The figure shows a network diagram for a construction project. The activities $\mathrm{A}, \mathrm{B}, \mathrm{C}$, D, E, and F are represented by arrows and their durations are in the figure.
The total float available for the activity E in day(s) is equal to _________ (round off to the nearest integer).
A critical activity in a project is estimated to take 15 days to complete at a cost of Rs. 30,000. The activity can be expedited to complete in 12 days by spending a total amount of Rs. 54,000. Consider the statements P and Q.
P: It is economically advisable to complete the activity early by crashing, if the indirect cost of the project is Rs. 8,500 per day.
Q: It is economically advisable to complete the activity early by crashing, if the indirect cost of the project is Rs. 10,000 per day.
