2023 Cambridge IGCSE Accounting (0452) 模拟试题及答案详解

Book-keeping is primarily concerned with the systematic recording of financial transactions (options A, B, and D). Financial statements are prepared to summarize this financial data and provide structured information to help interested parties make informed decisions (option C).

1 mark for the correct option C.

Using the accounting equation: $$\text{Capital} = \text{Total Assets} - \text{Total Liabilities}$$

$$\text{Total Assets} = \text{Non-current assets} + \text{Inventory} + \text{Trade receivables} = \$25000 + \$3400 + \$1900 = \$30300$$

$$\text{Total Liabilities} = \text{Bank overdraft} + \text{Trade payables} = \$1200 + \$2100 = \$3300$$

$$\text{Capital} = \$30300 - \$3300 = \$27000$$

1 mark for the correct calculation leading to option A.

The original entry should have been: Debit rent payable $450, Credit bank $450. The actual entry made was: Credit bank $450, Credit rent payable $450. This caused a double credit of $450, meaning the trial balance credit total is $900 higher than the debit total (so a suspense account was opened with a debit balance of $900). To correct this: we must debit the rent payable account by $900 (this removes the $450 credit error and places the correct $450 debit balance in the account) and credit the suspense account by $900 to close it.

1 mark for identifying the correct correcting entry (option C).

A statement of account is sent by a supplier to a credit customer at the end of the month to show a summary of all invoices, credit notes, payments, and any outstanding balance.

1 mark for the correct answer D.

Both carriage inwards and carriage outwards are expenses deducted in the calculation of the profit for the year (carriage inwards is part of cost of sales, while carriage outwards is an operating expense). Since both are expenses of equal amount ($450), the error of posting carriage inwards as carriage outwards does not change the total expenses. Therefore, there is no effect on the profit for the year, and it remains $18600.

1 mark for identifying that there is no net effect on the profit for the year (option C).

Year 1 depreciation (1 Oct 2020 – 30 Sept 2021) = $$20\% \times \$12000 = \$2400$$
Net Book Value (NBV) on 1 Oct 2021 = $$\$12000 - \$2400 = \$9600$$

Year 2 depreciation (1 Oct 2021 – 30 Sept 2022) = $$20\% \times \$9600 = \$1920$$
Net Book Value (NBV) on 30 Sept 2022 = $$\$9600 - \$1920 = \$7680$$

Loss on disposal = $$\text{Net Book Value} - \text{Disposal Sale Price} = \$7680 - \$7200 = \$480 \text{ loss}$$

1 mark for the correct calculation of loss on disposal (option A).

$$\text{Gross Profit} = 30\% \times \text{Revenue} = 0.30 \times \$120000 = \$36000$$

$$\text{Profit for the year} = \text{Gross Profit} - \text{Expenses} = \$36000 - \$18000 = \$18000$$

$$\text{Profit Margin} = \frac{\text{Profit for the year}}{\text{Revenue}} \times 100 = \frac{\$18000}{\$120000} \times 100 = 15\%$$

1 mark for the correct calculation of profit margin (option B).

To find credit purchases, reconstruct the trade payables account:

$$\text{Credit Purchases} = \text{Closing Trade Payables} + \text{Payments to Suppliers} - \text{Opening Trade Payables}$$

$$\text{Credit Purchases} = \$3800 + \$26500 - \$4200 = \$26100$$

$$\text{Total Purchases} = \text{Credit Purchases} + \text{Cash Purchases} = \$26100 + \$1500 = \$27600$$

1 mark for the correct calculation of total purchases (option C).

To correct the errors:

1. Repairs to plant and machinery (an expense) was incorrectly capitalized (debited to the asset account). Correcting this requires debiting the repairs account, which increases expenses and reduces the draft profit by $1200.
2. Overstated closing inventory understates the cost of sales, thereby overstating profit. Correcting this requires reducing closing inventory, which increases the cost of sales and reduces the draft profit by $800.

Therefore:
$$\text{Corrected profit} = \text{Draft profit} - \text{Repairs error} - \text{Inventory error}$$
$$\text{Corrected profit} = \$48\,000 - \$1200 - \$800 = \$46\,000$$

1 mark for the correct option A.

