1. Trial Balance and Suspense Account | 试算平衡表与暂记账户

Mock Question: A trial balance extracted from the ledger of Green Ltd shows total debits of £158,200 and total credits of £155,800. The difference has been posted to a suspense account. Investigation reveals that a cash sale of £2,400 was correctly debited to cash but was omitted from the sales account. Required: (a) State the opening suspense account balance, (b) Prepare the journal entry to correct the error, (c) Write up the suspense account.

模拟题： Green公司试算表显示借方总额£158,200，贷方总额£155,800，差额已记入暂记账户。经查，一笔现金销售£2,400已正确借记现金账户，但未贷记销售收入账户。要求：(a) 说明期初暂记账户余额，(b) 编制更正分录，(c) 开设暂记账户。

Solution: (a) The trial balance imbalance is £158,200 – £155,800 = £2,400, with debits exceeding credits. To balance, a credit of £2,400 is needed, so a suspense account with a credit balance of £2,400 must have been opened. (b) The correcting journal: Debit Suspense £2,400, Credit Sales £2,400. This eliminates the suspense credit and records the missing sales. (c) The suspense account T-account: Balance b/d (credit side) £2,400; then Correction: debit side £2,400, closing the account.

解析： (a) 试算表不平衡差额为£158,200 – £155,800 = £2,400，借方大于贷方。为配平，需贷方£2,400，因此当初开设的暂记账户必定有贷方余额£2,400。(b) 更正分录：借记暂记账户 £2,400，贷记销售收入 £2,400，从而消除暂记贷方余额并补记销售收入。(c) 暂记账户T型账：期初贷方余额£2,400；更正时借记£2,400，账户结平。

2. Accruals and Prepayments | 应计与预付费用

Mock Question: Blue Ltd’s financial year ends on 31 March. Rent of £12,000 per annum is payable quarterly in arrears. The last rent payment of £3,000 was made on 1 February for the quarter ending 31 January. Additionally, insurance premiums of £4,800 were paid on 1 July for 12 months. Calculate the amounts to be shown in the Income Statement and Statement of Financial Position for rent and insurance at 31 March.

模拟题： Blue公司会计年度截至3月31日。年租金£12,000，按季期末支付。最近一次支付£3,000在2月1日，支付截至1月31日的季度租金。此外，7月1日支付12个月保险费£4,800。计算3月31日利润表和资产负债表中租金和保险费的列示金额。

Rent: The rent expense for the year should be £12,000. As of 31 March, the period since the last payment covers 2 months (February and March) for which no payment has been made: accrued rent = £12,000 × 2/12 = £2,000. Income Statement charge = £12,000. In the Statement of Financial Position, current liabilities include an accrual of £2,000.

租金： 全年租金费用应为£12,000。截至3月31日，自上次付款后已过去2个月（2月和3月）未付租金：应计租金 = £12,000 × 2/12 = £2,000。利润表中费用列示£12,000，资产负债表中流动负债列示应计费用£2,000。

Insurance: The prepayment covers 12 months from 1 July, so by 31 March, 9 months (July to March) have been used, leaving 3 months prepaid (April to June). Prepaid amount = £4,800 × 3/12 = £1,200. Income Statement expense = £4,800 – £1,200 = £3,600. In the Statement of Financial Position, current assets include prepayment £1,200.

保险费： 预付保险覆盖7月1日起12个月，到3月31日已用9个月（7月至3月），剩余3个月预付（4月至6月）。预付金额 = £4,800 × 3/12 = £1,200。利润表费用 = £4,800 – £1,200 = £3,600。资产负债表中流动资产列示预付费用£1,200。

3. Depreciation Methods | 折旧方法

Mock Question: On 1 April, machinery was purchased for £50,000. Estimated residual value is £5,000 and useful life is 5 years. (a) Calculate annual depreciation using the straight-line method. (b) Calculate depreciation for the first 2 years using the reducing balance method at 40% per annum. (c) Prepare the journal entry to record the first year’s straight-line depreciation.

