Adjusting trade payables for ledger errors Steps:

• Start with original balance of $5470.
• Add $100 for overcast discount allowed, as it understated payables by recording excess reduction.
• Subtract $350 for omitted returns outwards, as it overstated payables by not crediting the supplier.
• Subtract $150 for undercast payments, as it overstated payables by insufficiently reducing the liability.
• Calculate corrected total: $5470 +$100 - $350 -$150 = $5070.

Why D is correct:

• Control account balance is adjusted by netting error effects: + overcast discount, - omitted returns, - undercast payments, yielding $5070 per standard ledger reconciliation.

Why the others are wrong:

• A: Subtracts only returns and part of payments, ignoring discount overcast.
• B: Adds returns instead of subtracting, overstating correction.
• C: Adds all error amounts, reversing their effects on payables.

Final answer: D
