A plant at Pune works 8 hours per day (480 minutes) and must produce 240 units per day on an assembly line. The total task time per unit is 10 minutes. What is the theoretical minimum number of workstations?
The theoretical minimum is 5 workstations. Cycle time is 480 minutes divided by 240 units, which is 2 minutes. Dividing the total task time of 10 minutes by the 2-minute cycle time gives exactly 5 stations.

- D3
Explanation
Cycle time = 480/240 = 2 minutes. Minimum stations = total task time / cycle time = 10/2 = 5. Choosing 4 would come from wrongly using 8 minutes of cycle time; 6 results from rounding up unnecessarily.

One question tells you little. A timed set on Simulation and Line Balancing shows your real accuracy, how long you take and where you lose marks.
