Problem - Makers Ltd is a manufacturing company that has three production departments known as Department A, B and C. The production overhead is absorbed on the basis of a percentage of direct labour cost for the factory as a whole. It has been suggested that a departmental overhead absorption rate would result in more accurate job costs.
Below are the budgeted and actual data for the year ended 31' October, 2008.

a) Calculate the overhead absorption rate currently in use.
b) Calculate the departmental overhead absorption rate for each department using the following basis:
Department A - machine hours
Department B - direct labour hours
Department C - direct wages
c) Using the overhead absorption rates calculated in part (b) above, determine the total cost for job no. 567 and its selling price if a profit margin is to be maintained at 20% of the selling price.
d) Show the over/under absorption of production overheads for each department using:
i. the OAR calculated in part (a) above
ii. the OAR calculated in part (b) above
