The Molding department bases its rate on machine-hours, and the Painting department bases its rate on direct labor-hours. At the beginning of the year, the company made the following estimates: Department Molding Painting Direct labor-hours 16,000 70,000 Machine-hours 68,000 8,000 Fixed manufacturing overhead cost Tk. 450,000 Tk. 320,000 Variable manufacturing overhead per machine-hour Tk. 4.40 Variable manufacturing overhead per labor-hour Tk. 3.60 Instructions: i. Compute the predetermined overhead rates used in the Molding Department and Painting Department. [03] ii. The job cost sheet for Job 420, which was started and completed during the year, showed the following: Department Molding Painting Direct labor-hours 12 20 Machine-hours 80 18 Direct Materials Tk. 550 Tk. 470 Direct Labor Cost Tk. 130 Tk. 260 Using the predetermined overhead rate computed in (1) above, compute the total manufacturing cost assigned to Job 420. [03] iii. What would be the total manufacturing cost recorded for Job 420? If the job contained 80 units, what would be the unit product cost? [02]
