Q1:

Pick up the incorrect statement from the following:

A The difference between the earliest start time and latest finish time of any activity, is the maximum time available for the activity

B The difference between the maximum time available for the job and actual time it consumes, is called total float

C The difference between the latest start time and earliest start time of an activity, is called total float

D The difference between the earliest finish time of an activity and the earliest start time of its successor activity, is called free float of the activity

E None of these.

ANS:E - None of these.

Actually, option D is wrong because in the case of free float it is the maximum time that can be delayed without affecting the start of the successor activity.

Thus it is Est of successor-Est of predecessor-duration.
