---- C is wrong because it’s negative 7 not positive 7, otherwise also D would be correct, hence the only valid answer is A.

Wrong otherwise because it’s negative 7 not positive 7, otherwise also D would be correction, hence the only valid answer is A.

- PV Planned value = 30
- AC Actual cost = 35
- EV Earned value = 28

- Cost Performance Index (CPI) = EV / AC = 28 / 35 = 0.8
- Schedule Performance Index (SPI) = EV / PV = 28 / 30 = 0.93
- Cost Variance (CV) = EV – AC = 28 – 35 = -7
- Schedule Variance (SV) = EV – PV = 28 – 30 = -2