Let's analyze the correction for each error:

1. Rent was overstated on the debit side by $360 ($510 - $150). To correct this, the Rent account must be credited with $360 and the Suspense account debited with $360.
2. The purchases journal undercast means the total debited to the Purchases account was $200 too low. To correct this, the Purchases account must be debited with $200 and the Suspense account credited with $200.

Combining the entries:
- Debit Purchases account: $200
- Credit Rent account: $360
- Net entry in Suspense account: Debit $360 - Credit $200 = Net Debit of $160.

1 mark for the correct option A.

First, calculate the cost of raw materials consumed:
$$\text{Cost of raw materials consumed} = \text{Opening inventory} + \text{Purchases} + \text{Carriage inwards} - \text{Closing inventory}$$
$$\text{Cost of raw materials consumed} = \$12\,000 + \$85\,000 + \$2500 - \$9500 = \$90\,000$$

Next, calculate the prime cost:
$$\text{Prime cost} = \text{Cost of raw materials consumed} + \text{Direct wages}$$
$$\text{Prime cost} = \$90\,000 + \$42\,000 = \$132\,000$$

Finally, calculate the factory cost of production:
$$\text{Factory cost of production} = \text{Prime cost} + \text{Factory overheads} + \text{Opening work in progress} - \text{Closing work in progress}$$
$$\text{Factory cost of production} = \$132\,000 + \$31\,000 + \$4000 - \$5500 = \$161\,500$$

1 mark for the correct option B.

First, calculate total sales revenue:
$$\text{Total revenue} = \text{Cash sales} + \text{Credit sales} = \$45\,000 + \$75\,000 = \$120\,000$$

Since mark-up is 25% on cost, the cost of sales is:
$$\text{Cost of sales} = \frac{\text{Total revenue}}{1 + \text{mark-up}} = \frac{\$120\,000}{1.25} = \$96\,000$$

We also know that:
$$\text{Cost of sales} = \text{Opening inventory} + \text{Purchases} - \text{Closing inventory}$$
$$\$96\,000 = \$8000 + \text{Purchases} - \$11\,000$$
$$\text{Purchases} = \$96\,000 - \$8000 + \$11\,000 = \$99\,000$$

1 mark for the correct option C.

First, calculate the profit for the year (net profit):
$$\text{Profit for the year} = \text{Gross profit} - \text{Expenses} = \$80\,000 - \$44\,000 = \$36\,000$$

Next, calculate the capital employed:
$$\text{Capital employed} = \text{Total assets} - \text{Current liabilities}$$
$$\text{Capital employed} = (\text{Non-current assets} + \text{Current assets}) - \text{Current liabilities}$$
$$\text{Capital employed} = (\$150\,000 + \$60\,000) - \$30\,000 = \$180\,000$$

Now calculate ROCE:
$$\text{ROCE} = \frac{\text{Profit for the year}}{\text{Capital employed}} \times 100\%$$
$$\text{ROCE} = \frac{\$36\,000}{\$180\,000} \times 100\% = 20\%$$

1 mark for the correct option C.

The purchases ledger control account acts as a summary of trade payables (suppliers).
- The credit side records transactions that increase the amount owed to credit suppliers (e.g., credit purchases, interest charged on overdue accounts).
- The debit side records transactions that decrease the amount owed to credit suppliers (e.g., payments made to suppliers, discount received, purchases returns).
Therefore, purchases returns are recorded on the debit side.

1 mark for the correct option C.

Trade discount is never recorded in the double-entry bookkeeping ledger accounts. Instead, the transaction is recorded at its net cost:
$$\text{Net purchase price} = \$800 - (10\% \times \$800) = \$720$$

To record this credit purchase, the purchaser debits the Purchases account (to record the expense/increase in goods) and credits the credit supplier's account (to record the liability) with the net amount of $720.

1 mark for the correct option A.