模拟题： 4月1日购入机器成本£50,000，预计残值£5,000，使用年限5年。(a) 用直线法计算年折旧额。(b) 用年折旧率40%的余额递减法计算前两年折旧。(c) 编制直线法下第一年折旧的分录。

Straight-line: (Cost – Residual value) / Useful life = (£50,000 – £5,000) ÷ 5 = £9,000 per year. Journal: Debit Depreciation Expense £9,000, Credit Accumulated Depreciation £9,000.

直线法： （成本 – 残值）/ 使用年限 = (£50,000 – £5,000) ÷ 5 = £9,000每年。分录：借记折旧费用£9,000，贷记累计折旧£9,000。

Reducing balance: Year 1 depreciation = £50,000 × 40% = £20,000. Net book value at end of Year 1 = £50,000 – £20,000 = £30,000. Year 2 depreciation = £30,000 × 40% = £12,000. Net book value end of Year 2 = £18,000. Note that residual value of £5,000 is not used in the calculation but acts as a floor.

余额递减法： 第一年折旧 = £50,000 × 40% = £20,000。第一年末账面净值 = £30,000。第二年折旧 = £30,000 × 40% = £12,000。第二年末净值为£18,000。注意残值£5,000不参与计算但作为下限。

4. Bad Debts and Allowance for Doubtful Debts | 坏账与坏账准备

Mock Question: At the year end, trade receivables total £45,000, including £3,000 owed by a customer who has been declared bankrupt. The company decides to write off this debt as bad. An allowance for doubtful debts is to be maintained at 5% of remaining receivables. The previous allowance was £1,800. Prepare the Income Statement expense and the extract from the Statement of Financial Position.

模拟题： 年末应收账款总额£45,000，其中£3,000欠款客户已宣告破产。公司决定将该笔款项核销为坏账。坏账准备按剩余应收账款的5%计提，上期准备余额为£1,800。计算利润表中坏账费用并编制资产负债表摘录。

Solution: After write-off, remaining receivables = £45,000 – £3,000 = £42,000. New allowance required = 5% × £42,000 = £2,100. Old allowance was £1,800, but since we now have a specific write-off, the allowance movement must reflect the change. Total bad debts expense in Income Statement = Bad debt written off £3,000 + Increase in allowance (£2,100 – £1,800) = £3,000 + £300 = £3,300. In SoFP, Receivables: Gross £42,000, less Allowance £2,100 = Net £39,900.

解析： 核销后剩余应收账款 = £45,000 – £3,000 = £42,000。所需新准备 = £42,000 × 5% = £2,100。原准备为£1,800，因核销需调整。利润表中坏账费用 = 已核销坏账£3,000 + 准备增加额(£2,100 – £1,800) = £3,300。资产负债表列示：应收账款总额£42,000，减坏账准备£2,100，净值£39,900。

5. Bank Reconciliation | 银行余额调节表

Mock Question: The cash book of Red Ltd shows a debit balance of £6,300 at 30 June. The bank statement shows a credit balance of £7,100. On comparison, the following are discovered: (i) Cheques totalling £1,400 issued have not yet been presented. (ii) A lodgement of £800 made on 30 June is not yet credited by the bank. (iii) Bank charges of £120 appear on the statement but not in the cash book. (iv) A direct credit from a customer of £320 is on the statement but unrecorded in the cash book. Prepare the updated cash book and the bank reconciliation statement.

模拟题： Red公司现金簿6月30日借方余额£6,300，银行对账单贷方余额£7,100。经比较发现：(i) 已开出但未兑现支票总额£1,400；(ii) 6月30日银行存款£800银行未入账；(iii) 银行手续费£120已列对账单未记现金簿；(iv) 客户直接转账£320已列对账单尚未记入现金簿。编制更新后现金簿和银行余额调节表。

Updating Cash Book: Unrecorded items: bank charges £120 (debit in cash book, reducing balance), direct credit £320 (credit in cash book, increasing balance). Adjusted cash book balance = £6,300 – £120 + £320 = £6,500 (debit).

