Maths PMP questions : Interesting

Hi,

Can any member post atleast 1 question here in this thread per day related to calculations.

My intention is it will help us all and clarify doubts/ cover gaps...

Appreciate in advance!

 

To start with Question for day Nov 19th:

1>You are a Project Manager for Groceries R' US, a supermarket chain, and are currently working on a project to build a new outlet. The planned values (PV) for the foundation and the frame are $150,000 and $500,000. After five months, you do a performance measurement analysis. You are currently not ahead of schedule. The actual costs for the foundation and frame were $175,000 and $650,000 up to this point where 100% of the foundation is complete and only 80% of the frame is complete. Which value represents the cost performance index (CPI) to two decimal places at this point in the project?

A.   0.84

B.   1.5

C.   0.67

D.   1.19

 

Answewr with deatiled explanation please:-

 

EV = 150 K + 80 % of 500 K = 550 K

AC = 175 K + 650 K = 825 K

CPI = EV / AC = 550 K / 825 K = 0.67
