# eac question

hi all

i found one question regarding eac calculation that the answers contains 2 answers.

eg:\$20, \$1.666

\$40, \$1.666

\$60, \$1.666

\$80, \$1.666

can anybody let me know where i can find samples for the above? ### What is the question ?

### eac question

Hi

I got the question that i wanted. please see the question below

 As a project manager, you are required to produce project performance reports on a regular basis, your project`s Budget at Completion is \$750,000, planned value is \$100,000, schedule variance is \$30,000, and cost variance is \$50,000. What is the percentage complete and estimate at completion in your project? Choice 1 18%, \$ 500,000 Choice 2 17.33%, \$ 461,538 Choice 3 17.8%, \$ 437,500 Choice 4 18%, \$ 437,500 Correct Choice : 2 Justification : SV = EV – PVEV = SV + PV= 30,000 + 100,000= 130,000CV= EV – ACAC=EV- CV =130,000 – 50,000= 80,000

am confused with the logic behind calculation of EV and CV. i mean when it will be plus or minus. have a look at the ev and cv calculation and their corresponding _ and + signs used in EV and CV. am bit confused. please help!

### SV=EV-PV.  This relation is

SV=EV-PV.  This relation is re-written to get the value of EV. Just relax and add PV to both sides of the equation.  Then it becomes:  SV+PV=EV or re-write: EV=SV+PV.  Same thing for CV,EV, AC relation.

% Completed = 100* EV/EAC = 100* 130,000/750,000 = 17.33%

CPI = EV/AC =130,000/80,000 =1.625

If you go at this rate throughout the project, EAC = BAC/CPI = 750,000/1.625 = \$461,538

### Question

How did you know to use the EAC (present CPI) formula? I was trying to use the budget rate formula AC+BAC-EV. Did you use it b/c the question asked about performance reports? I'm just curious; I want to make sure I know what to look for if I have a similar question on the exam.
