Abhirap,

Kindly check your email address This email address is being protected from spambots. You need JavaScript enabled to view it., I have re-sent the latest version of the PM Formulas.

Version 5.01

Abhirup,

Please look in the footer of the document you have. What is the version number you see?

"work will continue at the planned rate" this sentence was not in the formula study guide pdf file from www.pmformulas.com which I got as a package when I bought it.

Now with this one, yes I already agree the correct formula is EAC= AC+(BAC-EV).

Thank you Sir

Abhirup,

I'm not sure what version of the Formula Study Guide from www.pmformulas.com you are looking at, but in the current version, the question is as follows:

Question 10: PV = 100, EV = 105, BAC = 400, AC = 102, CV = 3. What is the Estimate to Complete (ETC) assuming that work will continue at the planned rate?

Therefore, the question clearly states that the "work will continue at the planned rate" [= the variance will not happen again]. As such the formula used, answer and explanation are correct.

Also consider looking at this from the perspective of the available answers:

You chose a different formula to calculate the ETC and your result was "286.5". As you can clearly see, that value is not available in the 4 given answers. Therefore, this means that the formula you have chosen does not lead to a "correct" result - at least for this question.

So for the PMP Exam this means: If the formula you are using does not result in a number that is also available as one of the four answers, it means that you have selected the "wrong" formula. At least, it is "wrong" in the sense that it does not result in an available answer.

Does this last bit make sense?

Hi,

I have a doubt in one of the question from 105 question for the formula study guide.


Question 10: PV = 100, EV = 105, BAC = 400, AC = 102, CV = 3. What is the Estimate to Complete (ETC)?
A.) 298
B.) 300
C.) 305
D.) 295


My doubt is while calcuating the EAC, and BAC/CPI formula is not considerd at all.
Insted the following formula is being used : EAC= AC + (BAC-EV);ETC=EAC-AC=295

The question doesn't explicitly mention that the variance will not happen again

The answer is determined assuming that the variance will not happen again and hence the following formula is used:

EAC= AC+(BAC-EV)

Why it is not considered that variance will remain? and the following formula could have been used:

ETC=EAC-AC=BAC/CPI-AC=286.5
