Samaki Ltd., a company based in Mombasa, exports vital fishing hooks to Madagascar.
The demand for the hooks is constant and Samaki Ltd., is able to predict the annual
demand with considerable accuracy. The predicted demand for the next couple of year is
200,000 hooks per year.
Samaki Ltd. purchases its hooks from a manufacturer in Mombasa at a price of Sh.400
per hook. In order to transport the purchases from Mombasa to Madagascar, Samaki Ltd.
must charter a ship. The charter services usually charge Sh.20,000 per trip plus Sh.40 per
hook (this includes the cost of loading the ship). The ships have a capacity of 10,000
hooks. The placing of each order including arranging for the ship requires 5 h ours of
employee time. It takes about a week for an order to arrive at the Samaki Ltd. warehouse
in Madagascar. The warehouse has a capacity of 15,000 hooks.
When a ship arrives at the Samaki warehouse, the hooks can be unloaded at a rate of 25
hooks per hour per employee. The unloading equipment used by each employee is rented
from a local supplier at a rate equivalent to Sh.100 per hour. Supervisory time for each
shipload is about 4 hours. The employees working in the warehouse have several tasks:
i Placing the hooks into storage, after they are unloaded which can be done at the
rate of about 40 per hour.
ii Checking, cleaning etc. of the hooks in inventory requires about one-half hour
per hook per year.
iii Removing a hook from inventory and preparing it for shipments to a customer
requires about one-eighth of an hour.
iv Security guards general maintenance, etc. require about 10,000 hours per year.
The average cost per hour of labour is equivalent to Sh.200 (including fringe benefits).
Samaki Ltd. has developed the following prediction equation for its general overhead
(excluding shipping materials, fringe benefits, and equipment rental):
Predicted overhead for the year = Sh.20,000,000 + (Sh.160 x Total labour hours)
The materials used to ship one hook to a customer costs Sh.20 and the delivery costs
average out to about Sh.40 per hook.
The company requires a before-tax rate of return of 20 per cent on its investment.
The ordering policy from the manufacturers by Samaki Ltd., is based on an EOQ. Model,
which is determined by the demand for hooks in Madagascar.
Required
a) Determine the quantity that should be ordered each time and the re-order level
b) If the true overhead prediction equation is:
Sh.16,000,000 + (Sh.240 x Total labour hours), what is the cost of the prediction error?

    Angels of Mercy Mission Hospital operates on charity basis. The hospital‟s board
    of directors has recently complained about the increasing size of the cost budget insisting that
    the management should cut down on costs.
    The major concern of the board is the cost of maintaining patients at the intensive care unit
    (ICU).
    The following information is available on the operations of the hospital:
    1. The average cost of maintaining a patient at the ICU per week is Shs. 200,000 compared
    to Shs. 100,000 per week incurred in maintaining a patient at the high dependency unit
    (HDU) and Shs. 50,000 per week of maintaining a patient at the general ward (GW).
    2. Past information on patients indicates that:
    (i) 50% of the patients in ICU at the beginning of the week will remain in ICU
    at the end of the week and 50% will be transferred to HDU by the end of the
    week.
    (ii) 10% of the patients in HDU at the beginning of the week will be transferred
    to ICU, 50% will remain in HDU, and 40% will be transferred to GW.
    (iii) 85% of the patients in the GW at the beginning of the week will remain in
    GW at the end of the week, 10% will be transferred to HDU and 5% to ICU.
    3. The board of directors believe that the criteria for maintaining patients in the ICU is too
    strict and should be relaxed so that only 40% of the patients in ICU at the beginning of
    the week remain there at the end of the week while 60% are transferred to HDU.
    4. The staff at the hospital insist that if the proposed criterion is adopted:
    (i) 20% of patients in HDU at the beginning of the week will be transferred to
    ICU, 50% will remain in HDU while only 30% will be transferred to GW.
    (ii) No changes will be expected in the GW.
    5. Past hospital records indicate that the hospital serves an average of 4,000 patients
    weekly.
    Required:
    (a) The steady state weekly costs under the current policy.
    (b) The steady state weekly costs under the proposed policy.
    (c) Advise the board on the best policy.
    (d) State the assumptions of the quantitative technique used in solving problems (a) and
    (b) above.

    The following information has been availed to you:
    1. Boat construction is a continuous assembling process carried out at
    the company‟s yard.
    2. Boat assembling is labour intensive involving the use of two classes of
    labour namely:
    Skilled labour at a standard rate of Shs. 1,250 per hour.
    Semi-skilled labour at a standard rate of Shs. 950 per hour.
    3. Experience on boat construction from other models indicates that the use of
    skilled labour is associated with an 80% learning curve effect whereas use of
    semi-skilled labour is associated with a 90% learning curve effect.
    4. Labour usage for the first speed boat assembled was as follows:
    Skilled labour – 952 hours.
    Semi-skilled labour – 650 hours.
    5. In October 2005, the sixth and the seventh speed boats were assembled
    from start to finish. During the month, the following labour usage and costs
    were recorded:
    Skilled labour – 680 hours at a total cost of Shs. 800,400.
    Semi-skilled labour – 1,256 hours at a total cost of Shs. 1,281,200.
    The management of Pwani Marine Ltd. is concerned about the cost variances and
    would like to learn more on the composition of the variances.
    Required:
    (i) Calculate the standard labour cost of the month of October 2005.

    0.30 kilograms of ingredient D @ Sh. 60 per Kg.
    0.20 kilograms of ingredient N @ Sh. 25 per Kg.
    The following additional information is provided:
    1. Production of 4,000 kilograms of chemical Y was budgeted for October 2004.
    2. The production of chemical Y is entirely automated and production costs attributed to
    its production comprise only direct materials and overheads.
    3. ICL‟s production process works on a just-in-time (JIT) inventory system and
    no ingredients or inventories of chemical Y are held.
    4. Overheads budgeted for the production of Y in the month of October 2004 were as
    follows:

    5. In October 2004, 4,200 kilograms of Y were produced and the cost details were as

    6. ICL‟s budget committee met recently to discuss the preparation of the cost
    control report for October 2004 and the following discussion took place:
    Chief accountant: “the overheads do not vary directly worth output and
    are therefore by definition „fixed‟. They should be analyzed and reported

    are certainly not fixed. They should be analyzed and reported on an activity based
    basis.”
    Required:
    Having regard to this discussion,

    material cost variance into price, mixture and yield components and the overhead cost
    variance into expenditure, capacity and efficiency components using consumption of
    ingredient F as the overhead absorption base).
    b) Prepare a variance analysis of the overhead production costs on Y in October 2004 on
    an activity based basis.
