Cevap

Royalty paid per unit of item produced matches with direct expense in Prime Cost; Factory supervisor's salary and plant depreciation matches with indirect manufacturing costs under Factory Overheads; Net decrease in Work-in-Progress matches with being added to Prime Cost and Factory Overheads; Carriage inwards on raw materials matches with being added to direct materials cost to find cost of raw materials consumed.
Each item is correctly matched according to standard cost accounting rules for manufacturing accounts: Carriage inwards adds to raw materials cost, royalties form part of direct expenses within Prime Cost, supervisory salaries and plant depreciation are factory overheads, and a net decrease in WIP increases the overall cost of production.

Adım Adım Çözüm

1
Classify direct costs
Identify that raw material carriage inwards increases the raw material purchase cost, while unit-based production royalties are direct expenses forming part of Prime Cost.
Direct costs are expenses directly traceable to the unit of output.
2
Classify indirect costs
Group factory supervisor salaries and plant depreciation into Factory Overheads.
Indirect manufacturing costs support production but cannot be assigned directly to individual units.
3
Apply Work-in-Progress adjustment rules
Determine that a net decrease in WIP (Opening WIP>Closing WIPOpening\ WIP > Closing\ WIP) represents additional cost absorbed during the period, thereby increasing the Cost of Production.
Cost of Production = Prime Cost + Factory Overheads + Opening WIP - Closing WIP.

What is the total cost of production for the year?

Cevabı ve açıklamayı göster

Cevap: ₦920,000

Cevap

The total cost of production for the year is ₦920,000.
The correct total cost of production is derived by first adding direct materials (₦450,000), direct wages (₦220,000), and direct expenses (₦80,000) to find Prime Cost of ₦750,000. Adding factory overheads (₦150,000) gives ₦900,000. Adjusting for work-in-progress (+ ₦60,000 opening WIP - ₦40,000 closing WIP) yields ₦920,000.

Adım Adım Çözüm

1
Calculate Prime Cost
Prime Cost = Direct Materials (₦450,000) + Direct Wages (₦220,000) + Direct Expenses (₦80,000) = ₦750,000
Prime cost comprises all direct manufacturing expenditures.
2
Add Factory Overheads to Prime Cost
Total Factory Overhead Cost = ₦750,000 + ₦150,000 = ₦900,000
Factory overheads represent indirect factory operational expenses.
3
Adjust for Opening and Closing Work-in-Progress
Cost of Production = ₦900,000 + Opening WIP (₦60,000) - Closing WIP (₦40,000) = ₦920,000
Opening work-in-progress is added to current production expenditures while uncompleted closing work-in-progress is deducted.

Adım Adım Çözüm

1
Determine the formula for Cost of Production
Prime Cost + Factory Overheads + Opening Work-in-Progress - Closing Work-in-Progress = Cost of Production
The cost of completed production requires combining prime costs with indirect factory expenses and adjusting for incomplete goods at the start and end of the period.
2
Identify the elements constituting Prime Cost
Raw Materials Consumed + Direct Wages + Royalties / Direct Production Expenses = Prime Cost
Prime cost is strictly the sum of directly traceable manufacturing costs.
3
Categorize indirect factory costs
Factory Building Rent + Plant Depreciation + Factory Supervisor's Salary = Factory Overheads
Expenses necessary to maintain factory operations that cannot be directly traced to individual products are classified as factory overheads.
4
Calculate Manufacturing Profit
Market Value of Finished Goods Produced - Cost of Production = Manufacturing Profit
When a firm transfers finished goods at market value, the differential over actual production cost measures the profitability of the manufacturing operation.

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.

Adım Adım Çözüm

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

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

Cevap: 385000

Cevap

The total cost of production for the year is ₦385,000.
The correct cost of production is computed by combining raw materials consumed (₦205,000), direct wages (₦120,000), and factory overheads (₦65,000) to arrive at manufacturing costs before WIP adjustments (₦390,000), then adding opening work-in-progress (₦18,000) and deducting closing work-in-progress (₦23,000), yielding exactly ₦385,000.

