A project has four activities $$P,Q, R$$ and $$S$$ as shown below.

The normal cost of the project is Rs. $$10,000/-$$ and the overhead cost is Rs. $$200/-$$ per day. If the project duration has to be crashed down to $$9$$ days, the total cost (in Rupees) of the project is ______________.

Consider the given project network, where numbers along various activities represent the normal time. The free float on activity $$4$$-$$6$$ and the project duration, respectively, are

For a particular project, eight activities are to be carried out. Their relationships with other activities and expected durations are mentioned in the table below.

The critical path for the project is

For a particular project, eight activities are to be carried out. Their relationships with other activities and expected durations are mentioned in the table below.

If the duration of activity $$''f ''$$ alone is changed from $$9$$ to $$10$$ days, then the
