(e) State the correct answer (= 1 mark) showing your workings (= 2 marks) for each of the following two problems. (1+2)x2
(i) Division R makes a single product. Information for the division for the year just ended is
Rs. 30,000 units
Head Office assesses divisional performance by the residual income achieved. It uses a cost of capital of 12% a year.
Division R’s average contribution per unit was
A—Rs. 148.20; B—Rs. 228.10; C—Rs. 280.60; D—Rs. 310.56.
(ii) Brilliant Ltd. has developed a new product. The nature of Brilliant’s work is repetitive and it is usual for there to be an 80% learning effect when a new product is developed. The time taken for the first unit was 22 minutes. Assuming that an 80% learning effect applies, the time to be taken for the fourth unit is nearest to
A—9.91 mins; B—9.97 mins; C—14.08 mins; D—15.45 mins.
[The exponent b in the formula Yx = aXb is given as — 0.322 for an 80% learning curve.]
2. (a) The research and development department of Innovative Ltd. has produced specifications for two new products. Modalf and Modbet for consideration by company’s production director. The director has received detailed costings which can be summarized as follows:
Labour (Rs. 3 per hour) 64
(Rs. 3 per machine hour)
Total estimated unit cost 18
The sales department has provided estimates of the probabilities of various levels of demand for two possible prices for each product. The details are as follows:
Low price alternative selling price
Most likely–probability 0.5
High price alternative:
Most likely–probability 0.5
Optimistic–probability 0.3 120
It would be possible to adopt the low price alternative for either product together with the high price alternative for the other product (demand estimates are independent for the two products).
The factory has 60,000 machine hours available during the year. For some year past it has been working at 90% of practical capacity making a standardized product. This product is very profitable and it is only the availability of 6,000 hours of spare machine capacity that has made it necessary to search for additional product lines to use the machines fully. The actual level of demand will be known at the time of production.
The monthly fixed cost is estimated at Rs. 10,000 and the variable cost at Re. 1 per machine hour.
The management seeks your advice for the best plan for the utilization of the 6,000 machine hours, to comment on the rational selling price alternatives that exist for this plan and to calculate the expected increase in annual profit which would arise for each alternative.
(b) (i) Briefly describe the operation of an MRP system. 3 (0)
(ii) Ho MRP II differs from MRP I? 2 (0)
3. Sun Ltd. is considering renting additional factory space to make two products. P – 1 and P – 2. You are the company’s management accountant and have prepared the following monthly budget:
P – 1
Rs. P – 2
Variable material and labour costs
Fixed production overhead
(allocated on direct labour hours)
Fixed administration overheads
(allocated on sales value)
The fixed overheads in the budget can only be avoided if neither product is manufactured. Facilities are fully interchangeable between products.
As an alternative to the manual production process assumed in the budget, Sun Ltd. has the option of adopting a computer aided process. This process would cut variable costs of production by 15% and increase fixed costs by Rs. 12,000 per month.
The management is not sure about demand for the new products.
The management believes the company will have to depart from its usual cash sales policy in order to sell P – 2. An average of three months credit would be given and bad debts and administration costs would probably amount to 4% of sales revenue for this product.
Both products will be sold at the prices assumed in the budget. Sun Ltd. has a cost of capital of 2% per month. No stocks will be held.
(a) Calculate the sales revenues at which operations will break–even for each process (manual and computer aided) and calculate the sales revenue at which Sun Ltd. will be indifferent between the two process:
(i) If P – 1 alone is sold;
(ii) If P – 1 and P – 2 units are sold in the ratio 4 : 1, with P – 2 being sold on credit.
(b) Explain the implications of your results with regard to the financial viability of P – 1 and P – 2.
4. (a) What is lean manufacturing? Briefly describe the lean/JIT system. 10 (0)
(b) In the matter of operations management state any five options that can be used to adjust capacity to match current demand. 5 (0)
5. (a) A company is considering whether to develop and market a new product. Development costs are estimated to be Rs. 1,80,000, and there is a o.75 probability that the development effort will be successful and a 0.25 probability that the development effort will be unsuccessful. If the development is successful, the product will be marketed, and it is estimated that
(iii) If the product is very successful profits will be Rs. 5,40,000;
If the products is moderately successful profits will be Rs. 1,00,000;
If the product is a failure there will be a loss of Rs. 4,00,000.
Each of the above profit and loss calculation is after taking into account the development costs of Rs. 1,80,000.
The estimated probabilities of each of the above events are as follows:
(3) Very successful
(i) Prepare decision tree;
(ii) Offer your comments
(b) Identify the assumptions on which cost–volume profit analysis is based. 5 (0)
6. (a) Explain the concept of learning curve and state how relevant is the same is managing cost. 5 (0)
(b) A company has developed a special purpose Electronic Security Device and once introduced in the market, the same expected to have a life cycle of 3 years from the time of its introduction in the market before the Device becomes obsolete due to technological and advancement of other competitive products.
You have been asked by the company to prepare a product life cycle budget.
The following information are available:
Year 1 Year 2 Year 3
No. of units to be manufactured and sold