First, calculate interest on capital:
- Hale: 6% of $100 000 = $6000
- Geller: 6% of $50 000 = $3000
Total interest on capital = $9000

Next, deduct interest on capital and salary from the profit to find the residual profit:
$$\text{Residual profit} = \text{Profit} - \text{Interest on capital} - \text{Salary to Geller}$$
$$\text{Residual profit} = \$48\,000 - \$9000 - \$15\,000 = \$24\,000$$

Now, distribute the residual profit according to the profit sharing ratio (2 : 1):
- Hale's share = 2/3 of $24 000 = $16 000

The total amount credited to Hale's current account is the sum of his interest on capital and his share of the residual profit:
$$\text{Total credited to Hale's current account} = \$6000 + \$16\,000 = \$22\,000$$

1 mark for the correct option B.

The sales ledger control account is prepared using the totals from the books of prime entry.
- Item 1: A mistake in an individual customer's account in the sales ledger does not affect the books of prime entry totals, so it does not affect the control account.
- Item 2: The total of the sales journal is used to post to the sales ledger control account, so an error in this total requires an adjustment in the control account.
- Item 3: A discount allowed omitted from the cash book means the total of the discount allowed column in the cash book is understated, which affects the amount posted to the sales ledger control account.
Therefore, only items 2 and 3 require an adjustment to the sales ledger control account.

1 mark for the correct option (C).

To calculate the corrected profit:
1. Revenue expenditure on repairs of $800 was incorrectly debited to a non-current asset account. Correcting this introduces an expense of $800, which reduces profit by $800.
2. Closing inventory was understated by $400. Correcting this increases closing inventory, which reduces the cost of sales and increases profit by $400.

Corrected Profit = $14 200 - $800 + $400 = $13 800.

1 mark for the correct option (B).

Factory cost of production is calculated as follows:
1. Prime Cost = Raw materials consumed + Direct wages = $45 000 + $28 000 = $73 000
2. Factory Overheads = Factory supervisors' salaries + Factory rent + Depreciation of factory machinery = $12 000 + $8 000 + $6 000 = $26 000
3. Total Factory Cost = Prime Cost + Factory Overheads = $73 000 + $26 000 = $99 000
4. Factory Cost of Production = Total Factory Cost + Opening Work in Progress - Closing Work in Progress = $99 000 + $3 500 - $2 800 = $99 700.

1 mark for the correct option (B).

We can reconstruct the Trade Payables Account to find the credit purchases (balancing figure):

$$\begin{array}{lr|lr}
\text{Debit} & \$ & \text{Credit} & \$ \\
\hline
\text{Payments} & 38\,500 & \text{Balance b/d} & 6\,400 \\
\text{Discount received} & 1\,200 & \text{Credit Purchases (bal. fig)} & \mathbf{41\,250} \\
\text{Goods returned} & 850 & & \\
\text{Balance c/d} & 7\,100 & & \\
\hline
\text{Total} & 47\,650 & \text{Total} & 47\,650 \\
\end{array}$$

Credit Purchases = $38\,500 + $1\,200 + $850 + $7\,100 - $6\,400 = $41\,250.

1 mark for the correct option (C).

1. Gross Profit = 25% of $120 000 = $30 000
2. Cost of Sales = Revenue - Gross Profit = $120 000 - $30 000 = $90 000
3. Average Inventory = (Opening Inventory + Closing Inventory) / 2 = ($8 000 + $10 000) / 2 = $9 000
4. Rate of Inventory Turnover = Cost of Sales / Average Inventory = $90 000 / $9 000 = 10 times.

1 mark for the correct option (C).

Machinery is a non-current asset, so the machinery account must be debited. Since the machine was bought on credit from Y Limited, the account of the supplier, Y Limited (a liability), must be credited.

1 mark for the correct option (A).

A: Cash received from credit customers is recorded in the cash book.
B: Goods returned by credit customers are recorded in the sales returns journal.
C: Purchase of non-current assets (office equipment) on credit is recorded in the general journal.
D: Sales of goods on credit are recorded in the sales journal.

1 mark for the correct option (C).

