Total Cost of Sales$10,400

Marking:

  • 1 mark for correct Mar 15 cost of sales calculation
  • 1 mark for correct Mar 28 cost of sales calculation
  • 1 mark for correct total

(a) (ii) Closing Inventory – FIFO Method (1 mark)

Remaining after Mar 28 sale: 300 units from Mar 20 purchase (400 − 100 used) Closing inventory = 300 × 20=∗∗20 = **6,000**

Marking: 1 mark for correct closing inventory value.

(b) (i) Cost of Sales – AVCO Method (4 marks)

Mar 20Purchase400 × 20=20 = 8,000
Balance650 units, $12,20012,200 ÷ 650 = 18.77 (approx.)
Mar 28Sale 350350 × $18.77Cost = $6,569.50
Total Cost of Sales$10,769.50

Note: Accept 10,769or10,769 or 10,770 depending on rounding. Consistent rounding must be applied.

Marking:

Remaining: 300 units × 18.77=∗∗18.77 = **5,631** (or $5,630 depending on rounding)

Marking: 1 mark for correct closing inventory value consistent with candidate's AVCO calculation.

(c) Advantage of FIFO (1 mark)

Any one of:

  • FIFO is simpler and easier to calculate than AVCO.
  • FIFO values closing inventory at the most recent purchase prices, which more closely reflects current market value.
  • FIFO is less prone to manipulation as it follows the physical flow of goods for most businesses.

Marking: 1 mark for any valid advantage.

Question 2: Lower of Cost and Net Realisable Value (5 marks)

(a) Accounting Concept (1 mark)

Prudence Concept (or Conservatism Concept).

Marking: 1 mark for correct concept.

Question 3: Effects of Inventory Errors (5 marks)

(a) Effects of Errors (4 marks)

ErrorEffect on Gross ProfitEffect on Current Assets
1No effect (Purchases understated but closing inventory understated by same amount; COGS unchanged)Understated by $2,500 (Inventory understated)
2Overstated by $1,800 (Closing inventory overstated → COGS understated → Gross profit overstated)Overstated by $1,800 (Inventory overstated)
3**Overstated by 700∗∗(700** (900 − $200; Closing inventory overstated → COGS understated → Gross profit overstated)**Overstated by 700∗∗(Inventoryoverstatedby700** (Inventory overstated by 700)

Marking:

  • 1 mark for each error with both effects correct (3 × 1 = 3 marks)
  • 1 additional mark for all six cells correct

(b) Total Effect on Gross Profit (1 mark)

Overstatement of gross profit = 1,800+1,800 + 700 = $2,500 overstated

Marking: 1 mark for correct total and direction (overstated).

Question 4: Inventory Turnover and Days Sales in Inventory (5 marks)

(a) (i) Inventory Turnover Ratio (2 marks)

20242025
Average Inventory(40,000+40,000 + 50,000) ÷ 2 = $45,000(50,000+50,000 + 70,000) ÷ 2 = $60,000
Inventory Turnover350,000÷350,000 ÷ 45,000 = 7.78 times450,000÷450,000 ÷ 60,000 = 7.50 times

Marking:

  • 1 mark for correct average inventory calculations
  • 1 mark for correct turnover ratios

(a) (ii) Days Sales in Inventory (2 marks)

20242025
Days Sales in Inventory365 ÷ 7.78 = 47 days (or 46.92)365 ÷ 7.50 = 49 days (or 48.67)

Marking:

  • 1 mark for correct 2024 days
  • 1 mark for correct 2025 days

(b) Comment on Efficiency (1 mark)

Inventory management efficiency has worsened slightly. Days sales in inventory increased from 47 days to 49 days, meaning inventory is being held for longer before being sold. The inventory turnover ratio decreased from 7.78 to 7.50 times, indicating slower inventory movement.

Marking: 1 mark for correct observation with reference to the change.

Question 5: Inventory Decision-Making Scenario (5 marks)

(a) Net Cash Inflow – Option A (2 marks)

$
Selling price after 10% discount: $40,000 × 90%36,000
Less: Cost of inventory(30,000)
Gross cash inflow6,000
Interest saved on overdraft (not directly part of cash inflow from sale)—
Net cash inflow from Option A$36,000

Note: The question asks for net cash inflow. Accept 36,000(totalcashreceived)or36,000 (total cash received) or 6,000 (profit on sale). Award marks for clear working showing understanding.

Marking:

  • 1 mark for correct discounted selling price
  • 1 mark for correct net cash inflow

(b) Advantage and Disadvantage of Option A (2 marks)

Advantage:

  • Immediate cash inflow of 36,000improvesliquidityquicklyandreducesthebankoverdraft,savinginterestcostsofapproximately36,000 improves liquidity quickly and reduces the bank overdraft, saving interest costs of approximately 240 per month ($36,000 × 8% ÷ 12). This is faster than waiting six months under Option B.

Disadvantage:

  • The business loses 4,000inpotentialrevenue(4,000 in potential revenue (40,000 − 36,000)byofferingthediscount.UnderOptionB,thefull36,000) by offering the discount. Under Option B, the full 40,000 would eventually be received.

Marking:

  • 1 mark for a valid advantage with explanation
  • 1 mark for a valid disadvantage with explanation

(c) Recommendation (1 mark)

Recommend Option A (or Option B with valid justification).

Example for Option A: Option A is recommended because the immediate cash inflow of 36,000willreducethebankoverdraftandsaveinterestcosts.Although36,000 will reduce the bank overdraft and save interest costs. Although 4,000 in revenue is lost, the interest savings and improved liquidity position outweigh this cost, especially if the business is facing cash flow difficulties.

Example for Option B: Option B is recommended because the business retains the full 40,000inrevenue.Ifthebusinesscanmanageitscashflowforsixmonths,theadditional40,000 in revenue. If the business can manage its cash flow for six months, the additional 4,000 in profit is more beneficial than the interest savings from early sale.

Marking: 1 mark for a clear recommendation with a justified reason linked to the scenario.

Total: 40 marks
