Answer Key and Marking Scheme
Assessment: SA1 (Version 5)
Topic: Inventory Costing

Section A: Structured Questions (20 Marks)

Question 1
Answer: Inventory Turnover is a ratio that measures how many times a business sells and replaces its inventory over a specific period.
Marks: [1]
Note: Accept "Number of times inventory is sold/replaced in a year".

Question 2
Answer: Prudence Concept (or Conservatism Concept).
Marks: [1]

Question 3
Answer:

FIFO assigns the oldest (lower) costs to Cost of Sales.
This results in a lower Cost of Sales and therefore a higher Gross Profit/Net Profit during periods of rising prices.
It also reflects the physical flow of goods for perishable items.
Marks: [2]
1 mark for identifying lower COGS/higher profit, 1 mark for explanation or physical flow.

Question 4
Answer:

Carriage Inwards: Added to Purchases in the Trading Account (part of Cost of Sales). It is a direct cost of acquiring inventory.
Carriage Outwards: Recorded as an Operating Expense in the Income Statement (below Gross Profit). It is a selling/distribution expense.
Marks: [2]
1 mark for correct treatment of Carriage Inwards, 1 mark for Carriage Outwards.

Question 5
Answer:
(a) Cost of Sales will be Understated.
(b) Net Profit will be Overstated.
Marks: [2]
1 mark for each correct effect.

Section B: Calculations and Applications (20 Marks)

Question 6
Workings:
Opening Inventory: $12,500 Add: Purchases:$ 85,000
Less: Purchases Returns: ( $2,500) Add: Carriage Inwards:$ 1,200
Cost of Goods Available for Sale: $96,200 Less: Closing Inventory: ($ 14,800)
Cost of Sales: $81,400

Answer: $81,400
Marks: [3]
1 mark for correct Net Purchases/COGAS structure, 1 mark for correct arithmetic, 1 mark for final answer.

Question 7
Workings:
Revenue: $120,000 Less: Cost of Sales:$ 81,400
Gross Profit: $38,600

Answer: $38,600
Marks: [2]
1 mark for formula/substitution, 1 mark for answer.

Question 8
Workings:
Average Inventory = (Opening Inventory + Closing Inventory) / 2
= ( $12,500 +$ 14,800) / 2
= $27,300 / 2 =$ 13,650

Inventory Turnover = Cost of Sales / Average Inventory
= $81,400 /$ 13,650
= 5.9633...

Answer: 5.96 times
Marks: [3]
1 mark for Average Inventory calculation, 1 mark for formula application, 1 mark for correct answer to 2 d.p.

Question 9
Answer:

QuickMart has a much higher inventory turnover rate (12.5 times) compared to SlowStock Ltd (4.2 times).
This indicates that QuickMart is more efficient in managing its inventory, selling its stock faster.
SlowStock Ltd holds inventory for a longer period, which may lead to higher holding costs or risk of obsolescence.
Marks: [3]
1 mark for comparison of figures, 1 mark for interpreting QuickMart's efficiency, 1 mark for interpreting SlowStock's inefficiency/risk.

Question 10
Answer:

QuickMart has a lower Gross Profit Margin (20%) but high turnover. This suggests a "high volume, low margin" strategy (e.g., discount retailer).
SlowStock Ltd has a higher Gross Profit Margin (35%) but low turnover. This suggests a "low volume, high margin" strategy (e.g., luxury or niche specialist).
The difference in margin compensates for the difference in turnover speed.
Marks: [2]
1 mark for linking low margin to high volume/turnover, 1 mark for linking high margin to low volume/turnover.

Question 11
Workings (FIFO):
Total Units Available: 100 + 50 + 60 = 210 units
Total Units Sold: 80 + 40 = 120 units
Closing Inventory Units: 210 - 120 = 90 units

Under FIFO, the closing inventory consists of the most recently purchased units.

60 units from 15 Jan purchase @ $430 =$ 25,800
Remaining 30 units from 5 Jan purchase @ $420 =$ 12,600
(Note: The 100 units from 1 Jan and 20 units from 5 Jan were sold first)

Total Value = $25,800 +$ 12,600 = $38,400

Answer: $38,400
Marks: [4]
1 mark for identifying closing units (90), 1 mark for identifying correct layers (60 @ 430, 30 @ 420), 1 mark for calculations, 1 mark for final answer.

