Cost management test questions & suggested solutions

Management Test Questions & Suggested Solutions by L. Muralidharan, FCA. , Grad. CWA. , COST MANAGEMENT – TEST QUESTIONS & SOLUTIONS Question: 1 Bharata Ltd is considering proposals for design changes in one of a range of soft toys. The proposals are as follows: (a) Eliminate some of the decorative stitching from the toy.

(b) Use plastic eyes instead of glass eyes in the toys (two eyes per toy). (c) Change the filling material used. It is proposed that scrap fabric left over from the body manufacture be used instead of the synthetic material which is currently used. The design change proposals have been considered by the management team and the following information has been gathered: (a) Plastic eyes will cost Rs. 15 per hundred whereas the existing glass eyes cost Rs. 20 per hundred. The plastic eyes will be more liable to damage on insertion into the toy.

It is estimated that scrap plastic eyes will be 10% of the quantity issued from stores as compared to 5% of issues of glass eyes at present. (b) The synthetic filling material costs Rs. 80 per tonne. One tonne of filling is sufficient for 2, 000 soft toys. c) Scrap fabric to be used as filling material will need to be cut into smaller pieces before as and this will cost Rs. 0. 05 per soft toy.

There is sufficient scrap fabric for the purpose. (d) The elimination of the decorative stitching is expected to reduce the appeal of the product, with an estimated fall in sales by 10% from the current level. It is not felt that the change in eyes or filling material will adversely affect sales volume. The elimination of the stitching will reduce production costs by Rs. 0. 60 per soft toy. (e) The current sales level of the soft toy is 3, 00, 000 units per annum.

Apportioned fixed costs per annum are Rs. 4, 50, 000. The net profit per soft toy at the current sales level is Rs. 3. Required: (i) Using the information given in the question, prepare an analysis which shows the estimated effect on annual profit if all three proposals are implemented, and which enables management to check whether each proposal will achieve an annual target profit increase of Rs. 25, 000. The proposals for plastic eyes and the use of scrap fabric should be evaluated after the stitching elimination proposal has been evaluated.

(ii) Calculate the ercentage reduction in sales due to the stitching elimination at which the implementation of all three design change proposals would result in the same total profit from the toy as that earned before the implementation of the changes in design. Question: 2 ABC Ltd manufactures a simple garden tool. At present the company is working at full capacity producing the three components A, B, C one of each being required for the assembly of the tool.

Question: 6 The budgeted production for period 7 in the finishing department of a pottery manufacturer is, 4, 500 cups, 4, 000 saucers and 6, 250 plates. In one standard hour a direct operative is expected to be able to finish either, 30 cups, or 40 saucers, or 25 plates. During period 7, 400 direct labour hours were worked and actual production was, 4, 260 cups, 6, 400 saucers and 3, 950 plates.

Required: Using the above information calculate for period 7: (i) The productivity of the direct operatives; (ii) An appropriate ratio expressing the department’s actual production relative to that budgeted; (iii)Another ratio which you consider may be useful to management and explain the meaning of the ratio you have calculated. Question: 7 The Bashyam Co Ltd manufactures a variety of products of basically similar composition. Production is carried on by subjecting the various raw materials to a number of standardised operations, each major series of operations being carried out in a different department. All products are subject to the same initial processing which is carried out in departments A, B and C; the order and extent of further processing then depending upon the type of end product to be produced. It has been decided that a standard costing system could be usefully employed within Bashyam and pilot schemed to be operated for six months based initially only on epartment B, the second department in the initial common same of operations. If the pilot scheme produces useful results then a management accountant will be employed and the system would be incorporated as appropriate throughout the whole firm.

Required: Prepare a brief statement which clearly indicates the reasons for the performance of department B and the extent to which that performance is attributable to department B. the statement should utilize variance analysis to the extent it is applicable and relevant. Question: 8 (i) Mathanakesari Ltd manufactures and sells a single product. In the quarter to 30 November 2002 sales of 10, 000 units were budgeted at a unit selling price of Rs. 5 and a unit contribution of Rs. 1 (after charging variable costs). The budget had been prepared in the previous spring, and proved to be inaccurate.

