Marking notes: 1 mark for total cost (151,250),1markfortotalunits(5,700),1markforcorrectaveragecost(151,250), 1 mark for total units (5,700), 1 mark for correct average cost (26.54), 1 mark for correct cost of sales. Common error: using closing inventory units instead of units sold.

(b) Gross Profit [2 marks]

Workings:

  • Sales revenue = $250,000
  • Cost of sales = $103,506
  • Gross profit = 250,000−250,000 - 103,506 = $146,494

Answer: $146,494 [2]

Marking notes: 1 mark for correct formula, 1 mark for correct calculation using cost of sales from (a). Follow-through allowed if (a) is incorrect but method is correct.

(c) Inventory Turnover Ratio [2 marks]

Workings:

  • Average inventory = (Opening inventory + Closing inventory) ÷ 2
  • Opening inventory value = 1,200 × 25.00=25.00 = 30,000
  • Closing inventory value = 1,800 × 26.54=26.54 = 47,772
  • Average inventory = (30,000+30,000 + 47,772) ÷ 2 = $38,886
  • Inventory turnover ratio = Cost of sales ÷ Average inventory
  • Inventory turnover ratio = 103,506÷103,506 ÷ 38,886 = 2.66 times (to 2 decimal places)

Answer: 2.66 times [2]

Marking notes: 1 mark for correct average inventory calculation, 1 mark for correct ratio calculation and answer to 2 decimal places. Common error: using closing inventory only instead of average inventory.

Cost of sales$321,000+$700$321,700
Gross profit$159,000-$700$158,300

Answer: $158,300 [3]

Marking notes: 1 mark for correct cost of goods available, 1 mark for correct cost of sales using corrected closing inventory, 1 mark for correct gross profit. Follow-through from (a) allowed.

(c) Correct Profit for the Year [3 marks]

Workings:

  • Correct gross profit = $158,300
  • Operating expenses = $95,000
  • Profit for the year = 158,300−158,300 - 95,000 = $63,300

Answer: $63,300 [3]

Marking notes: 1 mark for correct formula, 1 mark for correct operating expenses figure, 1 mark for final answer. Follow-through from (b) allowed.

Question 5

(a) Closing Inventory at Lower of Cost and NRV [3 marks]

Workings:

Total400$9,300$8,600

Answer: $8,600 [3]

Marking notes: 1 mark for identifying NRV ($21.50) is lower than both cost layers, 1 mark for correct calculation per layer, 1 mark for correct total. Common error: applying write-down only to the higher cost layer.

(b) Accounting Principle [2 marks]

Answer:

  • Principle: Prudence (Conservatism) Concept
  • Explanation: The prudence concept requires that assets should not be overstated and profits should not be anticipated. Inventory is valued at the lower of cost and net realisable value to ensure that any potential losses from decline in inventory value are recognised immediately, while gains are only recognised when realised. This prevents overstatement of assets and profit in the financial statements.

[2 marks - 1 mark for naming the principle, 1 mark for correct explanation linking to inventory valuation]

(c) Journal Entry for Write-down [2 marks]

Journal Entry:

DateAccountDebit ($)Credit ($)

Inventory (Statement of Financial Position)700
Being write-down of inventory from cost (9,300)toNRV(9,300) to NRV (8,600)

Workings: Write-down amount = 9,300−9,300 - 8,600 = $700

[2 marks - 1 mark for correct accounts and debit/credit direction, 1 mark for correct amount ($700) and narration. Accept "Cost of Sales" or "Inventory Write-down Expense" as the expense account.]

Question 6

(a) Inventory Turnover Ratio [3 marks]

Workings:

Alpha Ltd:

  • Average inventory = (50,000+50,000 + 70,000) ÷ 2 = $60,000
  • Inventory turnover = 360,000÷360,000 ÷ 60,000 = 6.00 times

Beta Ltd:

  • Average inventory = (70,000+70,000 + 50,000) ÷ 2 = $60,000
  • Inventory turnover = 420,000÷420,000 ÷ 60,000 = 7.00 times

Answer: Alpha Ltd: 6.00 times; Beta Ltd: 7.00 times [3]

Marking notes: 1 mark for Alpha calculation, 1 mark for Beta calculation, 1 mark for both correct to 2 decimal places.

