Matching Floats with Descriptions:

A. Earliest start time of its successor activity minus earliest finish time of the activity in question minus the duration - Interfering Float

B. Time available for an activity performance minus the duration of the activity - Free Float

C. Excess of minimum available time over the required activity duration - Independent Float

D. Difference between total float and free float of an activity - Total Float

The correct match between List-1 and List-11 is:

D. Difference between total float and free float of an activity - Total Float

C. Excess of minimum available time over the required activity duration - Independent Float

B. Time available for an activity performance minus the duration of the activity - Free Float

A. Earliest start time of its successor activity minus earliest finish time of the activity in question minus the duration - Interfering Float

Explanation:

Total Float:

- The amount of time an activity can be delayed without delaying the project's completion date is called Total Float.
- It is calculated by subtracting the earliest start time of the activity from the latest start time of the activity.
- Total Float = LS - ES or LF - EF

Independent Float:

- Independent float is the maximum amount of time that an activity can be delayed without delaying the early start of any of its successor activities.
- Independent Float = ES of succeeding activity - EF of current activity - duration of current activity

Free Float:

- Free float is the maximum amount of time that an activity can be delayed without delaying the early start of its immediate successor.
- Free Float = ES of succeeding activity - EF of current activity

Interfering Float:

- Interfering Float is the amount of time an activity can be delayed without delaying the start time of a specific interfering successor activity.
- Interfering Float = ES of interfering activity - EF of current activity - duration of current activity

Hence, the correct match between List-1 and List-11 is D, C, B, A.

List-I and List-II represent different types of floats associated with activity floats. The correct match between List-I and List-II is given in option 'D'. Let's understand each type of float and its associated name:

1. Total Float: It is the amount of time that an activity can be delayed without delaying the project's finish date. It is calculated as follows:
Total Float = Latest Start Time - Earliest Start Time or Latest Finish Time - Earliest Finish Time

Name of the Float: Total

2. Free Float: It is the amount of time that an activity can be delayed without delaying the start time of its successor activity. It is calculated as follows:
Free Float = Earliest Start Time of Successor Activity - Earliest Finish Time - Activity Duration

Name of the Float: Free

3. Interfering Float: It is the difference between the total float and the free float of an activity. It represents the amount of time that an activity can be delayed without delaying the start time of its successor activity, but delaying the project's finish date. It is calculated as follows:
Interfering Float = Total Float - Free Float

Name of the Float: Interfering

4. Independent Float: It is the excess of minimum available time over the required activity duration. It represents the amount of time that an activity can be delayed without delaying the start time of any other activity or the project's finish date. It is calculated as follows:
Independent Float = Minimum Available Time - Activity Duration

Name of the Float: Independent

Therefore, the correct match between List-I and List-II is as follows:
A - 2 (Free)
B - 1 (Total)
C - 4 (Independent)
D - 3 (Interfering)
