Answer Key & Marking Scheme (Version 2)

Topic: Inventory Costing & Valuation Total Marks: 40

Section A: Multiple Choice & Short Concepts (10 Marks)

1. B (Prudence Concept) [1]

2. A (FIFO) Reasoning: In rising prices, FIFO leaves the most recent (higher) costs in closing inventory. [1]

3. Net Realizable Value (NRV) is the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale. [2] (1 mark for selling price, 1 mark for less costs to sell)

4. Any one of the following:

It smooths out price fluctuations.
It is easier to calculate/administer than FIFO if records are not perpetual.
It is often seen as a fairer reflection of cost when items are indistinguishable. [1]

5. A (The Consignor) [1]

6. B (Understated by $500) Reasoning: Cost of Sales = Opening Inv + Purchases - Closing Inv. If Opening Inv is high, Cost of Sales is high. If Cost of Sales is high, Gross Profit is low. [1]

7. * $51,000** *Workings:$ 12,000 + $45,000 +$ 2,000 - $8,000 =$ 51,000. [1]

8. C (Carriage outwards to customers) Reasoning: This is a selling expense, not a cost of bringing inventory to its present location/condition. [1]

9. B (Oldest purchases) [1]

Section B: Structured Calculations (20 Marks)

10. TechParts Pte Ltd (FIFO)

(a) Closing Inventory Value

Total Units Available: 100 + 200 + 100 = 400 units
Total Units Sold: 150 + 180 = 330 units
Closing Units: 400 - 330 = 70 units
Under FIFO, closing inventory consists of the most recent purchases.
The last purchase was 100 units @ $14.00.
We have 70 units remaining from this batch.
Value = 70 units × $14.00 = **$ 980** [4] (1 mark for identifying remaining units, 1 mark for identifying correct batch, 1 mark for calculation, 1 mark for final answer)

(b) Cost of Sales

Method 1: Opening Inv + Purchases - Closing Inv
- Opening: 100 × $10 =$ 1,000
- Purch 1: 200 × $12 =$ 2,400
- Purch 2: 100 × $14 =$ 1,400
- Total Goods Available: $4,800
- Less Closing Inv: $980
- Cost of Sales = $4,800 -$ 980 = $3,820
Method 2: Sum of specific costs sold
- Sale 1 (150 units): 100 @ $10 + 50 @$ 12 = $1,000 +$ 600 = $1,600
- Sale 2 (180 units): 150 @ $12 (remaining from Purch 1) + 30 @$ 14 = $1,800 +$ 420 = $2,220
- Total COS = $1,600 +$ 2,220 = $3,820 [2] (1 mark for workings, 1 mark for answer)

(c) Gross Profit

Gross Profit = Revenue - Cost of Sales
Gross Profit = $6,000 -$ 3,820 = $2,180 [2] (1 mark for formula/substitution, 1 mark for answer)

11. GreenGrocers (AVCO)

(a) Weighted Average Cost after 10 April Purchase

Opening Inventory: 500 units @ $4.00 =$ 2,000
Purchase (10 Apr): 300 units @ $5.00 =$ 1,500
Total Value: $3,500
Total Units: 800
Average Cost = $3,500 / 800 = **$ 4.375** (or $4.38 if rounded, but keep precision for next step) [2] (1 mark for total value/units, 1 mark for division)

(b) Closing Inventory Value at 30 April

Sale (15 Apr): 400 units sold.
Remaining Units after sale: 800 - 400 = 400 units.
Value of remaining units: 400 × $4.375 =$ 1,750.
Purchase (25 Apr): 200 units @ $6.00 =$ 1,200.
New Total Units: 400 + 200 = 600 units.
New Total Value: $1,750 +$ 1,200 = $2,950.
New Average Cost (if needed for future sales): $2,950 / 600 =$ 4.916...
Closing Inventory Value = $2,950 [4] (1 mark for value after first sale, 1 mark for adding new purchase, 1 mark for total value, 1 mark for final answer)

(c) Cost of Sales for 15 April Sale

Units Sold: 400
Cost per unit (from part a): $4.375
Cost of Sales = 400 × $4.375 = **$ 1,750** [2] (1 mark for using correct avg cost, 1 mark for answer)

12. FashionHub

(a) Gross Profit

Gross Profit = Revenue × Gross Profit Margin
Gross Profit = $200,000 × 40% = **$ 80,000** [1]

(b) Cost of Sales

Cost of Sales = Revenue - Gross Profit
Cost of Sales = $200,000 -$ 80,000 = $120,000 [1]

(c) Purchases

Formula: Cost of Sales = Opening Inventory + Purchases - Closing Inventory
$120,000 =$ 15,000 + Purchases - $25,000
$120,000 = Purchases -$ 10,000
Purchases = $120,000 +$ 10,000 = $130,000 [2] (1 mark for correct rearrangement/workings, 1 mark for answer)

Section C: Analysis and Evaluation (10 Marks)

13. BuildIt Co. (FIFO vs AVCO in Rising Prices)

(a) Effect on Closing Inventory

Changing from FIFO to AVCO would decrease the value of Closing Inventory.
FIFO values closing inventory at the most recent (higher) prices. AVCO averages the older (lower) prices with the newer (higher) prices, resulting in a lower unit cost than FIFO in a rising market. [2] (1 mark for direction "decrease", 1 mark for explanation)

(b) Effect on Net Profit

Net Profit would decrease.
Because Closing Inventory is lower under AVCO, the Cost of Sales will be higher (COS = Op + Purch - Cl). Higher Cost of Sales results in lower Gross Profit and consequently lower Net Profit. [2] (1 mark for direction "decrease", 1 mark for link to COS)

(c) Advantages of AVCO for BuildIt Co.

Advantage 1: Smoothing of Price Fluctuations. AVCO prevents sharp swings in profit margins that can occur with FIFO when material prices are volatile. This provides a more stable view of performance for stakeholders.
Advantage 2: Practicality for Homogeneous Goods. For materials like cement or steel, it is often impossible to distinguish which specific batch is being used. AVCO reflects the physical flow of mixed inventory better than FIFO, which assumes specific order of usage.
(Other acceptable answers: Easier to administer if perpetual records are not kept; accepted by tax authorities in some jurisdictions as a reasonable approximation.) [4] (2 marks per advantage: 1 for identification, 1 for explanation/context)

14. ElectroStore (Damaged Goods)

(a) Inventory Value

$200 (The Net Realizable Value) [1]

(b) Accounting Concept

Prudence Concept (or Conservatism).
Assets should not be overstated. Inventory must be valued at the lower of cost ( $2,000) and NRV ($ 200). [1] (1 mark for naming the concept)
