ETC and PV
(1) 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 $1,000. What is the estimate to complete for the project?
A. $1,100.04
B. $1,000
C. $691.24
D. $1,185.63
(2) Activity A is worth $200, is 100% complete, should have been done on day 1, and actually cost $200. Activity B is worth $75, is 90% complete, should have been done on day 2, and actually cost $120 so far. Activity C is worth $200, is 75% complete and should have been done on day 3, and has cost $175 so far. The total budget is $1,000. What is the planned value as of day 2?
A. $275.00
B. -$417.50
C. $495.00
D. -$275.00
Pls I want to make some comparison with the 2 qs; hope u wouldn't mind the double posts.

1C and 2A
1C
Just sum up EV and AC and calculate EAC=BAC/CPI. Then use the result to calculate ETC=EAC+AC.
2A
Just sum up PV for activity A and B

1AC = 200+120+175 =495BAC =
1
AC = 200+120+175 =495
BAC = EAC = AC+ETC
1000 = 495+ETC
ETC = 1000-495 = 505
-------------------
OR
According to table 10.15 of PMBOK calculating individually EV AC CPI etc.
IF BAC = 1000
EV of A,B,C = 200+75+200 = 475
Remaining EV = 525
EAC = 200+ 75/CPI of B + 200/ CPI of C + 525 (Assume cost impact is typical as 10% and 25% work remained)
EAC = 200 + 75/0.5625 + 200/0.857 + 525 = 1091.67
1091.67 = AC +ETC
=> 1091.67 = 495 + ETC
ETC = 596.67
but both answer are not in options.
---------------------------------------------------
If sum up AC and against EV
AC = 200+ 120 +175 = 495
EV = 200+67.5+150 = 417.5
CPI = 417.5/495 = 0.843434
EAC = 1000/0.843434 = 1185.63
ETC = 1185.63 - 495 = 690.63 APPROX OPTION C
---------------------------------
2
Cummulative planned value at second day is PV = 200 +75 = 275 (OPTION A)