Actual sales for the November quarter were 7, 000 units at a unit selling price of Rs. 8, giving a unit contribution of Rs. 3. You are required to calculate appropriate sales margin variances on the basis of this information. (ii) When reviewing the results for the quarter to 30 November the sales manager ascertained several additional facts. The total market for the product nationally had been only 45, 000 units during the quarter, and not 50, 000 units as Mathanakesari had originally anticipated.

An index of the selling price levels of competitors’ products had risen to 140, instead of remaining at the level of 100 as originally budgeted. Mathanakesari’s variable costs (all materials) had risen in line with the change in the appropriate commodity price index, which had gone up from the expected level of 100 to an actual level of 125.

You are required to calculate a set of variances to take appropriate notice of this additional information, and to discuss their significance. Question: 9 From past experience a company operating a standard cost system has accumulated the following information in relation to variances in its monthly management accounts: Percentage of total number of variances. 1) Its variances fall into two categories: Category 1: those which are not worth investigating Category 2: those which are worth investigating 64 36 100 (2) Of category 2, corrective action has eliminated 70% of the variances, but the remainder have continued. (3) The cost of investigation averages Rs. 350 and that of correcting variances averages Rs. 550. (4) The average size of any variance not corrected is Rs.

525 per month and the company’s policy is to assess the present value of such costs at 2% per month for a period of five months. You are required to: (a) Prepare two decision trees, to represent the position if an investigation is: (i) Carried out; (ii) Not carried out; (b) Recommend, with supporting calculations, whether or not the company should follow a policy of investigating variances as a matter of routine; (c) Explain briefly two types of circumstance that would give rise to variances in Category 1 and two to those in Category 2; (d) Mention any one variation in the information used that you feel would be beneficial too the company if you wished to improve the quality of the decision-making rule recommended in (b) above. Explain briefly why you have suggested it. Question: 10 Vishwakarma is a builder. His business will have spare capacity over the coming six months and he has been investigating two projects. Project A Vishwakarma is tendering for a school extension contract. Normally he prices a contract by adding 100% to direct costs, to cover overheads and profit.

He calculates direct costs as the actual cost of materials valued on a first-in-first-out basis, plus the estimated wages of direct labour. But for this contract he has prepared more detailed information. Four types of material will be needed: Matl.

Neither X nor W is currently used; X has no foreseeable use in the business, but W could be used on other jobs in place of material currently costing Rs. 6 per unit. The contract will last for six months and requires two craftsmen, whose basic annual wage cost is Rs. 16, 000 each. To complete the contract in time it will also be necessary to pay them a bonus of Rs. 700 each. Without the contract they would be retained at their normal pay rate, doing work which will otherwise be done by temporary workers engaged for the contract period at a total cost of Rs.

11, 800. Three causal labourers would also be employed specifically for the contract at a cost of Rs. 4, 000 each. The contract will require two types of equipment: general- purpose equipment already owned by Vishwakarma, which will be retained at the end of the contract, and specialized equipment to be purchased second-hand, which will be sold at the end of the contract. The general-purpose equipment cost Rs. 21, 000 two years ago and is being depreciated on a straightline basis over a seven-year life (with assumed zero scrap value). Equivalent new equipment can be purchased currently for Rs.

49, 000. Second-hand prices for comparable general-purpose equipment, and those for the relevant specialized equipment, are shown below.

Requirements: (a) Ignoring the possibility of undertaking project B, calculate: (i) The price at which Vishwakarma would tender for the school extension contract if he used his normal pricing method, and (ii) The tender price at which you consider Vishwakarma would neither gain nor lose by taking the contract. (b) Explain, with supporting calculations, how the availability of project B should affect Vishwakarma’s tender for the school extension contract. L.

Muralidharan, FCA. , Grad. CWA. , 7 Sreeram Coaching Point COST MANAGEMENT – TEST QUESTIONS & SOLUTIONS Question: 11 Narendran Products has two main products. X and Y, which have unit costs of Rs. 12 and Rs. 24 respectively.

The company uses a markup of 33? % in establishing its selling prices and the current prices are thus Rs. 16 and Rs. 32. With these prices, in the year which is just ending, the company expects to make a profit of Rs. 3, 00, 000 from having produced and sold 15, 000 units of X and 30, 000 units of Y. This programme will have used all the available processing time in the finishing department. Each unit of X requires an hour of processing time in this department and every unit of Y correspondingly requires half an hour.

