Answer is B - 21
Answer is B - 21 days
Adjusted ES of B= Original ES of B+Delay of A-Float of A = 18+7-4=21

Where is this formula?
Hi Chandra,
You do have a very good understanding of the Float calculations. How did you get this formula and where can I read more as I don't have a good understanding yet of the Float related calculations.
Please help and Rajesh if we could know the source of the questions ... that would be great.
Thanks,
f

There is no formula. I just
There is no formula. I just mathematically deduced and showed how to compute from the given information. Some explanation:
Float is the buffer/cushion you have to get the project tasks going per schedule and use it, if necessary to account for unexpected/unanticipated delays from derailing your project from the scheduled completion. Here you are delayed by 7 days. Luckily you have a cushion of 4 days from A built in when the schedule was developed. so overall you will now be affected by 7-4 =3 days. So everything else gets shifted further by 3 days. So your original ES of B which is 18 days gets bumped up by 3 more days resulting in its adjusted ES to be 18+3 = 21 days.
