Verified Answer
Locomotive engines are manufactured in a factory at Rampur. The proces...
The two individuals (say P and Q) can parallely work on two activities.
Say P starts A1 and Q starts A2 on Day 1.
So, A2 gets completed by Day 4 while A1 is still going on.
Since A3 requries completion of only A2, Q can immediately start it on Day 5 and finish it by Day 12.
Similarly, when A1 gets completed on Day 6, P can start A4 and work on it from Day 7 to Day 9. Since A3 is still going on, P can finish A6 from Day to Day 12.
Similarly, the progress of each activity is as shown in the table above. Since the engine is manufactured when either A9 or A10 are complete, the minimum number of days in which the manufacture is complete is 27 days (when A9 is completed).
Hence, option 4.
