Secondary 4 Principles of Accounts – SA1 Practice Paper (Version 1)

Total Marks: 40

Section A: Structured Questions

Question 1
Definition: Inventory Turnover Rate measures how many times a business sells and replaces its inventory during a specific period.
(1 mark for "how many times sold/replaced", 1 mark for "during a period")
[2 marks]

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

Question 3
Reason: During rising prices, FIFO assigns older (lower) costs to Cost of Sales, resulting in a higher reported Gross Profit. This may be desirable for reporting better performance to shareholders or securing loans.
(1 mark for identifying higher profit/lower COGS, 1 mark for context of rising prices)
[2 marks]

Question 4
Calculation of Cost of Sales:
Opening Inventory: $12,000 Add: Purchases:$85,000
Less: Purchases Returns: ($3,000) Add: Carriage Inwards:$2,500
Cost of Goods Available for Sale: $96,500 Less: Closing Inventory: ($15,500)
Cost of Sales: $81,000

(1 mark for correct net purchases/carriage adjustment, 1 mark for correct formula structure, 1 mark for final answer)
[3 marks]

Question 5
(a) Gross Profit is Overstated by $4,000. (b) Current Assets are **Overstated** by$4,000.
(1 mark for each correct effect)
[2 marks]

Question 6
Workings:
Average Inventory = (Opening + Closing) / 2
= ($18,000 +$22,000) / 2 = $20,000 Inventory Turnover Rate = Cost of Sales / Average Inventory =$120,000 / $20,000
= 6.0 times

(1 mark for average inventory, 1 mark for formula application, 1 mark for answer)
[3 marks]

Question 7
AVCO Calculation:

1. Total Value before sale:
   (100 units × $10) + (200 units ×$12) = $1,000 +$2,400 = $3,400
   Total Units = 300
2. Weighted Average Cost per unit:
   $3,400 / 300 units =$11.333... (keep precision)
3. Units Sold: 150
   Units Remaining: 300 - 150 = 150 units
4. Value of Closing Inventory:
   150 units × $11.333... = **$1,700**

(1 mark for total value pre-sale, 1 mark for avg cost calc, 1 mark for remaining units, 1 mark for final value)
[4 marks]

Question 8
FIFO Calculation:

1. Sale of 120 units on 15 Jan:
   • First 50 units from Opening Balance @ $20 =$1,000
   • Next 70 units from 10 Jan Purchase @ $22 =$1,540
   • Remaining from 10 Jan Purchase: 100 - 70 = 30 units @ $22
2. Closing Inventory consists of:
   • 30 units @ $22 =$660
   • 80 units @ $25 (from 25 Jan purchase) =$2,000
3. Total Value: $660 +$2,000 = $2,660

(1 mark for identifying flow of goods, 1 mark for remaining 30 units val, 1 mark for new purchase val, 1 mark for total)
[4 marks]

Question 9
Comment: The turnover rate has decreased from 8.0 to 5.5 times, indicating inventory is moving slower.
Reasons (Any two):

1. Overstocking / Purchasing too much inventory.
2. Decrease in sales demand / Poor marketing.
3. Obsolete or outdated stock.
4. Increase in closing inventory levels without proportional sales increase.
   (1 mark for comment on decrease/slower movement, 1 mark for each valid reason up to 2)
   [4 marks]

Question 10
(a) Carriage Inwards appears in the Trading Account (part of Cost of Sales). Carriage Outwards appears in the Income Statement (as an operating expense).
(b) Carriage Inwards reduces Gross Profit (by increasing COGS). Carriage Outwards does not affect Gross Profit (it affects Net Profit).
(1 mark for each correct part a and b explanation)
[4 marks]

Question 11
Item A: Lower of $50 and$45 = $45 Item B: Lower of$30 and $35 =$30
Total Value = $45 +$30 = $75
(1 mark for correct selection of Item A, 1 mark for correct selection of Item B/Total)
[2 marks]

Question 12
Any two of:

1. Purchase price of goods.
2. Import duties/taxes.
3. Carriage Inwards (transport costs to bring to location).
4. Handling costs directly attributable to acquisition.
   (1 mark for each valid cost)
   [2 marks]

Question 13
(a) Gross Profit will Decrease (because AVCO uses higher recent costs in COGS compared to FIFO's older lower costs).
(b) Closing Inventory value will Decrease (because older, cheaper costs remain in inventory under AVCO vs FIFO).
(1 mark for each correct direction)
[2 marks]

Question 14
Gross Profit = Revenue - Cost of Sales = $200,000 -$140,000 = $60,000 Gross Profit Margin = (Gross Profit / Revenue) × 100= ($60,000 / $200,000) × 100%
= 30%
(1 mark for GP calc, 1 mark for final %)
[2 marks]

Question 15
Too much: High storage/holding costs, risk of obsolescence/theft, tied up capital.
Too little: Lost sales opportunities, inability to meet customer demand, stoppage of production.
(1 mark for each valid disadvantage)
[2 marks]

Question 16
Workings:

1. Cost of Sales = Opening + Purchases - Closing
   = $10,000 +$60,000 - $14,000 =$56,000
2. Average Inventory = ($10,000 +$14,000) / 2 = $12,000
3. Inventory Holding Period = (Average Inventory / Cost of Sales) × 365
   = ($12,000 /$56,000) × 365
   = 0.21428... × 365
   = 78.2 days (or 78 days)

(1 mark for COGS, 1 mark for Avg Inv, 1 mark for final answer)
[3 marks]

Question 17

1. Investors/Shareholders: To assess profitability and management efficiency.
2. Tax Authorities (IRAS): To verify correct profit calculation for tax purposes.
3. Management: To make decisions on pricing and stock control.
   (1 mark for each user with valid reason)
   [2 marks]

Question 18
Net Profit will Increase by $2,000.
(Closing inventory was understated, so COGS was overstated, so Profit was understated. Correction increases profit.)
[1 mark]

Question 19
LIFO does not reflect the physical flow of goods in most industries and can result in outdated inventory values on the Statement of Financial Position. (Or: It is not permitted by IFRS/SG-FRS).
[1 mark]

Question 20
Method: FIFO.
Reason: Perishable goods must be sold in the order they are acquired to prevent spoilage. FIFO matches the physical flow of goods (oldest stock sold first).
(1 mark for FIFO, 1 mark for reason linking to perishability/physical flow)
[2 marks]
