Errors Causing Sales Ledger Discrepancy

Steps:

• Identify errors that affect either individual customer accounts or the control account in the sales ledger.
• Check if error 1 impacts the total of individual balances (e.g., posting omission in subsidiary ledger).
• Check if error 2 impacts the control account balance (e.g., incorrect entry in general ledger).
• Check if error 3 causes mismatch between ledgers (e.g., arithmetic error in control account).

Not enough information: Errors 1, 2, and 3 are not specified.

Final answer: Not enough information.
