Cost & Management Accounting Exam
Section A
Q.1 Centaurus Limited (CL) is engaged in the business of manufacture and supply of leather
jackets. Presently CL manufactures 30,000 jackets per month. Following information is
available for the month of August 2022:
In order to reduce the conversion cost, CL’s management is evaluating the following two
wage incentive plans:
Option 1: Introduce a piece wage system at the rate of Rs. 500 per unit. This is expected to
make workers 15% more efficient.
Option 2: Introduce a bonus of Rs. 50 per unit if a unit is completed within 90% of the
standard time. It is expected that after introduction of bonus, 70% units will be completed
within 90% of the standard time.
Required:
Evaluate the above options and advise the most beneficial option. (08)
Q.2 Saturn Limited (SL) imports raw material M-1 for manufacturing of its products. Following
data relating to M-1 has been extracted from SL’s latest records:
Required:
(a) Briefly explain the meaning of ‘Lead time’ and ‘Stock out costs’. (03)
(b) Compute the following with brief explanation of why it is necessary for SL to maintain
these levels of inventories:

Q.3 Pluto Limited (PL) manufactures a single product ZAA and operates at a normal capacity of
45,000 machine hours per annum which is 90% of its full capacity. Each unit requires one
machine hour. PL uses absorption costingmethod to manage its costs. Following information
has been extracted from PL’s prior year’s records:
Actual production 44,000 units
Under absorbed overheads Rs. 420,000
Fixed overhead absorption rate Rs. 200 per machine hour
PL has a policy of revising its fixed overhead absorption rate for each year on the basis of
prior year’s actual fixed overheads. During the current year, following events took place:
(i) There was an unexpected increase in demand of ZAA due to which PL utilized its
excess production capacity to manufacture maximum units of ZAA. Further, factory
workers were paid overtime of Rs. 1.2 million for additional hours worked during the
year.
(ii) The government announced an increase in taxes on electricity which increased PL’s
cost by Rs. 300,000.
(iii) Due to a mechanical fault there was a machine breakdown which had to be repaired at
a cost of Rs. 3 million. PL received insurance claim of Rs. 2.8 million against the
machine breakdown.
Required:
(a) For each of the above events, briefly explain whether they would independently result
in over/under absorbed overheads. (03)
(b) Compute the budgeted and actual fixed overheads of prior year and current year.
Assume that there was no other increase/decrease in fixed overheads other than those
mentioned above. (07)
Q.4 (a) List any two examples of bases for absorption of factory overheads. Also briefly discuss
how a base should be selected. (02)
(b) Venus Limited (VL) is a manufacturer of consumer goods. Below are the details related
to overheads of its production department for the year:
The management of VL has decided to replace one of its existing machines having zero
book value with a new machine which will cost Rs. 1,200,000 and has a useful life of
10 years. The machine will be available for use from the beginning of next year and is
expected to run for 2,500 hours during the next year including:
(i) 80 hours for setting up the machine; and
(ii) 110 hours for machine maintenance.
The estimated overheads for the year related to the new machine are given below:
It has also been decided that from the beginning of next year, one of the managers from
another department will be moved to the production department for monitoring the line
efficiency. The manager’s salary is Rs. 30,000 per month.
Required:
Compute the revised overhead absorption rate for the production department for the
next year. (06)
Q.5 Galaxy Limited (GL) is engaged in trading various consumer goods including Star-1 for
which demand is evenly distributed throughout the year. The present supplier of Star-1 offers
a bulk purchase discount of 5% on all orders of 20,000 units and above, which GL has been
availing. Due to availing the bulk discount, the normal transit loss has been increased from
3% to 4%.
GL is currently evaluating to adopt economic order quantity (EOQ) model which would
reduce the transit loss to 3%.
Required:
Advise GL whether it will be beneficial to adopt EOQ model. (10)