Fixed overhead was Rs. 3, 60, 000 for the year and this has been charged to the products on the basis of the total processing hours used. All other cots may be assumed variable in relation to processing hours. In the current year it is estimated that Rs. 60, 000 of the fixed overhead will be absorbed by X and Rs. 3, 00, 000 by Y. With the existing selling prices it is considered that the potential annual demand for X is 20, 000 units and that for Y, 40, 000 units.

You are required to comment critically on the product mix adopted by Narendran Products. Calculate what would have been the optimal plan given that there was no intention of changing the selling prices. (a) For the forthcoming year increased capacity has been installed in the finishing department so that this will no longer be a constraint for any feasible sales programme. Annual fixed overhead will be increased to Rs. 4, 00, 000 as a consequences of this expansion of facilities, but variable costs per unit are unchanged. A study commissioned by the Sales Director estimates the effect that alterations to the selling prices would have on the sales that could be achieved. The following table has been prepared: X Price Demand (‘000) Rs.

Assuming that the company is now willing to abandon its cost plus pricing practices, if these can be shown to be deficient, you are required to calculate the optimal selling price for each product and the optimal output levels for these prices. State clearly any assumptions that you find it necessary to make. Question: 12 Division A of a large divisionalized organization manufactures a single standardized product. Some of the output is sold externally whilst the remainder is transferred to Division B where it is a subassembly in the manufacture of that division’s product.

0. In addition to the external sales, 5, 000 units are transferred annually to Division B at an internal transfer charge of Rs. 29 per unit. This transfer price is obtained by deducting variable selling and packing expense from the external price since this expense is not incurred for internal transfers. Division B incorporates the transferred-in goods into a more advanced product. The unit costs of this product are as follows: L. Muralidharan, FCA.

He argues that the transfers should be made at variable cost plus an agreed (minimal) mark-up since he claims that his division is taking output that Division A would be unable to sell at the price of Rs. 30. Partly because of this disagreement, a study of the relationship between selling price and demand has recently been made for each division by the company’s sales director.

The resulting report contains the following table: Customer demand at various selling prices: Division A Selling price Demand Division B Selling price Demand Rs. 80 7, 200 Rs. 90 5, 000 100 2, 800 Rs. 20 15, 000 Rs. 30 10, 000 Rs. 40 5, 000 The manager of Division B claims that this study supports his case. He suggests that a transfer price of Rs.

12 would give Division A a reasonable contribution to its fixed overheads while allowing Division B to earn a reasonable profit. He also believes that it would lead to an increase of output and an improvement in the overall level of company profits.

Question: 13 Companies RP, RR, RS and RT are members of a group. RP wishes to buy an electronic control system for its factory and, in accordance with group policy, must obtain quotations from companies inside and outside of the group. From outside of the group the following quotations are received: Company A quoted Rs.

33, 200. Company B quoted Rs. 5, 000 but would buy a special unit from RS for Rs. 13, 000. To make this unit, however, RS would need to buy parts from RR at a price of Rs. 7, 500. The inside quotation was from RS whose price was Rs.

48, 000. This would require RS buying parts from RR at a price of Rs. 8, 000 and units from RT at a price of Rs. 30, 000. However, RT would need to buy parts from RR at a price of Rs. 11, 000. Additional data are as follows: (1) RR is extremely busy with work outside the group and has quoted current market prices for all its products.

(2) RS costs for the RP contract, including purchases from RR and RT, total Rs. 2, 000. For the Company B contract it expects a profit of 25% on the cost of its own work. 9 Sreeram Coaching Point L. Muralidharan, FCA. , Grad. CWA.

Toronto Business Associates currently has 25 consultants on staff, 10 for management consulting and 15 for computer systems consulting. Three additional management consultant have been hired to start work at the beginning of the fourth quarter in order to meet the increased client demand. • The hourly billing rate for consulting revenue will remain at 90 per hour for each management consultant and 75 per hour for each computer consultant. However, due to the favorable increase in billing hour volume when compared to the plan, the hours for each consultant will be increased by 50 hours per quarter.

