1. Double Entry and Trial Balance | 复式记账与试算平衡

The mock question required recording four transactions for a sole trader: purchased goods on credit $2,000; sold goods for cash $500; paid rent $300 by cheque; received $200 from a debtor. Opening balances were: Cash $1,000, Bank $2,000, Trade receivables $200, Capital $3,200. The task was to post to ledger accounts and extract a trial balance.

模拟题要求记录个体经营者的四笔交易：赊购商品 $2,000；现金销售 $500；以支票支付租金 $300；收到债务人 $200。期初余额为：现金 $1,000、银行存款 $2,000、应收账款 $200、资本 $3,200。需要过入分类账并编制试算平衡表。

For transaction 1, purchase of goods on credit increases purchases (debit) and creates a liability (credit trade payables). Debit Purchases $2,000, Credit Trade payables $2,000. No cash is involved, so cash and bank are unaffected.

交易 1：赊购商品增加购货（借记）并产生负债（贷记应付账款）。借记购货 $2,000，贷记应付账款 $2,000。不涉及现金，因此现金和银行存款不受影响。

Transaction 2, cash sale, increases cash and revenue. Debit Cash $500, Credit Sales $500. The cash account rises by the amount received.

交易 2：现金销售增加现金和收入。借记现金 $500，贷记销售收入 $500。现金账户增加相应金额。

Transaction 3, paying rent by cheque, reduces the bank balance and records an expense. Debit Rent expense $300, Credit Bank $300. The bank account is credited because money leaves the business.

交易 3：以支票支付租金减少银行存款并记录费用。借记租金费用 $300，贷记银行存款 $300。银行存款账户因资金流出企业而贷记。

Transaction 4, receiving cash from a debtor, increases cash and reduces the amount owed by customers. Debit Cash $200, Credit Trade receivables $200. After this, the trade receivables balance falls to zero.

交易 4：收到债务人现金增加现金并减少应收账款。借记现金 $200，贷记应收账款 $200。此后应收账款余额降至零。

After posting, the trial balance totals are equal. Debit column: Purchases $2,000, Cash $1,700 (1,000 + 500 + 200), Bank $1,700 (2,000 – 300), Rent $300, total $5,700. Credit column: Sales $500, Trade payables $2,000, Capital $3,200, total $5,700. The agreement confirms correct double entry.

过账后试算平衡表总额相等。借方栏：购货 $2,000、现金 $1,700（1,000 + 500 + 200）、银行存款 $1,700（2,000 − 300）、租金 $300，合计 $5,700。贷方栏：销售收入 $500、应付账款 $2,000、资本 $3,200，合计 $5,700。两者相符，证明复式记账正确。

2. Accruals and Prepayments Adjustments | 应计与预付款调整

The question stated that at the year end, rent prepaid amounted to $400 and wages accrued were $250. Students had to show the adjusting entries and explain the effect on profit and financial position.

题目说明年末预付租金为 $400，应计工资为 $250。考生需列示调整分录并解释对利润和财务状况的影响。

Rent prepaid means the business has paid for a future period. The adjustment reduces the rent expense and recognises a current asset. Entry: Debit Prepaid rent $400, Credit Rent expense $400. Profit increases because expenses are lower.

预付租金意味着企业已支付未来期间的费用。调整减少了租金费用并确认一项流动资产。分录：借记预付租金 $400，贷记租金费用 $400。利润因费用减少而增加。

Wages accrued are an expense incurred but not yet paid. The liability must be recorded. Entry: Debit Wages expense $250, Credit Accrued wages $250. Profit decreases as expenses rise. The statement of financial position will show prepaid rent under current assets and accrued wages under current liabilities.

应计工资是已发生但未支付的费用。必须记录此项负债。分录：借记工资费用 $250，贷记应计工资 $250。利润因费用增加而减少。财务状况表中预付租金列于流动资产下，应计工资列于流动负债下。

3. Depreciation Methods | 折旧方法

The mock paper required calculation of annual depreciation for equipment costing $10,000 with a residual value of $1,000 and useful life of 4 years. Both straight-line and reducing balance (25% per annum) methods had to be applied for the first year, with the journal entry recorded.

模拟卷要求计算设备成本 $10,000、残值 $1,000、使用年限 4 年的年折旧额。需分别采用直线法和余额递减法（年折旧率 25%）计算第一年折旧，并记录会计分录。

Straight-line method: (Cost – Residual value) / Useful life = ($10,000 – $1,000) / 4 = $2,250 per year. The depreciation charge is constant over the asset’s life.

直线法：（成本 − 残值）/ 使用年限 = ($10,000 − $1,000) / 4 = $2,250 每年。折旧费用在资产寿命内保持不变。

Reducing balance method: Year 1 depreciation = 25% × $10,000 = $2,500. This method applies a fixed percentage to the carrying amount, producing a higher charge in early years.