更新现金簿： 未记录项目：银行手续费£120（借记现金簿，减少余额），直接转入£320（贷记现金簿，增加余额）。调整后现金簿余额 = £6,300 – £120 + £320 = £6,500（借方）。

Bank Reconciliation: Start with bank statement balance (credit) £7,100. Add: lodgement not yet credited £800. Less: unpresented cheques £1,400. Reconciled bank balance = £7,100 + £800 – £1,400 = £6,500. This matches the adjusted cash book balance.

银行调节表： 以银行对账单余额（贷方）£7,100为起点。加：未贷记存款£800。减：未兑现支票£1,400。调节后银行余额 = £7,100 + £800 – £1,400 = £6,500，与调整后现金簿余额一致。

6. Income Statement and Statement of Financial Position | 利润表与资产负债表

Mock Question: The following trial balance (extract) relates to Lime Ltd at 31 December: Sales £200,000; Purchases £95,000; Opening inventory £18,000; Wages £35,000; Rent £24,000; Equipment cost £80,000; Accumulated depreciation £30,000; Trade receivables £42,000; Trade payables £28,000; Cash £8,000; Capital £?. Closing inventory is £21,000. Depreciation is charged at 20% straight-line on cost. Accrued wages are £3,000. Prepare the Income Statement and Statement of Financial Position.

模拟题： Lime公司12月31日试算表摘录如下：销售收入£200,000；购货£95,000；期初存货£18,000；工资£35,000；租金£24,000；设备成本£80,000；累计折旧£30,000；应收账款£42,000；应付账款£28,000；现金£8,000；资本£?。期末存货£21,000。折旧按成本20%直线法计提。应付工资£3,000。编制利润表和资产负债表。

Income Statement for the year ended 31 December:

Sales: £200,000
Cost of sales: Opening inventory £18,000 + Purchases £95,000 – Closing inventory £21,000 = £92,000
Gross profit = £200,000 – £92,000 = £108,000
Less expenses: Wages (£35,000 + accrual £3,000) = £38,000; Rent £24,000; Depreciation (20% × £80,000) = £16,000. Total expenses = £78,000
Net profit = £108,000 – £78,000 = £30,000

截至12月31日的利润表：

销售收入：£200,000
销售成本：期初存货£18,000 + 购货£95,000 – 期末存货£21,000 = £92,000
毛利= £108,000
减：费用：工资(£35,000+应计£3,000)=£38,000；租金£24,000；折旧 (20%×£80,000)=£16,000。费用合计£78,000
净利润= £30,000

Statement of Financial Position as at 31 December:

ASSETS: Non-current assets: Equipment £80,000 – Acc. Depreciation (£30,000 + £16,000) = £34,000 net. Current assets: Inventory £21,000; Trade receivables £42,000; Cash £8,000. Total assets = £34,000 + £71,000 = £105,000.
EQUITY AND LIABILITIES: Capital (balancing figure: £105,000 – (£28,000 + £3,000) = £74,000, but must check opening capital. With net profit £30,000, we can state: Opening capital (balancing from TB) = £80,000cost + inventory18k + receivables42k + cash8k – acc dep30k – payables28k = let’s compute: TB assets: equipment80k+inventory18k+receivables42k+cash8k = 148k; TB liab + equity: payables28k+accum dep30k+ ?capital. Total credits must equal 148k, so capital = 148k – 58k = 90k. Then add net profit 30k, less drawings (none) → Closing capital £120,000? But wait, trial balance includes sales and purchases, so we already have the capital balancing figure. Let’s recompute properly: The TB provided included income and expense accounts. Total debit balances: Equipment 80k, Opening Inventory 18k, Purchases 95k, Wages 35k, Rent 24k, Receivables 42k, Cash 8k = 302k. Total credit balances: Sales 200k, Accum dep 30k, Payables 28k, capital (balancing) = 302k – 258k = 44k. So opening capital = £44,000. Then closing capital = Opening capital + Net profit = 44k +30k = 74k. Now total equity and liabilities: Capital 74k + Payables 28k + Accrual 3k = 105k. Perfect.

