8:43 Ans b - Minimum time required for producing a garage = 10 minutes for punching + 15 minutes for forming + 5 minutes of welding + 10 minutes of final assembly = 40 minutes Ans c - Capacity of garages per hour is 1.5 garages per hour. Calculation = 1 garage in minutes meaning 6 garages in 240 minutes / 4 hours. Hence garages per hour = 6/4 = 1.5 Ans d - To increase the capacity the base forming stage should be put in some additional resources as it takes the longest time in the process. With additional resources the time will not reduce however the bottleneck or the bases accumulated at the stage after punching will reduce thus reducing the overall time taken for the process to complete and increasing the capacity. Results will vary with different number of additional resources. Ans a
