b) 7 days, 5 workers
c) 5 days, 7 workers
d) 8 days, 3 workers

Answer 1

c) 5 days, 7 workers

Step-by-step explanation:

The longest task is Task-1 which takes 5 days.

All the tasks are parallel. So, the length of the project should be 5 days. The resources employed are just the total of all the tasks i.e. 2+2+1+1+1 = 7.

5 days, 7 workers