Question 12
Workings (AVCO):

Before 10 Jan Sale:
- Opening: 100 @ $400 =$ 40,000
- Purchase 5 Jan: 50 @ $420 =$ 21,000
- Total: 150 units, Value $61,000
- Avg Cost: $61,000 / 150 =$ 406.67 per unit
- Sale 10 Jan: 80 units sold. Remaining: 70 units @ $406.67 =$ 28,466.90 (keep precision for next step)
Before 20 Jan Sale:
- Balance: 70 units @ $406.66... =$ 28,466.67
- Purchase 15 Jan: 60 @ $430 =$ 25,800
- Total: 130 units, Value $54,266.67
- New Avg Cost: $54,266.67 / 130 =$ 417.435... -> Round to $417.44 per unit (if rounding at each step) OR keep precise.
  Let's use standard exam practice: Recalculate average after each purchase.
Alternative Calculation (Weighted Average of all goods available for sale is NOT used in perpetual AVCO usually, but often in periodic. Assuming Perpetual as dates are given):

Let's re-calculate carefully with 2 d.p. rounding at each average step as per common secondary syllabus:
- Step 1 Avg: $61,000 / 150 =$ 406.67
- Inventory after sale 1: 70 units @ $406.67 =$ 28,466.90
- Step 2 Total Value: $28,466.90 +$ 25,800 = $54,266.90
- Step 2 Total Units: 70 + 60 = 130
- Step 2 Avg: $54,266.90 / 130 =$ 417.437... -> $417.44
- Closing Inventory: 90 units (130 - 40 sold) @ $417.44 =$ 37,569.60
If Periodic AVCO was assumed (simpler):
- Total Cost: $40,000 +$ 21,000 + $25,800 =$ 86,800
- Total Units: 210
- Avg: $86,800 / 210 =$ 413.33
- Closing: 90 * $413.33 =$ 37,199.70
Given the specific dates, Perpetual is implied. However, O-Level often accepts Periodic if not specified. Let's provide Perpetual as it is more rigorous for "transactions occurred".

Answer: $37,569.60 (Perpetual) OR$ 37,200 (Periodic approx).
Marking Note: Accept either method if clearly stated. Full marks for correct application of chosen method.
Marks: [4]
1 mark for total units/cost identification, 1 mark for average cost calculation, 1 mark for applying to closing units, 1 mark for final answer.

Question 13
Workings:

Cost per coat: $80
Net Realisable Value (NRV) per coat: Selling Price - Cost to Sell
= $70 -$ 5 = $65
Lower of Cost ( $80) and NRV ($ 65) is $65.
Total Value: 500 units × $65 =$ 32,500

Answer: $32,500
Marks: [3]
1 mark for NRV calculation, 1 mark for comparison (lower of cost/NRV), 1 mark for final total.

Question 14
Answer: Net Profit for 2024 will be Understated.
Marks: [1]

Question 15
Answer:

The understated opening inventory (from 2023 error) leads to an understated Cost of Goods Available for Sale.
This results in an understated Cost of Sales for 2024.
Wait, correction:
- 2023 Closing Inventory was understated -> 2023 COGS overstated -> 2023 Profit understated.
- 2024 Opening Inventory is understated (because it equals 2023 Closing).
- Understated Opening Inventory -> Understated COGS (Opening + Purchases - Closing).
- Understated COGS -> Overstated Profit.
  Let's re-evaluate Q14/15 logic.
- Error: 2023 Closing Inventory Understated.
- Effect on 2024: 2024 Opening Inventory is Understated.
- COGS = Opening Inv + Purchases - Closing Inv.
- If Opening Inv is lower, COGS is lower.
- If COGS is lower, Profit is Higher (Overstated).
  Correction to Q14 Answer: Net Profit for 2024 will be Overstated.
  Correction to Q15 Explanation: Because the opening inventory was understated, the Cost of Sales for 2024 was understated, leading to an overstatement of profit.
  Marks: [2]
  1 mark for linking opening inventory to COGS, 1 mark for linking COGS to Profit.

Section C: Scenario-Based Analysis (10 Marks)

Question 16
(a) Advantage of AVCO:

It smooths out price fluctuations, providing a more stable cost of sales and profit figure.
It is less susceptible to manipulation of profit by timing purchases.
Marks: [2]

(b) Disadvantage of AVCO:

It does not reflect the current replacement cost of inventory as closely as FIFO might in rising markets.
Calculations can be more complex and time-consuming than FIFO if done perpetually.
Marks: [2]

(c) Higher Profit in Rising Prices:

FIFO will result in higher reported net profit.
Reason: FIFO charges the older, lower costs to Cost of Sales. Since prices are rising, the recent (higher) costs remain in Closing Inventory. Lower COGS means higher Gross Profit and Net Profit.
Marks: [3]
1 mark for FIFO, 2 marks for explanation (older/lower costs to COGS).

(d) Non-financial factor:

Perishability/Shelf-life of goods (to avoid spoilage/waste).
Customer satisfaction (availability of fresh stock).
Storage space constraints.
Marks: [1]
Any valid non-financial inventory management factor.
