Question

Which of the following is the "amount of time" by which the "start of an activity" may be delayed without delaying the "start of a following activity"?

• A. Interference float
• B. Free float
• C. Independent float
• D. Total float

Hint:

Free float is always less than or equal to total float, and it ensures no delay to successor activities.

Answer 1

The Correct Option is B

Step 1: Recall float definitions.
- Total float: Maximum delay of an activity without affecting project completion time.
- Free float: Delay allowed without affecting the start of the successor activity.
- Independent float: Float available when both the head event and tail event occur at their latest and earliest times.
- Interference float: Portion of total float that, if used, will delay the succeeding activities.

Step 2: Apply to question.
The problem specifically asks: "delay of start of activity without delaying start of following activity." This is exactly the definition of free float.

Step 3: Conclusion.
Correct answer is Free float.