Adım Adım Çözüm

1
Determine the cost of raw materials consumed
Raw Materials Consumed = ₦45,000 + ₦180,000 + ₦15,000 - ₦35,000 = ₦205,000
Carriage inwards is added to raw materials purchases while closing stock of raw materials is subtracted from total materials available for use.
2
Calculate the Prime Cost
Prime Cost = Direct Materials Consumed (₦205,000) + Direct Factory Wages (₦120,000) = ₦325,000
Prime Cost consists of all direct manufacturing costs including direct raw materials and direct labor.
3
Determine Total Factory Overheads
Factory Overheads = Factory Power and Fuel (₦40,000) + Depreciation of Factory Equipment (₦25,000) = ₦65,000
Factory overheads encompass all indirect expenses incurred within the factory environment.
4
Adjust Prime Cost and Overheads for Work-in-Progress (WIP) to obtain Cost of Production
Cost of Production = Prime Cost (₦325,000) + Factory Overheads (₦65,000) + Opening WIP (₦18,000) - Closing WIP (₦23,000) = ₦385,000
Opening WIP is added because it represents partially finished goods completed in the current period, while closing WIP is deducted because it remains incomplete at year end.

Cevap: 416000

Cevap

The Cost of Production for the year is ₦416,000.
The Cost of Production is ₦416,000. It is derived by first calculating Raw Materials Consumed (₦45,000 + ₦180,000 + ₦12,000 - ₦35,000 = ₦202,000). Adding Direct Labor inclusive of accruals (₦90,000 + ₦5,000 = ₦95,000) and Direct Expenses (₦28,000) yields a Prime Cost of ₦325,000. Adding total Factory Overheads (₦40,000 + ₦35,000 + ₦22,000 = ₦97,000) gives total factory costs of ₦422,000. Finally, adjusting for Work-in-Progress (+ ₦18,000 Opening WIP - ₦24,000 Closing WIP) gives ₦416,000.

Cevap: ₦520,000

Cevap

The total Cost of Production for the year is ₦520,000.
The total Cost of Production of ₦520,000 is correctly calculated by summing the Prime Cost (₦400,000), Factory Overheads (₦100,000), and Opening Work-in-Progress (₦35,000), then subtracting Closing Work-in-Progress (₦15,000).

Adım Adım Çözüm

1
Calculate Cost of Raw Materials Consumed
��50,000 + ₦200,000 + ₦10,000 - ₦40,000 = ₦220,000
Carriage inwards is added to raw material purchases while closing raw material inventory is deducted.
2
Calculate Prime Cost
₦220,000 (Raw Materials) + ₦150,000 (Direct Wages) + ₦30,000 (Direct Expenses) = ₦400,000
Prime cost is the sum of all direct costs of production.
3
Calculate Total Factory Overheads
₦60,000 (Factory Rent) + ₦40,000 (Depreciation) = ₦100,000
Factory overheads consist of all indirect manufacturing expenses incurred in the factory.
4
Calculate Cost of Production
₦400,000 (Prime Cost) + ₦100,000 (Factory Overheads) + ₦35,000 (Opening WIP) - ₦15,000 (Closing WIP) = ₦520,000
Cost of production is obtained by adding factory overheads and opening work-in-progress to prime cost, and deducting closing work-in-progress.

Cevap

Cost of Raw Materials Consumed matches Opening Stock of Raw Materials + Purchases + Carriage Inwards - Closing Stock of Raw Materials; Prime Cost matches Cost of Raw Materials Consumed + Direct Wages + Direct Factory Expenses; Factory Overheads matches Indirect Factory Wages + Factory Rent + Factory Machinery Depreciation + Indirect Materials; Cost of Production matches Prime Cost + Factory Overheads + Opening Work-in-Progress - Closing Work-in-Progress.
Each manufacturing accounting term is correctly paired with its defining formula. Raw materials consumed aggregates direct raw material movements. Prime cost sums all direct inputs. Factory overheads accumulate indirect factory costs. Cost of production incorporates prime cost, factory overheads, and work-in-progress adjustments.

Adım Adım Çözüm

1
Identify the formula for Direct Materials Consumed
Opening stock of raw materials plus purchases plus carriage inwards minus closing stock of raw materials.
Carriage inwards adds to the cost of raw material acquisition, while closing inventory is subtracted to determine net raw material used in production.
2
Determine Prime Cost composition
Sum of all direct costs (Direct Raw Materials + Direct Wages + Direct Expenses).
Prime Cost includes only direct costs traceable directly to units produced.
3
Identify Factory Overheads
Aggregation of indirect manufacturing costs such as indirect labor, factory building rent, factory power, and plant depreciation.
Overheads represent operational costs essential for factory operations but not directly assignable to specific finished goods.
4
Formulate the total Cost of Production
Prime Cost + Factory Overheads + Opening Work-in-Progress - Closing Work-in-Progress.
Cost of production measures the total cost transferred to the trading account for completed goods during the period.
