What is the ending balance for work in process? What is the ending balance for finished goods? What is the actual manufacturing overhead cost incurred during December before adjustment? What is the total applied manufacturing overhead cost during December before adjustment? What is the unadjusted cost of goods sold? Was the manufacturing overhead for the month of December overapplied/underapplied ? What is the amount of Manufacturing overhead overapplied/underapplied? What is the adjusted cost of goods sold? What is gross margin? What is the total prime cost for Job#1? What is the total conversion cost for job #1? What is the total product cost for job#1? What was the period cost incurred for the month of December?   What is the total variable cost incurred for Job #1(assume that all selling and administrative cost and all manufacturing overhead costs are fixed.)? What is the contribution margin for Job #1 (assume that all selling and administrative cost and all manufacturing overhead costs are fixed.)? What would be the actual (not applied) total fixed manufacturing overhead cost incurred for the company for the month if the order in Job #1 is for five tables instead of one table assuming this cost is with in the relevant range?

Answer 1

1.Ending Balance of Raw material is : 10400 dr

2.Ending Balance of work in progress is :

Job 1 : nil

Job 2 : 5990 dr

3.Ending Balance of Finished goods is : zero or nil.

4.Actual manufacturing OH cost incurred : 3000+ 500+ 150 = 3650

5.TotalApplied Manufacturing OH cost before Adjustment : 1800+900= 2700

6. Unadjusted cost of goods sold : 6580 i.e cost of manufacture as there is no opening and closing inventory.

7. Underapplied

8. Underapplied amount : 950

9.Adjusted cost of goods sold is 950 the underapplied overheads.

10.Gross margin : 25000- 6580-950/ 25000*100 = 69%

11.Total prime cost of job 1 : 4600+180 = 4780

12.conversion cost for job 1: 1800

13. Total product cost for job 1 : 6580

14. Period cost in this question includes depreciation & advertisong expenses. 600 + 1400 = 2000

15.Total variable cost incurred for job 1 = 4780 prime cost

16.here, we have no basis in the problem to allocate fixed and variable cost. So, we shall allocate costs on the basis of their absorption ratio i.e 1800:900 = 2:1.

Therefore, total maunfacturing oh = 3650incurred for job 1 it turns to be 2433. Now, net income + fixed cost = contribution = 2433+13470 ( as job 2 is still in process we assume all profit from job 1) = 15903. Contribution margin = 15903/25000*100= 63%

17. Actual total fixed manufacturing cost would be : would be for 5 tables : 5*2433 = 12165.
