Problem 1: The following costs were incurred in March:

Direct materials P39,000

Direct labor P24,000

Manufacturing overhead P14,000

Selling expenses P11,000

Administrative expenses P19,000

Required: Compute the:

1. Total prime costs during the month.
2. Total conversion costs during the month.

Problem 2: Adelaide Company's manufacturing overhead is 20% of its total conversion costs. If direct labor is P45,000 and if direct materials are P53,000, how much is the manufacturing overhead amount?

Problem 3: The Work in Process inventory account of a manufacturing company shows a balance of P18,000 at the end of an accounting period. The job cost sheets of the two uncompleted jobs show charges of P6,000 and P3,000 for materials, and charges of P4,000 and P2,000 for direct labor. From this information, it appears that the company is using a predetermined overhead rate, as a percentage of direct labor costs. At what percentage is the predetermined overhead rate?

Problem 4: ORB Manufacturing Company uses a job order cost system. At the beginning of February, ORB only had one job in process, Job #594. The direct costs assigned to this job at that time were P800 of materials and P650 of labor. Job #594 was finished during February incurring additional direct costs of P120 for materials and P370 for labor. Job #595 were started and finished during February. The direct costs assigned to this job were P310 for materials and P190 for labor. Job #596 was started during February but was not finished by the end of the month. The direct costs assigned to this job were P740 for materials and P300 for labor. ORB applies manufacturing overhead to its products at a rate of 200% of direct labor cost. Determine ORB's cost of goods manufactured for February.

Problem 5: Turner Company uses the weighted-average method in its process costing system. The first processing department, the Welding Department, started the month with 13,000 units in its beginning work in process inventory that were 80% complete with respect to conversion costs. The conversion cost in this beginning work in process inventory was P23,920. An additional 66,000 units were started into production during the month and 68,000 units were completed in the Welding Department and transferred to the next processing department. There were 11,000 units in the ending work in process inventory of the Welding Department that were 30% complete with respect to conversion costs. A total of P127,890 in conversion costs were incurred in the department during the month.

Required:

1. Compute the equivalent units for the conversion costs.
2. Calculate the cost per equivalent unit for conversion costs for the month. (Round off to three decimal places.)
3. Using the FIFO costing method, compute the:
   1. Equivalent units for the conversion costs
   2. Cost per equivalent unit for the conversion costs.
