Final answer:
The efficiency of recording business transactions can be improved by using prenumbered source documents, specialized journals, posting references, and subsidiary ledgers.
Step-by-step explanation:
The efficiency of recording numerous business transactions can be best improved by the use of prenumbered source documents. These documents, such as invoices or receipts, are sequentially numbered, which helps in maintaining a systematic and organized record of transactions. By using prenumbered source documents, businesses can easily keep track of and identify each transaction.
Specialized journals, another option offered in the choices, are used to record specific types of transactions, such as sales or purchases. They can also be helpful in improving recording efficiency by providing a structured format and segregating different types of transactions.
Posting references are used to link the original transaction recorded in the journal to its corresponding entry in the general ledger. They facilitate easy retrieval of information and ensure accurate posting of transactions to the ledger.
Subsidiary ledgers, on the other hand, are supplementary records that provide detailed information about individual accounts, such as accounts receivable or accounts payable. By maintaining separate ledgers for specific accounts, businesses can improve efficiency in recording and tracking transactions.
