  1. 201,300\text{₦}201,300Answer
  2. B
    192,700\text{₦}192,700
  3. C
    197,000\text{₦}197,000
  4. D
    229,700\text{₦}229,700

Answer

The total cost of production transferred to the Trading Account is 201,300\text{₦}201,300.
The total cost of production is determined by summing Prime Cost and Factory Overheads, adding Opening Work-in-Progress, and deducting Closing Work-in-Progress. 145,000+52,000+18,50014,200=201,300\text{₦}145,000 + \text{₦}52,000 + \text{₦}18,500 - \text{₦}14,200 = \text{₦}201,300.

Step-by-Step Solution

1
Calculate total manufacturing costs incurred during the year
Prime Cost+Factory Overheads=145,000+52,000=197,000\text{Prime Cost} + \text{Factory Overheads} = \text{₦}145,000 + \text{₦}52,000 = \text{₦}197,000
Total cost incurred on production includes direct costs plus factory indirect expenses before adjusting for unfinished goods.
2
Adjust for Opening Work-in-Progress
197,000+18,500=215,500\text{₦}197,000 + \text{₦}18,500 = \text{₦}215,500
Opening WIP represents partially completed goods from the previous period completed during the current period, so it is added.
3
Deduct Closing Work-in-Progress
215,50014,200=201,300\text{₦}215,500 - \text{₦}14,200 = \text{₦}201,300
Closing WIP represents goods remaining uncompleted at year-end, which must be deducted to find the cost of fully finished goods.
