General Journal's Role in Purchases Ledger Adjustments

Steps:

• Purchases ledger control account tracks total creditor balances from purchase transactions.
• General journal records adjusting and non-routine entries, including inter-ledger set-offs.
• Review options to identify entries that adjust creditor balances via journal postings.
• Contra entries qualify as they offset sales and purchases ledger balances in the journal.

Why A is correct:

• Contra entries represent mutual indebtedness between sales and purchases ledgers, recorded in the general journal per double-entry principles to debit/credit both control accounts simultaneously.

Why the others are wrong:

• B: Goods returned to suppliers are posted from the purchases returns day book directly to the purchases ledger, bypassing the general journal.
• C: Irrecoverable debts relate to debtors in the sales ledger control account, not creditors.
• D: Refunds from suppliers are typically entered in the cash book or returns day book, not the general journal.

Final answer: A