(b) Days Sales in Inventory [3 marks]

Workings:

Formula: Days sales in inventory = (Average inventory ÷ Cost of sales) × 365 OR = 365 ÷ Inventory turnover ratio

Alpha Ltd:

  • Days sales in inventory = 365 ÷ 6.00 = 60.83 days

Beta Ltd:

  • Days sales in inventory = 365 ÷ 7.00 = 52.14 days

Answer: Alpha Ltd: 60.83 days; Beta Ltd: 52.14 days [3]

Marking notes: 1 mark for Alpha, 1 mark for Beta, 1 mark for both correct to 2 decimal places. Follow-through from (a) allowed.

(c) Comment on Inventory Management Efficiency [3 marks]

Answer: Beta Ltd has a higher inventory turnover ratio (7.00 times vs 6.00 times) and lower days sales in inventory (52.14 days vs 60.83 days), indicating that Beta Ltd sells and replenishes its inventory more quickly than Alpha Ltd. This suggests Beta Ltd has more efficient inventory management - it holds inventory for a shorter period, reducing holding costs, obsolescence risk, and tied-up capital. However, Alpha Ltd achieves a higher gross profit margin (40% vs 30%), so the slower turnover may be a deliberate strategy for higher-margin products. Beta Ltd's faster turnover with lower margins suggests a high-volume, low-margin business model.

[3 marks - 1 mark for identifying Beta is more efficient based on ratios, 1 mark for explaining what the ratios mean (holding period, holding costs), 1 mark for balanced comment acknowledging trade-off with profit margins]

    • Cost of sales: $552,500
    • Gross profit = $287,500
    • Operating expenses: $150,000
    • Profit before tax = $137,500
    • Tax (17%): 137,500×0.17=137,500 × 0.17 = 23,375
    • Profit for the year = $114,125

Answer: Cost of sales = 552,500;Grossprofit=552,500; Gross profit = 287,500; Profit for the year = $114,125 [6]

Marking notes: 2 marks for correct cost of sales with workings, 1 mark for gross profit, 1 mark for profit before tax, 1 mark for tax calculation, 1 mark for profit for the year.

(b) AVCO Calculations [6 marks]

Workings:

  1. Weighted Average Cost per Unit:

    • Opening: 200 × 500=500 = 100,000
    • Mar: 500 × 520=520 = 260,000
    • Jul: 400 × 550=550 = 220,000
    • Nov: 300 × 580=580 = 174,000
    • Total cost = $754,000
    • Total units = 1,400
    • Average cost = 754,000÷1,400=754,000 ÷ 1,400 = 538.5714... ≈ $538.57 (to 2 decimal places)

  2. AVCO Cost of Sales:

    • Units sold = 1,050
    • Cost of sales = 1,050 × 538.57=538.57 = 565,498.50

  3. AVCO Closing Inventory:

    • Units = 350
    • Closing inventory = 350 × 538.57=538.57 = 188,499.50

  4. Profit Calculation:

    • Revenue = $840,000
    • Cost of sales = $565,498.50
    • Gross profit = $274,501.50
    • Operating expenses = $150,000
    • Profit before tax = $124,501.50

(c) Advice on Switching from FIFO to AVCO [3 marks]

Answer:

Recommendation: Do not switch (or switch only with full disclosure and consistent application).

Reasons:

  1. Reported Profit Impact: FIFO gives higher profit (114,125vs114,125 vs 103,336) because in rising prices, FIFO assigns older, lower costs to cost of sales. Switching to AVCO would reduce reported profit by $10,789, which may concern shareholders.

  2. Tax Liability: Lower profit under AVCO means lower tax expense (21,165vs21,165 vs 23,375), saving $2,210 in tax. This is a cash flow advantage but reduces retained earnings.

  3. Statement of Financial Position: FIFO closing inventory (201,500)isclosertocurrentreplacementcostthanAVCO(201,500) is closer to current replacement cost than AVCO (188,500). FIFO provides a more realistic asset valuation in inflationary periods.

  4. Consistency Principle: The company has been using FIFO. Changing to AVCO violates the consistency principle unless there is a valid reason and the change is disclosed with restatement of comparatives. Frequent changes reduce comparability and reliability of financial statements.

Overall: The switch reduces profit and inventory valuation quality for a modest tax saving. Consistency and comparability favour retaining FIFO. If changed, full disclosure and retrospective application are required.
