(4 marks) ii Solve the above game to determine the average winnings (or losses) each of the cousins would expect. (8 marks) (Total: 20 marks) NUMBER FOUR 1. Doha Ltd. makes special purpose equipment according to customer specifications. During the past year, one of its loyal customers, Mema Ltd., ordered a specialized equipment to be fabricated for it. Doha Ltd. Finished construction the equipment only to be notified that Mema Ltd. Had recently gone into liquidation and will not therefore take the equipment. The original price to Mema Ltd. had been agreed at Sh.9,108,000 which included an estimated normal profit mark-up of 10 per cent on total costs. The costs incurred to manufacture the machine were Sh. Direct materials 3,420,000 Direct wages 2,160,000 Overheads: Variable 540,000 Fixed; production 1,800,000 Fixed; selling and administration 360,000 8,280,000 After a sustained search, the sales manager of Doha Ltd. Has managed to locate one potential buyer, Ziwa Systems Ltd, which has indicated that it could buy the machine if certain conversion work could be carried out. Doha Ltd.s production department has made a preliminary assessment which reveals that conversion would entail extra work costed as follows: Direct materials Sh.576,000 Direct wages: Department X: 3 men for 4 weeks at Sh.27,000 per man/week Department Y: 1 man for 4 weeks at Sh.21,600 per man/week Variable overhead: 20 per cent of direct wages Fixed production overhead: Department X: 75 per cent of direct wages. Department Y: 25 per cent of direct wages. The following additional information is provided: 1. In the original machine, there were three types of basic materials: i Type P could now be sold to a scrap merchant for Sh.540,000. ii Type Q could be sold to a scrap merchant for Shs. 360,000 but it would take 120 hours of labour paid at Shs. 270 per hour to put it into a suitable condition for sale. iii Type R would need to be scrapped at a cost to Doha Ltd. of Shs.108,000 2. The materials for the conversion are at present in stock. If not needed for the conversion they could be used in the production of another machine in place of materials that would currently cost Sh.684,000. 3. The conversion would be carried out in two departments: Department X is currently extremely busy and it is estimated that its contribution overheads and profits is Sh.2.50 for every Sh.1 of labour. Department Y has idle staff, for organizational reasons its labour force cannot be reduced below its present level of four employees, all of whom are paid at the standard rate of Sh.21,600 per week. 4. The designs and specifications of the original machine could be sold in a neighbouring country for a sum of Sh.270,000 if the machine is scrapped. 5. An additional temporary supervisor would have to be engaged for the conversion work at a cost of Sh.162,000. It is the company.s normal practice to charge supervision to fixed overhead. 6. Mema Ltd. Had paid Doha Ltd. A non-returnable deposits of 12% of the selling price. Required: a) The minimum price that Doha Ltd. should accept from Ziwa Systems Ltd. for the converted machine. Explain clearly how you arrive at your figure. (16 marks) b) State clearly any assumptions that you have made in arriving at your conclusions in (a) above.

One of the company.s finished products involves two divisions; Mega and Wazo. Mega division manufactures the chassis for M101 and transfers it to Wazo division where it is reworked, fitted and assembled into the finished product. The two divisions are housed in the same building whose lease is due to expire in two years. time. Data on the operations of the two divisions for the year just ended is as follows: Mega division Quantity of units (chassis) transferred per year 30,000 Transfer price from Mega to Wazo Sh.30000 Current level of operations 75% of full capacity Loss for the year Sh.90,000,000 Wazo division Quantity of units produced and sold 30,000 Price charged outsiders Sh.150,000 Profit made for the year Sh.610,000,000 Mr. Links the general manager of Wazo division, has been considering the possibility of sourcing the chassis from outside suppliers. He has received a quotation from Bush Ltd., a competitor of Mega division offering to supply a minimum of 30,000 and a maximum of 40,000 units of chassis per year for two years with adequate guarantees as to quality and continuity of suppliers. The unit price would be Sh.22,000. Mr.Links is of the opinion that his division should be allowed to take all its requirement (30,000 units per year) of chassis from Bush Ltd., unless Mega division agrees to cut the unit transfer price to Sh.22,000. He suggests that if Mega division cannot reduce the price it would be better for it to cease operations and the space it now occupies be taken up by Wazo division, which is currently seeking extra warehouse space. The summarized profit and loss accounts of the divisions for the past year ended 31 October 2001 is as follows: Mega division Wazo division Production and sales (Physical units) 30,000 30,000 Sh. .000.
