Al Khoud Chem manufactures two industrial chemicals in a joint process. In October, OMR200,000 of direct materials were processed at a cost of OMR300,000, resulting in 16,000 pounds of product P and 4,000 pounds of product G. Product P sells for OMR35 per pound and product G sells for OMR60 per pound. Management generally processes each of these chemicals further in separable processes to manufacture more refined products. Product P is processed separately at a cost of OMR7.50 per pound, with the resulting product, P-R, selling for OMR45 per pound. Product G is processed separately at a cost of $10 per pound, and the resulting product, G-R, sells for OMR100 per pound.

(a) Compute the company's total joint production costs.

(b) Assuming that total joint production costs amounted to OMR500,000, allocate these costs by using:

1. The physical-units method.

2. The relative-sales-value method.

3. The net-realizable-value method.

(c) Does the firm's cost-of-goods-sold figure influenced by the choice of a joint-cost allocation method? Briefly explain.
