Hello everybody here,

I got 2  quetion here first is of simple maths, however i am not able to accept the answer mentioned in the Andy Crowe book.

1 Question is :

We have EV = 127253, BAC = 275,000 and SPI =0.77

We need to calculate how much work was expected to have been completed at this point.

I think it is asking for PV here..

Can any body help me understanding the caculation to caculate PV here.

2 Question

Thanks in advance.