1. Calculate Interest on Capital:
- X: 5% of $50 000 = $2 500
- Y: 5% of $30 000 = $1 500
- Total Interest on Capital = $4 000

2. Calculate Residual Profit:
- Residual Profit = $24 000 - $4 000 = $20 000

3. Calculate Y's share of residual profit:
- Y's share = 2/5 of $20 000 = $8 000

4. Calculate Y's total share of profit:
- Total share = Y's Share of Residual Profit + Y's Interest on Capital = $8 000 + $1 500 = $9 500.

1 mark for the correct option (B).

Interest charged to credit customers on overdue accounts increases the amount they owe to the business. Since the sales ledger control account represents the total of trade receivables (which is an asset account), an increase in trade receivables is recorded on the debit side. Therefore, the sales ledger control account must be debited with $45.

Award 1 mark for the correct option A. [1 mark for correct identification of the debit entry of $45]

The cash book was correctly debited with $120. However, the customer's account was credited with $210 instead of $120. This means the customer's account has been credited with an excess of $90 ($210 - $120). To correct this, the customer's account must be debited with $90, and the corresponding credit of $90 must go to the suspense account to balance the correction.

Award 1 mark for the correct option B. [1 mark for correct debit of customer account and credit of suspense account with $90]

Goods returned by a credit customer are returns inwards to the business. These are recorded in the sales returns journal before being posted to the ledger.

Award 1 mark for the correct option B. [1 mark for correct identification of the sales returns journal]

Inventory is valued at the lower of cost and net realisable value for each separate batch:
- Batch X: Lower of $4.50 and $5.00 is $4.50. Value = 100 units * $4.50 = $450
- Batch Y: Lower of $6.00 and $5.50 is $5.50. Value = 150 units * $5.50 = $825
Total inventory value = $450 + $825 = $1275.

Award 1 mark for the correct option A. [1 mark for calculating the lower value of each batch correctly to get $1275]

Cost on 1 Jan 2021 = $12 000
Depreciation for year 2021 = 20% * $12 000 = $2400
Net book value (NBV) on 1 Jan 2022 = $12 000 - $2400 = $9600
Depreciation for year 2022 = 20% * $9600 = $1920
NBV on 31 Dec 2022 = $9600 - $1920 = $7680
Sale proceeds on 31 Dec 2022 = $7500
Loss on disposal = NBV - Sale proceeds = $7680 - $7500 = $180 loss.

Award 1 mark for the correct option A. [1 mark for correct reducing balance calculation resulting in $180 loss]

Cost of sales = Opening inventory + Purchases - Closing inventory = $12 000 + $85 000 - $17 000 = $80 000.
Average inventory = (Opening inventory + Closing inventory) / 2 = ($12 000 + $17 000) / 2 = $14 500.
Rate of inventory turnover = Cost of sales / Average inventory = $80 000 / $14 500 = 5.517 times (which rounds to 5.52 times).

Award 1 mark for the correct option B. [1 mark for correct calculation of cost of sales, average inventory, and rate of inventory turnover]

Profit before appropriations = $48 000
Add: Interest on drawings (X: $800 + Y: $400) = $1200
Subtotal = $49 200
Less: Salary to Y = ($12 000)
Residual profit to be shared = $37 200
Y's share of residual profit (1/3 of residual profit) = 1/3 * $37 200 = $12 400.

Award 1 mark for the correct option B. [1 mark for correct calculation of residual profit and Y's 1/3 share of $12 400]

The trade payables account balance is computed as follows:
Credit Purchases = Cash paid + Discounts received + Closing trade payables - Opening trade payables
Credit Purchases = $64 300 + $1500 + $10 200 - $8500 = $67 500.

Award 1 mark for the correct option C. [1 mark for correct calculation using the trade payables account logic to arrive at $67 500]

1. Calculate the Cost of Sales:
$$\text{Cost of Sales} = \frac{\text{Revenue}}{1 + \text{Markup}} = \frac{\$150\,000}{1.25} = \$120\,000$$

2. Use the Cost of Sales formula to find Purchases:
$$\text{Cost of Sales} = \text{Opening Inventory} + \text{Purchases} - \text{Closing Inventory}$$
$$\$120\,000 = \$12\,000 + \text{Purchases} - \$15\,000$$
$$\$120\,000 = \text{Purchases} - \$3\,000$$
$$\text{Purchases} = \$123\,000$$

1 mark for the correct option D.

