Omitted adjustments to sales ledger control account Steps:

• Identify the recorded debit balance: $2000.
• Interest on overdue account ($40) is charged to debtors, a debit omitted, so add$40 to increase the balance.
• Discount allowed ($50) reduces debtors, a credit omitted, so subtract$50 to decrease the balance.
• Calculate corrected balance: $2000 +$40 - $50 =$1990.
• Note: $1990 not among choices, indicating ambiguity in item treatment or error.

Why the correct option is correct:

• No option matches; insufficient details on exact nature of "interest on overdue account" (charged vs. received) to confirm adjustment direction without standard assumption.

Why the others are wrong:

• A: Subtracts too much ($190), ignoring interest as debit.
• B: Subtracts far too much ($820), unrelated to given amounts.
• C: Subtracts too much ($790), unrelated to given amounts.
• D: Adds too much ($190), treating both as debits.

Final answer: Not enough information.
