Question

Calculate total float ,interfering float and independent float for activity 'R'
$\begin{array}{ccc}\text{Activity}& \text{Preceding activity}& \text{Duration}\\ P& -& 2\\ Q& -& 3\\ R& P& 3\\ S& P& 4\\ T& S& 6\\ U& QandR& 4\\ V& UandT& 3\end{array}$

• A. $3,0,3,0$
• B. $3,0,0,3$
• C. $0,0,0,0$
• D. $3,0,0,0$

Answer 1

The correct option is A $3,0,3,0$



EST = 2
LST = 5
EFT = 5
LFT = 8
Total float = LST - EST
= 5-2= 3
Free float = $F_T-S_j=0$
Independent float $=F_F-S_i=0$
So, option (a) $\to$ (3, 0, 3, 0)