The factory cost of production is calculated by adding factory overheads to the prime cost, and adjusting for the change in work in progress. Delivery expenses are selling and distribution costs, and are not included in the manufacturing account.

$$\begin{aligned} \text{Factory Cost of Production} &= \text{Prime Cost} + \text{Factory Overheads} + \text{Opening WIP} - \text{Closing WIP} \\ &= \$180\,000 + \$85\,000 + \$15\,000 - \$18\,500 \\ &= \$261\,500 \end{aligned}$$

1 mark for the correct option A.

1. Calculate Interest on Capital:
- Xavier: $6\% \times $50\,000 = $3\,000$
- Yasmin: $6\% \times $30\,000 = $1\,800$
- Total Interest on Capital: $$3\,000 + \$1\,800 = \$4\,800\$

2. Deduct salary and interest from profit to find the residual profit:
$$\text{Residual Profit} = \$32\,800 - \$4\,800 \text{ (interest)} - \$8\,000 \text{ (salary)} = \$20\,000$$

3. Share the residual profit in the ratio 3 : 2:
$$\text{Yasmin's share} = \frac{2}{5} \times \$20\,000 = \$8\,000$$

4. Calculate the total amount credited to Yasmin's current account:
$$\text{Total Credited} = \text{Interest on Capital } (\$1\,800) + \text{Salary } (\$8\,000) + \text{Share of Profit } (\$8\,000) = \$17\,800$$

(a) Opening Capital (1 January 2023):
Assets: Premises $95,000 + Equipment $18,000 + Inventory $14,500 + Trade Receivables $8,200 = $135,700 [1]
Liabilities: Trade Payables $6,400 + Bank Overdraft $3,100 = $9,500 [1]
Capital = $135,700 - $9,500 = $126,200 [2]

(b) Closing Capital (31 December 2023):
Equipment: $18,000 - Depreciation ($18,000 * 10%) = $16,200 [1]
Assets: Premises $95,000 + Equipment $16,200 + Inventory $16,200 + Trade Receivables $9,600 + Bank Balance $4,200 = $141,200 [1]
Liabilities: Trade Payables $5,800 [1]

(d) 2 marks for each well-explained advantage of double-entry bookkeeping (max 4 marks). Total: 4 marks.

(a) (i) Gross margin = (Gross Profit / Revenue) * 100 = ($120,000 / $480,000) * 100 = 25.00% [3]
(ii) Profit margin = (Profit for the year / Revenue) * 100
Profit for the year = $120,000 - $72,000 = $48,000
Profit margin = ($48,000 / $480,000) * 100 = 10.00% [3]
(iii) Rate of inventory turnover = Cost of sales / Average inventory
Cost of sales = Revenue - Gross Profit = $480,000 - $120,000 = $360,000
Average inventory = ($32,000 + $38,000) / 2 = $35,000
Turnover = $360,000 / $35,000 = 10.29 times [3]
(iv) ROCE = (Profit / Capital Employed) * 100 = ($48,000 / $200,000) * 100 = 24.00% [3]
(v) Liquid ratio = (Current Assets - Inventory) / Current Liabilities
Current assets excluding inventory = Trade Receivables $44,000 + Bank $12,000 = $56,000
Current Liabilities = Trade Payables $28,000
Liquid ratio = $56,000 / $28,000 = 2.00 : 1 [3]

(b) Explanation:
- Effect on Gross Margin: Reducing selling prices will decrease the mark-up/gross profit per unit. If cost of sales remains unchanged, the gross margin will decrease. [2]
- Effect on Liquid Ratio: If sales volume increases, more cash/receivables will be generated, which are liquid assets. However, if inventory is cleared quickly, current assets excluding inventory may rise, potentially improving the liquid ratio, provided current liabilities don't increase proportionally. Alternatively, overall cash inflows from higher sales volume could boost the ratio. [3]
