Submitted by niteshrs on Wed, 05/25/2011 - 14:01

Q. Activity A is worth $200, is 100% complete and actually cost $200. Activity B is worth $75, is 90% complete, and actually cost $120 so far. Activity C is worth $200, is 75% complete, and has cost $175 so far. The total budget is $1000. What is the schedule variantce of the activities listed?


A. -$77.50
B. -$57.50
C. 0.84
D. 0.88


The answer given is B. How do we arrive at the calculation? I tried the below calculation


 










































Activities Worth %Complete AC($) PV EV
A 200$ 100% 200 200 200
B 75$ 90% 120 75 108
C 200$ 75% 175 200 131.25
        475 439.25

 


 


PV = Planned%Complete x Project Budget
EV = Actual%Complete x Project Budget
SV = EV - PV


SV = 439.25 - 475 = -35.75


How is -$57.50 arrived? Kindly explain the correct calculation. Thanks
