The company sells its products through its own stores and other outlets. Total fixed expenses are Br15,000,000 per month. Variable expenses and monthly sales data are given below:

                                                        LCD                 CRT

Variable expenses                         Br5,000           Br2,000

Monthly sales in units                     2,000               3,000

Required: (unless stated figures should be computed for one month)

a) Determine breakeven total volume of sales and sales volume for each product.

b) Determine sales volume and sales revenue for the company to earn Br500,000 profit after 30% profit tax.

c) The company has planned to incur Br 200,000 monthly selling (promotional) expenses to increase sales volume for its LCD TV sets to 4,000. If the plan materializes and other things remain constant, determine breakeven sales volume and sales revenue for the company.

d) The company has planned to buy new and improved technology that reduces variable production expenses for its LCD TV set to Br4,000 while increasing its monthly fixed production costs by Br500,000. If the plan materializes and other things remain constant, determine breakeven sales volume and sales revenue for the company.

e) If the company is guaranteed with total sales volume of 10,000 TV sets in a given month, should it go for option "c" or "d" above given that sales mix remained constant as provided in each of the two options? Why? What if the guaranteed total sales volume of 7,000 instead of 10,000? Why? What should be the guaranteed total sales volume for the two options to provide equal profit to the company?

Question 2. Sino-woodworks Ethiopia Ltd makes office furniture from fine hardwoods. The company uses a job-order costing system and predetermined overhead rates to apply manufacturing overhead cost to jobs.

At the beginning of the year, the company's management made the following estimates for the year:


Preparation Fabrication
Machine-hours  80,000 21,000
Direct labor-hours  35,000 65,000
Direct materials cost  $190,000 $400,000
Direct labor cost  $280,000 $530,000
Manufacturing overhead cost  $416,000 $720,000

Job-C was started on April 1 and completed on May 12. The company's cost records show the following information concerning the job:


Preparation Fabrication
Machine-hours   350 70
Direct labor-hours  80 130
Direct materials cost  $940 $1,200
Direct labor cost   $710 $980


a) Compute the predetermined overhead rate used during the year in the Preparation and Fabrication Departments.

b) Compute the total overhead cost applied to Job-C.

c) What would be the total cost recorded for Job-C? If the job contained 25 units, what would be the unit product cost?

d) At the end of the year, the records of the company revealed the following actual cost and operating data for all jobs worked on during the year:


Preparation Fabrication
Machine-hours   73,000 24,000
Direct labor-hours   30,000 68,000
Direct materials cost   $165,000 $420,000
Manufacturing overhead cost   $390,000 $740,000
