A project has $4$ tasks, namely, A$,$ B$,$ C$,$ and D$.$

The baseline estimate for project completion time is $20$ days.

A$,$ B$,$ and $C$ have no predecessors.

$C$ is a predecessor to $D.$

As per the status date:

A and B should have been completed $100\%.$

C should have been completed $75\%.$

Baseline cost for these tasks are: $A=20,B=15,C=30,$ and $D=20.$

Actual progress went as:

$A=100\%$ finished at actual cost of $25$ ;

$B=80\%$ at Actual cost of $10$ ;

$C=50\%$ at actual cost of $20.$

Calculate PV$,$ EV$,$ AC$,$ CV$,$ SV$,$ CPI, SPI, baseline project duration, budget at co estimate at completion, and the new time estimate to complete the project done so far?