余额递减法：第一年折旧 = 25% × $10,000 = $2,500。该方法对账面净值使用固定百分比，在早期产生较高费用。

The journal entry is identical in form regardless of method: Debit Depreciation expense (income statement) with the calculated amount, Credit Accumulated depreciation (statement of financial position). This reduces the carrying amount of the asset.

无论采用哪种方法，会计分录形式相同：借记折旧费用（利润表）计算出的金额，贷记累计折旧（财务状况表）。这降低了资产的账面净值。

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

The scenario gave trade receivables at year end of $8,000. A specific debt of $300 was considered irrecoverable and must be written off. The provision for doubtful debts was to be adjusted to 5% of remaining receivables. The opening provision stood at $350.

题目情景：年末应收账款为 $8,000。一笔 $300 的债务被认为无法收回，需注销。坏账准备应调整为剩余应收账款的 5%。期初准备余额为 $350。

Write off the bad debt first: Debit Bad debts $300, Credit Trade receivables $300. This removes the specific customer balance and recognises an expense.

先注销坏账：借记坏账 $300，贷记应收账款 $300。这将移除特定客户余额并确认费用。

Remaining trade receivables = $8,000 – $300 = $7,700. Required provision = 5% × $7,700 = $385. Since the existing provision is $350, an increase of $35 is needed. The entry is: Debit Increase in provision for doubtful debts (expense) $35, Credit Provision for doubtful debts $35.

剩余应收账款 = $8,000 − $300 = $7,700。所需准备 = 5% × $7,700 = $385。因现有准备为 $350，需增加 $35。分录为：借记坏账准备增加（费用）$35，贷记坏账准备 $35。

Total charge to the income statement for receivables-related expenses: Bad debts $300 + Increase in provision $35 = $335. The provision account now shows a credit balance of $385, which is deducted from trade receivables in the statement of financial position.

利润表中与应收账款相关的费用合计：坏账 $300 + 准备增加 $35 = $335。准备账户现显示贷方余额 $385，在财务状况表中从应收账款中扣除。

5. Bank Reconciliation | 银行对账

The question provided a cash book bank balance of $1,200 (debit) and a bank statement balance of $1,450. The differences were: unpresented cheques totalling $500, bank charges of $50 not yet entered in the cash book, and a deposit in transit of $200. A bank reconciliation statement was required.

题目给出了现金簿银行存款余额 $1,200（借方）和银行对账单余额 $1,450。差异包括：未兑现支票合计 $500、银行手续费 $50 尚未记入现金簿，以及一笔在途存款 $200。要求编制银行余额调节表。

First, update the cash book for items discovered from the bank statement. Deduct bank charges: Debit Bank charges $50, Credit Bank $50. The adjusted cash book balance becomes $1,200 – $50 = $1,150.

首先，根据银行对账单发现的项目更新现金簿。减去银行手续费：借记银行手续费 $50，贷记银行存款 $50。调整后现金簿余额为 $1,200 − $50 = $1,150。

Now prepare the bank reconciliation statement starting from the bank statement balance. Add the deposit in transit ($200) and subtract unpresented cheques ($500). Calculation: $1,450 + $200 – $500 = $1,150. This matches the adjusted cash book balance, confirming accuracy.

现在从银行对账单余额开始编制银行余额调节表。加上在途存款 $200，减去未兑现支票 $500。计算：$1,450 + $200 − $500 = $1,150。这与调整后现金簿余额一致，确认准确无误。

6. Control Account Reconciliations | 控制账户对账

The sales ledger control account had a balance of $4,000, while the list of individual trade receivable balances totalled $4,300. Three errors were discovered: (1) a credit note for $50 issued to a customer was entered in the returns inwards book but not posted to the customer’s personal account; (2) an irrecoverable debt of $200 written off was recorded in the general ledger but omitted from the control account; (3) a contra entry of $150 to the purchases ledger was completely omitted from the sales ledger control account. Additionally, sales had been understated in the control account by $600.

销售分类账控制账户余额为 $4,000，而明细应收账款余额合计为 $4,300。发现三处错误：（1）开给客户的一张 $50 贷项通知单已记入销售退回簿，但未过入客户明细账；（2）一笔 $200 的坏账注销已在总账中记录，但控制账户遗漏；（3）一笔与采购分类账对冲的 $150 抵消分录完全未记入销售分类账控制账户。此外，控制账户中的销售收入少记了 $600。

Correct the control account: Start with $4,000, add the omitted sales $600 (debit) → $4,600. Then deduct the bad debt written off $200 (credit) → $4,400, and deduct the contra $150 (credit) → $4,250. The corrected control account balance is $4,250.

更正控制账户：从 $4,000 开始，加上
