What record-keeping practice is recommended to prepare an accurate trading and profit and loss account?

• A. Rely mainly on estimates and a simplified ledger.
• B. Maintain only a cash book with no ledgers.
• C. Keep a detailed cash book and general ledger supported by subsidiary day books.
• D. Use a single trial balance with no supporting documents.

Answer: (C)

The key idea here is that an accurate trading and profit and loss account comes from complete, verifiable records that capture every transaction, not just cash movements. A detailed cash book records all cash receipts and payments, while the general ledger holds the balances of every account after those transactions are posted. Subsidiary day books—such as sales, purchases, returns, and petty cash—provide a clear, itemised trail of individual transactions that feed into the ledgers. With these sources, you can correctly determine revenue, cost of goods sold, and expenses, and then calculate gross and net profit. This structure also creates a solid audit trail and makes it easier to prepare a trial balance, which then underpins the trading and profit and loss figures. Relying on estimates and a simplified ledger risks misstatement because it may omit or obscure transactions. Having only a cash book with no ledgers fails to capture non-cash items and credit activity, leading to an incomplete picture. A single trial balance with no supporting documents lacks evidence for each figure and makes it hard to verify accuracy.
