Difficulty: HardPreparation of Manufacturing Account and Cost of Production

Match each manufacturing accounting transaction or component adjustment on the left with its correct financial treatment or resulting calculation on the right.

  • Adjustment for direct carriage on raw materials of 15,000₦15,000 and accrued direct factory wages of 25,000₦25,000Add 40,000₦40,000 in total to the basic raw materials purchased and direct labor to determine Prime Cost
  • Cost of Production calculation when factory overheads are 120,000₦120,000, opening Work-in-Progress is 35,000₦35,000, and closing Work-in-Progress is 45,000₦45,000Add a net amount of 110,000₦110,000 to Prime Cost
  • Market value transfer of finished goods when Cost of Production is ���500,000���500,000 and manufacturing profit is 20%20\% on costDebit the Trading Account with 600,000₦600,000 as cost of finished goods transferred
  • Provision for unrealized profit when closing inventory of finished goods valued at market price (25%25\% mark-up on cost) is 75,000₦75,000Set up a provision for unrealized profit of 15,000₦15,000 deducted from closing inventory on the Balance Sheet

Answer

Direct costs adjustments add 40,000₦40,000 to Prime Cost; factory overheads and Work-in-Progress net to adding 110,000₦110,000 to Prime Cost; market value transfer equals 600,000₦600,000 debited to Trading Account; and provision for unrealized profit equals 15,000₦15,000.
Each item accurately maps to its double-entry or financial statement presentation rule: direct expenses and direct labor additions increase Prime Cost; factory overheads combined with opening WIP minus closing WIP adjust Prime Cost to arrive at Cost of Production; transfer at market value includes manufacturing profit debited to Trading Account; and unrealized profit on closing inventory is isolated using the margin ratio derived from mark-up.

Step-by-Step Solution

1
Calculate Prime Cost adjustments
Direct carriage (15,000₦15,000) and accrued direct labor (25,000₦25,000) are direct expenses and direct wages respectively. Adding them gives 40,000₦40,000 added to Prime Cost components.
Direct costs form part of Prime Cost before adding overheads.
2
Calculate net overhead and Work-in-Progress adjustment to Prime Cost
Factory Overheads+Opening WIPClosing WIP=120,000+35,00045,000=110,000\text{Factory Overheads} + \text{Opening WIP} - \text{Closing WIP} = ₦120,000 + ₦35,000 - ₦45,000 = ₦110,000.
Cost of Production = Prime Cost + Factory Overheads + Opening WIP - Closing WIP.
3
Determine market value transfer of completed goods
Market Value=500,000+(0.20×500,000)=600,000\text{Market Value} = ₦500,000 + (0.20 \times ₦500,000) = ₦600,000.
Finished goods transferred at market value are debited to the Trading Account at Cost of Production plus Manufacturing Profit.
4
Calculate provision for unrealized profit on closing inventory
Margin=Mark-up100+Mark-up=25125=20%\text{Margin} = \frac{\text{Mark-up}}{100 + \text{Mark-up}} = \frac{25}{125} = 20\%. Unrealized profit=20%×75,000=15,000\text{Unrealized profit} = 20\% \times ₦75,000 = ₦15,000.
Closing inventory at market value must be reduced by the profit element to state it at actual production cost on the Balance Sheet.