• The budgeted annual salaries and actual annual salaries, paid monthly, are the same: 50, 000 for a management consultant and 46, 000 for a computer consultant. Corporate management has approved a merit increase of 10 percent at the beginning of the fourth quarter for all 25 existing consultants, while the new consultants will be compensated at the planned rate. • The planned salary expense includes a provision for employee fringe benefits amounting to 30 percent of the annual salaries. However, the improvement of some corporate wide employee programs will increase the fringe benefits to 40 percent. • The original plan assumes a fixed hourly rate for travel and other related expenses for each billing hour of consulting. These are expense that are not reimbursed by the client, and the previously determined hourly rate has proven to be adequate to cover these costs. • Other revenue is derived from temporary rentals and interest income and remains unchanged for the fourth quarter.

General and administrative expense have been favourable at 7 percent below the plan; this 7 percent savings on fourth quarter expenses will be reflected in the revised plan. • Depreciation of office equipment and personal computers will stay constant at the projected straight-line rate. • Due to the favourable experience for the first three quarters and the division’s increased ability to absorb costs, the corporate management at Maple Leaf Services has increased the corporate expenses allocation by 50 percent. Required: 1) Prepare a revised operating budget for the fourth quarter for Toronto Business Associates that Ramachandran will present to corporate management. 2) Discuss the reasons why an organization would prepare a revised operating budget. Question: 17 Ford ltd. anufactures and sells 15, 000 units of a raft, RF17, in 2001.

The full cost per unit is Rs. 200. Ford earns a 20% return on an investment of Rs. 18, 00, 000 in 2001. Required: (1) Calculate the selling price of RF17 in 2001. Calculate the markup percentage on the full cost per unit of RF17 in 2001. (2) If the selling price in requirement 1 represents a markup percentage of 40% on variable costs per unit, calculate the variable cost per unit of RF17 in 2001 (3) Calculate ford’s operating income if it had increased the selling price to Rs.

230. at this price ford would have sold 13, 500 units of RF17. Assume no change in total fixed costs. Should ford have increased the selling price of RF17 to Rs. 230? 4) In response to competitive pressure, ford must reduce the price of RF17 to Rs. 210 in 2002, in order to achieve sales of 15, 000 units. Ford plans to reduce its investment to Rs.

16, 50, 000. If ford wants to maintain a 20% return on investment, what is the target cost per unit in 2002? L. Muralidharan, FCA. , Grad. CWA. , 13 Sreeram Coaching Point COST MANAGEMENT – TEST QUESTIONS ; SOLUTIONS Question: 18 Amrutha, president of PAL Electronics (PE), is concerned about the prospects of one of its major products. The president has been reviewing a marketing report with Krishna, marketing product manager, for their 10-disk car compact disk (CD) changer.

The report indicates another price reduction is needed to meet anticipated competitors’ reductions in sales prices. The current selling price for their 10-disk car CD changers is Rs. 350 per unit. It is expected that within three months PE’s two major competitors will be selling their 10-disk car CD changers for Rs. 300 per unit. This concerns Amrutha because their current cost of producing the CD changers is Rs. 315, which yields a Rs.

35 profit on each unit sold. The situation is especially disturbing because PE had implemented an activity-based costing (ABC) system about two years ago. The ABC system helped them better identify costs, cost pools, cost drivers, and cost reduction opportunities. Changes made when adopting ABC reduced costs on this product by approximately 15 percent during the last two years. Now it appears that costs will need to be reduced considerably more to remain competitive and to earn a profit on the 10-disk car CD changers. Total costs to produce, sell, and service the CD changer units are as follows: 10-Disk Car CD Changer Per Unit Material Purchased components All other material Labor Manufacturing, direct Setups Materials handling Inspection Machining Cutting, shaping, and drilling Bending and finishing Other Finished-goods warehousing Warranty Total unit cost Rs. 110 40 65 9 18 23 21 14 5 10 Rs.

315 Amrutha has decided to hire Damodar, a consultant, to help decide how to proceed. After two weeks of review, discussion, and value engineering analysis, Chandran suggested that PE adopt a just-intime (JIT) cell manufacturing process to help reduce costs. He also suggested that using target costing would help in meeting the new target price. By changing to a JIT cell manufacturing system, PE expects that manufacturing direct labor will increase by Rs. 15 per finished unit. However, setup, material handling, inspection, and finished goods warehousing will all be eliminated. Machine costs will be reduced from Rs.

