Accounting corrections and error handling: Detected monetary errors in the books are corrected with which kind of journal entries?

Introduction / Context:
In double-entry accounting, every transaction affects at least two accounts through debits and credits. When errors are detected—such as mispostings, omissions, or wrong amounts—accountants pass correcting journal entries. This question asks which side (debit or credit) is used for corrections.

Given Data / Assumptions:

• Books follow double-entry principles.
• Errors may require increasing or decreasing balances.
• Correcting entries restore the intended accounting effect.

Concept / Approach:
Corrections are not limited to one side. Depending on the nature of the error (overstated debit, understated credit, wrong account used), the fix may be a debit, a credit, or a combination, always keeping debits equal to credits. Hence, “both (a) and (b)” is appropriate.

Step-by-Step Solution:

Verification / Alternative check:
Accounting manuals specify that correction entries follow normal rules of debit/credit depending on account types (assets, liabilities, equity, income, expense).

Why Other Options Are Wrong:

Common Pitfalls:
Using a one-sided entry or suspense account without proper offset and documentation; every correction must balance and be auditable.

Final Answer:
both (a) and (b)
