Cevap
The prime cost of production is ₦835,000.
Prime cost is the total of all direct production costs. First, calculate the cost of raw materials consumed: Opening Stock (₦150,000) + Purchases (₦420,000) + Carriage Inwards (₦30,000) - Closing Stock (₦90,000) = ₦510,000. Next, add all other direct costs, which are Direct Factory Wages (₦280,000) and Production Royalties (₦45,000). ₦510,000 + ₦280,000 + ₦45,000 gives ₦835,000. Indirect costs such as factory supervisor salary, factory rent, and plant depreciation are factory overheads and are excluded from prime cost.
