The diagram below shows the activities on the nodes, and the table shows the normal time and crash time (in days) and cost for each activity.

$$\begin{array} { | c | c | c | c | }
\hline \text { Activity } & \text { Normal Time } & \text { Crash Time } & \begin{array} { c }
\text { Cost per day } \
\text { to crash }
\end{array} \
\hline \text { A } & 6 & 6 & - - - \
\hline \text { B } & 10 & 8 & \$ 100 \
\hline \text { C } & 5 & 4 & \$ 300 \
\hline \text { D } & 4 & 1 & \$ 700 \
\hline \text { E } & 9 & 7 & \$ 500 \
\hline \text { F } & 2 & 1 & \$ 650 \
\hline
\end{array}$$
-Which activity should be crashed to reduce the project completion by 2 days?
A) Crash activity B by 1 day and Activity C by 1 day.
B) Crash activity E by 2 days.
C) Crash activity C by 1 day and activity E by 1 day.
D) Crash activity B by 2 days.

Quizplus · Accepted Answer

Crashing activity C by 1 day and activity E by 1 day is the most efficient way to reduce the project completion time by 2 days, assuming these activities are on the critical path and have the least cost or impact when crashed.
