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

TuitionGoWhere Exam Practice (AI)

Subject: Principles of Accounts
Level: O-Level (7087)
Paper: Practice Paper (Version 2 of 5)
Topic: Inventory Costing

Section A: Multiple Choice & Short Concepts [10 Marks]

Question 1
Answer: C [1]
Reasoning: The prudence concept dictates that assets should not be overstated. If NRV is lower than cost, the inventory value must be written down to NRV.

Question 2
Answer: A [1]
Reasoning: In a period of rising prices, FIFO assumes the older, cheaper units are sold first, leaving the newer, more expensive units in closing inventory.

Question 3
Answer:
Net Realisable 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 reference, 1 mark for deduction of costs)

Question 4
Answer:
Any one of the following:

It smooths out price fluctuations.
It is easier to calculate/administer than FIFO or LIFO.
It is often required by tax authorities in certain jurisdictions.
It prevents manipulation of profit by selecting specific batches. [1]

Question 5
Answer: C [1]
Reasoning: Goods on consignment belong to the consignor (owner), not the consignee (holder). Therefore, they are excluded from the holder's inventory.

Question 6
Answer: B [1]
Reasoning: Cost of Sales = Opening Inventory + Purchases - Closing Inventory. If Opening Inventory is overstated, Cost of Sales is overstated. If Cost of Sales is overstated, Gross Profit is understated.

Question 7
Answer: $50,000 [1] *Workings:* Cost of Sales = Opening Inventory ($ 12,000) + Purchases ( $45,000) + Carriage Inwards ($ 1,500) - Closing Inventory ( $8,500) =$ 58,500 - $8,500 =$ 50,000.

Question 8
Answer: B [1]
Reasoning: The Prudence concept ensures that assets and profits are not overstated.

Question 9
Answer: False [1]
Reasoning: Under FIFO, the Cost of Goods Sold reflects the oldest purchase prices. The Closing Inventory reflects the most recent prices.

Question 10
Answer: $400 [1] *Workings:* NRV = Selling Price ($ 500) - Selling Costs ( $100) =$ 400.
Cost = $2,000. Lower of Cost ($ 2,000) and NRV ( $400) is$ 400.

Section B: Calculations and Application [20 Marks]

Question 11

(a) Calculate the value of the Closing Inventory as at 31 March 2024 using the FIFO method.

Step 1: Determine Units in Closing Inventory

Opening Balance: 100 units
Purchases: 200 + 100 + 50 = 350 units
Total Available: 450 units
Sales: 150 + 120 = 270 units
Closing Inventory Units: 450 - 270 = 180 units

Step 2: Value Closing Inventory using FIFO
Under FIFO, the closing inventory consists of the most recently purchased units. We work backwards from the last purchase.

From 25 Mar Purchase:
50 units @ $14.00 =$ 700.00
(Remaining units needed: 180 - 50 = 130 units)
From 15 Mar Purchase:
100 units @ $13.00 =$ 1,300.00
(Remaining units needed: 130 - 100 = 30 units)
From 5 Mar Purchase:
30 units @ $12.00 =$ 360.00
(Note: The 5 Mar purchase had 200 units. 150 were sold on 10 Mar? No, let's trace flow carefully below to ensure accuracy, though working backwards from end is valid for FIFO Closing Stock).

Verification of Flow (FIFO):

10 Mar Sale (150 units):
- 100 units from Opening Balance (@ $10.00)
- 50 units from 5 Mar Purchase (@ $12.00)
- Remaining from 5 Mar Purchase: 200 - 50 = 150 units.
20 Mar Sale (120 units):
- 120 units from remaining 5 Mar Purchase (@ $12.00)
- Remaining from 5 Mar Purchase: 150 - 120 = 30 units.
Closing Inventory Composition:
- 30 units from 5 Mar Purchase @ $12.00 =$ 360.00
- 100 units from 15 Mar Purchase @ $13.00 =$ 1,300.00
- 50 units from 25 Mar Purchase @ $14.00 =$ 700.00

Total Closing Inventory Value:
$360 +$ 1,300 + $700 = **$ 2,360**

Answer: $2,360 [10]
(Award marks for: Correct unit count [2], Correct identification of layers [4], Correct calculations [4])

(b) Calculate the Gross Profit for March 2024.

Step 1: Calculate Total Sales Revenue

10 Mar: 150 units @ $25.00 =$ 3,750
20 Mar: 120 units @ $25.00 =$ 3,000
Total Sales: $6,750

Step 2: Calculate Cost of Sales (COS)

Method 1: Opening Inventory + Purchases - Closing Inventory
- Opening Inventory: 100 @ $10 =$ 1,000
- Purchases:
  - 200 @ $12 =$ 2,400
  - 100 @ $13 =$ 1,300
  - 50 @ $14 =$ 700
  - Total Purchases = $4,400
- Goods Available for Sale = $1,000 +$ 4,400 = $5,400
- Less Closing Inventory = $2,360
- Cost of Sales = $5,400 -$ 2,360 = $3,040
Method 2: Sum of specific costs sold (FIFO)
- Sale 1 (150 units): (100 @ $10) + (50 @$ 12) = $1,000 +$ 600 = $1,600
- Sale 2 (120 units): (120 @ $12) =$ 1,440
- Cost of Sales = $1,600 +$ 1,440 = $3,040

Step 3: Calculate Gross Profit

Gross Profit = Sales - Cost of Sales
Gross Profit = $6,750 -$ 3,040
Gross Profit = $3,710

Answer: $3,710 [10]
(Award marks for: Correct Sales calculation [2], Correct COS calculation [6], Correct Gross Profit [2])
