Answer

The Prime Cost of Kano Garment Manufacturing Enterprise for the year ended 31 December 2025 is ₦340,000.
Prime cost represents the total sum of all direct costs associated with production. It is calculated as: Prime Cost = Cost of Raw Materials Consumed + Direct Labour + Direct Expenses. Here, Cost of Raw Materials Consumed = Opening Stock (₦45,000) + Purchases (₦185,000) + Carriage Inwards (₦12,000) - Returns Outwards (₦8,000) - Closing Stock (₦34,000) = ₦200,000. Adding Direct Factory Labour (₦115,000) and Direct Royalties (₦25,000) gives a Prime Cost of ₦340,000.

Step-by-Step Solution

1
Calculate Cost of Raw Materials Consumed
₦200,000
Formula: Opening Inventory of Raw Materials (₦45,000) + Purchases (₦185,000) + Carriage Inwards (₦12,000) - Returns Outwards (₦8,000) - Closing Inventory of Raw Materials (₦34,000) = ₦200,000.
2
Identify Direct Labour and Direct Expenses
Direct Labour = ₦115,000; Direct Expenses (Royalties) = ₦25,000
Direct labour wages and production royalties are directly traceable to individual units of production.
3
Compute Total Prime Cost
₦340,000
Prime Cost = Raw Materials Consumed (₦200,000) + Direct Labour Wages (₦115,000) + Royalties (₦25,000) = ₦340,000.