Non-current liabilities: None. Current liabilities: Trade payables £28,000; Accrued wages £3,000. Total equity: £74,000. Total equity and liabilities £105,000.

12月31日资产负债表：

资产：非流动资产：设备£80,000 – 累计折旧(£30,000+£16,000)=净值£34,000。流动资产：存货£21,000；应收账款£42,000；现金£8,000。资产总计£105,000。
权益与负债：期初资本£44,000（试算表平衡得出：总借方£302k – 已知贷方£258k = 资本£44k），加净利润£30,000，期末资本£74,000。流动负债：应付账款£28,000；应付工资£3,000。总权益与负债£105,000。

7. Ratio Analysis | 比率分析

Mock Question: Using the financial statements from Question 6, calculate the following ratios: (a) Gross profit margin, (b) Net profit margin, (c) Current ratio, (d) Quick ratio (inventory is the only prepayment equivalent). Comment on the liquidity position.

模拟题： 基于第6题的财务报表，计算以下比率：(a) 毛利率，(b) 净利率，(c) 流动比率，(d) 速动比率（仅存货等同于预付项目）。评述流动性状况。

Calculations:

Gross profit margin = (Gross profit / Revenue) × 100 = (£108,000 / £200,000) × 100 = 54%.
Net profit margin = (Net profit / Revenue) × 100 = (£30,000 / £200,000) × 100 = 15%.
Current ratio = Current assets / Current liabilities = (£21,000 + £42,000 + £8,000) / (£28,000 + £3,000) = £71,000 / £31,000 = 2.29 : 1.
Quick ratio = (Current assets – Inventory) / Current liabilities = (£71,000 – £21,000) / £31,000 = £50,000 / £31,000 = 1.61 : 1.

计算：

毛利率 = (毛利/收入)×100 = (£108,000/£200,000)×100 = 54%。
净利率 = (净利润/收入)×100 = (£30,000/£200,000)×100 = 15%。
流动比率 = 流动资产/流动负债 = £71,000/£31,000 = 2.29:1。
速动比率 = (流动资产-存货)/流动负债 = £50,000/£31,000 = 1.61:1。

Commentary: Both current and quick ratios are well above 1, indicating strong liquidity. The quick ratio of 1.61 suggests the company can meet its short-term obligations even without selling inventory. Profitability margins are healthy, though comparisons with industry averages would be needed for a full assessment.

评述： 流动比率和速动比率均远高于1，表明流动性强劲。速动比率1.61意味着即使不变卖存货，公司也能偿付短期债务。盈利能力指标良好，但需结合行业平均水平才能全面评估。

8. Common Mistakes and Exam Tips | 常见错误与应试技巧

Many students lose marks by confusing accruals with prepayments. Remember: an accrual increases the expense and creates a liability; a prepayment decreases the expense and creates an asset. Also, suspense accounts are only used temporarily; always ensure full double-entry corrections. When reconciling the bank, adjust the cash book first, then reconcile the bank statement.

许多考生因混淆应计与预付而丢分。记住：应计增加费用并形成负债；预付减少费用并形成资产。此外，暂记账户仅临时使用；务必保证完整的复式分录更正。调节银行账时，先调整现金簿，再调节银行对账单。

For depreciation, keep straight-line simple but do not forget to deduct accumulated depreciation from cost in the SoFP. In ratio analysis, always show the formula and your workings. Examiners reward clear layout. Use T-accounts to visualise adjustments whenever possible.

对折旧而言，直线法简单，但别忘了在资产负债表中从成本中扣减累计折旧。比率分析中，始终展示公式和计算过程。阅卷者青睐清晰的布局。尽可能借助T型账户来可视化调整。

Time management is critical in unit tests. Allocate about 1.5 minutes per mark. Practice past papers under timed conditions, and always re-read the question requirement to ensure you answer precisely what is asked.

单元测试中时间管理至关重要。大约按每题分值1.5分钟分配时间。在限定时间内练习历年试卷，并且始终重新阅读题目要求，确保回答精准切题。
