7 PART-B 1. 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 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 makes the factory to run at 85 % of its full capacity, would this be a better proposal than the first one? (8) 2. 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 (25days) workers had an overtime of 150 hours and were paid double than the normal rate. Find (i)the total cost (8) (ii) The man hour rate of overheads. Assume 8 hours working days. (8) 3. What is the material cost of welding two plates of size 300 mm length and 150 mm width and 8 mm thickness to make a piece 300 x 300 mm approximately. Use rightward technique with no edge preparation cost. Take overall cost of oxygen as Rs 0.70 per cu.meter, cost of acetylene as Rs 7 per cu. meter, cost of filler metal to be Rs 2.50 per kg. 1cu.cm of filler metal weighs gms. Assume diameter of filler rod= 4 mm. Filler rod used per meter of weld= 3.4 meter. Rate of welding= 2.1 meter/hour. Consumption of oxygen=consumption of acetylene= 7.1 cu.metre/hr. (16) 4. A 3 cm deep slot is to be milled with a 8 cm diameter cutter. The length of the slot is 30 cm. What will be the total table travel to complete the cut? If the cutting speed is 20 meters/ min and feed per tooth is 0.2 mm. Estimate the milling time. The cutter has 24 teeth and one cut is sufficient for the slot. (16) 5. Estimate the time required for tapping a hole with 25 mm tap (3 mm pitch tap) to length of 50 mm. For return stroke the speed is 1.5 times the cutting speed. Take the cutting speed as 8 m/ min. (16)
