Questions & Answers

1) Distractor check: A student could mistakenly choose the tax period or the debtor settlement window because 'period' sounds related to deadlines, but financial reporting has a specific scope. 2) Reasoning to the answer: The accounting period represents the time span, typically one year, covered by financial statements like the balance sheet or income statement, reflecting a business’s financial performance and position. 3) Common mistake: Confusing internal financial reporting cycles with tax payment timelines.

1) Distractor check: Learners might select adjusting for revenue or passing entries, missing the specific theoretical principle that links earned income with corresponding outlays. 2) Reasoning to the answer: The matching concept ensures revenues are recognized when earned and expenses when incurred, aligning them with the period they relate to, regardless of cash flow timing. 3) Common mistake: Confusing cash receipt timing with the theoretical matching of revenues and expenses.

1) Distractor check: One might incorrectly choose consistency or materiality, confusing standard asset valuation guidelines with prudence. 2) Reasoning to the answer: The conservatism convention requires that profits be recognized only when realized, while potential losses are accounted for immediately to avoid overstating financial health. 3) Common mistake: Anticipating future gains prematurely instead of adhering to the rule of accounting caution.

1) Distractor check: A student might guess potential tax payments or staff retrenchment, assuming accounting data deals with government filings or internal human resources. 2) Reasoning to the answer: Investors and creditors analyze accounting information to forecast future cash flows, assessing the company’s ability to generate returns or meet debt obligations. 3) Common mistake: Misinterpreting external financial statements as tools for internal labor forecasting.

1) Distractor check: A candidate might mistakenly debit the purchases account instead of the generator, treating a capital asset purchase like regular trading stock. 2) Reasoning to the answer: Purchasing a generator, which is a fixed asset, requires debiting the generator account to increase the asset and crediting the cash account to reflect the payment. 3) Common mistake: Treating the acquisition of fixed capital assets as ordinary inventory purchases.

1) Distractor check: Students could mistakenly expense the labor as normal business wages and salaries, failing to recognize capital expenditure rules. 2) Reasoning to the answer: Labour costs for installing a fixed asset are capitalized as part of the asset’s cost, treated as an additional cost to the asset, increasing its recorded value. 3) Common mistake: Treating asset installation outlays as routine operating expenses.

1) Distractor check: An unwary learner might select asset versus liability rules, missing the broader universal principle governing all ledger accounts. 2) Reasoning to the answer: The cardinal rule of double-entry bookkeeping is to debit the account that receives value and credit the account that gives value, ensuring balanced entries. 3) Common mistake: Applying specific account type rules instead of the fundamental receiving and giving principle.

1) Distractor check: A student might choose an error of commission, assuming any misplaced ledger entry falls under that category. 2) Reasoning to the answer: Debiting office expenses instead of the freezer (asset) account is an error of principle, as it incorrectly treats a capital expenditure as a revenue expense. 3) Common mistake: Failing to distinguish between a technical clerical mistake and a violation of fundamental accounting principles.

1) Distractor check: Candidates might think the folio tracks transaction particulars or credit values alone, ignoring cross-referencing utilities. 2) Reasoning to the answer: The folio number in the ledger facilitates referencing, linking ledger entries to their corresponding journal entries or source documents for tracking. 3) Common mistake: Confusing the reference column with transaction narrative descriptions.

1) Distractor check: A student might forget to add one of the incoming amounts or incorrectly subtract a transaction, leading to a mismatched figure like N15,000. 2) Reasoning to the answer: Closing balance = Opening balance (N10,000) + Cash received (N3,000) + Cash via bank (N5,000) = N18,000, assuming bank receipt is treated as cash. 3) Common mistake: Omitting the initial opening balance or missing secondary cash inputs during summation.

Students might mistakenly choose option D, thinking that any balancing tool is meant for trials where totals already match, or pick option A believing it handles large discrepancies. A suspense account acts as a temporary holding facility for unallocated figures, keeping the books equal while you investigate, meaning it is specifically utilized when the precise item involved is unknown. Common mistake: Confusing a suspense account with an error correction method that changes account totals without balancing trials.

Students may select option B, assuming that because discounts are handled within cashbooks they must strictly be cash values, or option D because of bank procedures. Cashbook discount columns are periodically totaled and carried to the discount account because discounts allowed or received are kept separate from the main double-entry network until grouped at period end. Common mistake: Forgetting that discount columns are analytical aids rather than direct ledger accounts until posted.

A student might select option A or D, believing that every single expense payout requires a debit to the main petty cash account itself. The petty cash account receives a debit entry whenever the fund is set up initially, and subsequently each time it is replenished or increased to restore the established float level. Common mistake: Confusing the recording of individual voucher payments within the petty cash book with the debiting of the main petty cash account.

Students frequently choose option D (unpresented cheques), mixing up additions and subtractions relative to bank statements. Returned or dishonored cheques are subtracted from the bank statement total because such non-payments immediately diminish the available funds. Common mistake: Treating unpresented cheques and returned cheques the same way when reconciling bank balances.

A student might mistakenly choose option D, confusing the operational results of a period with overall financial position. The balance sheet acts as a financial snapshot at a specific point in time by organizing and detailing assets, liabilities, and equity. Common mistake: Confusing income statement reports of profitability with balance sheet snapshots of financial health.

Students might pick option B or D by accidentally adding carriage outwards or subtracting opening stock improperly. To find the cost of goods sold, you combine the opening stock of N10,000 with purchases of N20,000 and carriage inwards of N5,000, then subtract the closing stock of N5,000 to arrive at N30,000. Common mistake: Including carriage outwards in the cost of goods sold calculation.

A student could choose option B, mistakenly thinking net profit is evaluated inside the balance sheet. Net profit or loss for the period is calculated within the profit and loss account by subtracting both the cost of goods sold and operating expenses like carriage outwards from total sales. Common mistake: Placing expense deductions in the balance sheet instead of the profit and loss account.

Students might pick option A or C by misapplying inventory tier costs or counting the wrong purchase tranche. With total units sold reaching 300 out of 450, the remaining closing stock is 150 units; under FIFO, these remaining units come from the most recent purchase (Purchase 2 at N15), giving 150 multiplied by N15 which equals N2,250. Common mistake: Valuing ending inventory from the oldest stock layers instead of the newest when using FIFO.

A student might select option C by failing to match the right purchase tiers to the sales volume. Sales revenue equals 300 units at N20 (N6,000), while FIFO cost of goods sold comprises 100 units at N10 and 200 units at N12, totaling N3,400; subtracting this COGS from sales yields a gross profit of N2,600. Common mistake: Applying LIFO costs when the question explicitly requires the FIFO method.

Students might select option B or D by mixing up whether provision changes require debits or credits in the profit and loss account. First, find debtors after writing off N300 bad debts (N6,000 minus N300 equals N5,700), calculate the new provision at 2.5% of N5,700 which is N142.50, and compare it to the existing provision of N190 to find a decrease of N47.50 (rounded to N48); this requires a debit of N300 for bad debts and a debit of N48 for the provision decrease. Common mistake: Crediting a decrease in provision instead of debiting it.