35 to Rs. 30 per unit, and warranty costs are expected to be reduced by 40 percent. Required: (1) Determine PAL Electronics’ unit target cost the Rs. 300 competitive sales price while maintaining the same percentage of profit on sales as is earned on the current Rs. 350 sales price. 2) If the just-in-time cell manufacturing process is implemented with the changes noted, will PAL Electronics meet the unit target cost you determined in requirement (3)? Prepare a schedule detailing cost reductions and the unit cost under the proposed JIT cell manufacturing process. Question: 19 The management of Alliance Enterprises recently decided to adopt a just-in-time inventory policy to curb steadily rising costs and free up cash for purposes of investment.

The company anticipates that inventory will decrease from Rs. 36, 00, 000 to Rs. 6, 00, 000, with the released funds to be invested at a 12 percent return for the firm. Additional data follow: L. Muralidharan, FCA. Grad. CWA.

, 14 Sreeram Coaching Point COST MANAGEMENT – TEST QUESTIONS & SOLUTIONS • Reduced inventories should produce savings in insurance and property taxes of Rs. 27, 000. • Alliance will lease 75 % of an existing warehouse to another firm for Rs. 2 per square foot. The warehouse has 30, 000 square feet. • Because of the need to handle an increased number of small shipments from suppliers, Alliance will remodel production and receiving-dock facilities at a cost of Rs. 6, 00, 000.

The construction costs will be depreciated over a 10-year life. • A shift in suppliers is expected to result in the purchase and use of more expensive raw materials. However, these materials should give rise to fewer warranty and repair problems after Alliance’s finished product is sold, resulting in a net savings for the firm of Rs. 25, 000. • Three employees who currently earn Rs. 30, 000 each will be directly affected by the just-in-time adoption decision. Two employees will be transferred to other positions with Alliance; one will be terminated.

• Reduced raw material inventory levels and accompanying stockouts will cost Alliance Rs. 70, 000. Required: (1) Compute the annual financial impact of Alliance’s decision to adopt a just-in-time inventory system. (2) If the just-in-time system is implemented in proper fashion, what is the likelihood of excessive raw material stockouts? Briefly explain. (3) Adoption of a just-in-time purchasing system will often result in less need for the inspection of incoming materials and parts. Why?

Question: 23 SumantraTechnologyLtd. ,. manufactures several different types of printed circuit boards; however, two of the boards account for the majority of the company’s sales. The first of these boards, a television circuit board, has been a standard in the industry for several years.

The market for this type of board is competitive and price-sensitive. Sumantra plans to sell 65, 000 of the TV boards in 2001 at a price of Rs. 50 per unit. The second high-volume product, a personal computer circuit board, is a recent addition to Sumantra’s product line. Because the PC board incorporates the latest technology it can be sold at a premium price. The 2001 plans include the sale of 40, 000 PC boards at Rs. 300 per unit.

L. Muralidharan, FCA. , Grad. CWA. , 16 Sreeram Coaching Point COST MANAGEMENT – TEST QUESTIONS & SOLUTIONS Sumantra’s management group is meeting to discuss how to spend the sales and promotion Rupees for 2001. The sales manager believes that the market share for the TV board could be expanded by concentrating Sumantra’s promotional efforts in this area. In response to this suggestion, the production manager said, ” Why don’t you go after a bigger market for the PC board? The cost sheets that I get show that the contribution from the PC board is more than double the contribution from the TV board.

I know we get a premium price for the PC board. Selling it should help overall profitability. ” The cost-accounting system shows that the following costs apply to the PC and TV boards. PC Board Direct material Direct labour Machine time Rs. 140 4 hr. 1. 5 hr.

TV Board Rs. 80 1. 5 hr. . 5 hr. Variable manufacturing overhead is applied on the basis of direct-labor hours. For 2001, variable overhead is budgeted at Rs.

1, 20, 000, and direct-labor hours are estimated at 2, 80, 000. The hourly rates for machine time and direct labor are Rs. 10 and Rs. 14, respectively. The company applies a material-handling charge at 10 percent of material cost. This material-handling charge is not included in variable manufacturing overhead. Total 2001 expenditures for direct material are budgeted at Rs.

1, 06, 00, 000. Andrew Fulton, Sumantra’s controller, believes that before the management group proceeds with the discussion about allocating sales and promotional Rupees to individual products, it might be worth while to look at these products on the basis of the activities involved in their production. Fulton has prepared the following schedule to help the management group understand this concept. ” Using this information,” Fulton explained, ” we can calculate an activity-based cost for each TV board and each PC board and then compare it to the standard cost we have been using.
