How to solve listed EV Question

 Hi, please help me to solve EV question below

Activity A is worth $300, is100% complete and cost $350. Activity B is $100 worth, is 95% complete andactually cost $85 so far. Activity C is worth $ 200, is 75% complete and hascost $ 175 so far. Total Budget is $1500. What is EAC for the activities listed?

 

Options are

A.     $1706

B.    $0.88

C.    $1685

D.    $185

EV=300+95+150(200*.75)=545

AC=350+85+175=610

BAC=1500

CPI= EV/AC=.893

EAC=BAC/CPI =1500/.893 =1685

Thank you for detailed explanation.

Hi,

Can you please explain, How to calculate this. The Question was no doubt ambigious but the answer is also not clear.

Please explaing the steps you have performed while calculating this EV.

In a large project a single cost baseline can be broken in to mulitple cost baselines say A may be used for tracking production cost, B  for purchase cost etc

So in this question Earned Value for the entire project ( measure of work completed) = EV of A+EV of B+EV of C

  EV of A = 300 *100/100 = 300 (Activity A is worth $300, is100% complete)

 EV of B = 100*95/100 = 95 (Activity B is $100 worth, is 95% complete)

EV of C = 200*75/100 =150 (Activity C is worth $ 200, is 75% complete)

Total EV =300+95+150=545

 Total AC=350+85+175=610 (cost of Activity A=350, Activity B=85, Activity C=175)

BAC=1500 (Total Budget is $1500 )

CPI= EV/AC=.893

EAC=BAC/CPI =1500/.893 =1685

 Please let me know if its still not clear

Thanks for the explanation.... Actually I was abit confused on ur first explanation.

Thanks alot again..

 I saw PMBOK4 mention Four Formula's for EAC and ETC.

In that case how would we know which formula of EAC or ETC we need. Any good tip.
