UNIT-III INTRODUCTION TO COST ESTIMATION
1. Explain the type of cost estimates, that are used in estimating . (16)
2. List and discuss the different methods of cost estimating. (16)
3. List the various data required to make a cost estimate (16)
4. List the various types and sources of data required by the cost estimator. (16)
5. Describe the various constituents of estimation. (16)
UNIT-IV COST ESTIMATION
1. List various components of cost (16)
2. Explain the terms prime cost, factory cost, total cost and selling price. Show the relationship between various components of cost with the help of a block diagram.(16)
3. Describe with a block diagram how the selling price of a product is arrived at?(16)
4. Illustrate the relationship between 'elements of cost' and 'components of cost' with the help of a block diagram. (16)
5. Write down the step by step procedure for estimating the direct materials cost ?(16)
UNIT-V PRODUCTION COST ESTIMATION
1. An isometric view of a work piece is shown in figure. What will be the weight of the material required to produce it. The density of material is 2.681 gm/cc. Find also the material cost if its rate is Rs.13.60 per kg All dimensions are in mm. , (16)
2. Estimate the weight of material required for manufacturing 220 pieces of shaft as shown in figure. The shafts are made of mild steel which weighs 7.87 gm/cm3 and costs Rs.4.25 per kg. Also calculate the material cost for 220 such shafts. (16)
3. For manufacturing a ‘milling machine’, the expenditure is tabulated in table. (16)
4. A factory has a capacity to produce 1000 shapers/annum. But at present ‘it is working at its 70% capacity. The sales income at this level is Rs.52,50,000. The fixed cost of the factory is Rs.20,00,000 and variable cost per piece is Rs.2500. There is a proposal for mechanization but this will increase the fixed cost by Rs.40,000 and will reduce the variable cost by Rs.500 per unit.
Estimate: (i) Whether the proposal is economical? (8)
(ii) If a reduction in selling price by Rs.200 per unit make the factory to run at 85 % of its full capacity, would this be a better proposal than the first one. (8)
5. A C.I. factory employees 25 persons It consumes material worth Rs. 35,000 pays workers at the rate of Rs. 5 per hour and incurs total overheads of Rs.20,000. In a particular month (25 days) workers and an overtime of 150 hours and were paid double than the normal rate. Find (i) the total cost, and (8)
(ii) the man hour rate of overheads. Assume 8 hours working days. (8)
