  2. B
    ₦675,000
  3. C
    ₦385,000
  4. D
    ₦495,000

Answer

The total factory overhead cost to be charged to the Manufacturing Account is ₦375,000.
Factory overheads include all indirect costs relating to manufacturing activities. In this scenario, the supervisor's salary (₦180,000), adjusted power and fuel (₦95,000 less ₦15,000 prepaid = ₦80,000), factory machinery depreciation (₦65,000), and adjusted factory rates and insurance (₦40,000 plus ₦10,000 accrued = ₦50,000) are summed to give ₦375,000. Direct wages belong in prime cost, and office salaries belong in the profit and loss account.

Step-by-Step Solution

1
Identify and adjust factory indirect expenses
Factory power and fuel = ₦95,000 - ₦15,000 (prepaid) = ₦80,000; Factory rates and insurance = ₦40,000 + ₦10,000 (accrued) = ₦50,000.
Prepaid expenses must be deducted from paid amounts, whereas accrued expenses must be added to reflect the actual expense incurred for the accounting period.
2
Filter for factory overhead costs only
Factory supervisor's salary (₦180,000), Adjusted factory power (₦80,000), Depreciation of factory machinery (₦65,000), and Adjusted factory rates (₦50,000).
Direct wages (₦300,000) belong to Prime Cost, and Office administrative salaries (₦120,000) are non-factory operating expenses.
3
Calculate total factory overheads
₦180,000 + ₦80,000 + ₦65,000 + ₦50,000 = ₦375,000.
Summing all adjusted indirect manufacturing expenditures yields the total factory overhead.

Key Concept

Factory overheads consist of all indirect production costs incurred inside the factory, adjusted for accruals and prepayments, excluding direct costs (prime cost) and administrative/selling expenses.
