The total cost of 500 will be divided between the products equally 250 per product. Then, it will be allocated per quantity. The inventory valuation will be look like this:
The cost per one quantity will be computed in the inventory to compute the cost price. It will look like this:
Product | Rate | Qty | By Method | Cost/Qty |
Material | 70 | 100 | 350 | 73.50 |
Finished Product | 50 | 50 | 150 | 63 |
