Formulas used are shown in the below table,
Formulas used to calculate ES,EF,LS and LF are shown below:
Forward pass -
ES = Maximum(EF of the predecessor activities)
EF = ES + Mean time
Backward pass -
LF = Minimum(LS of all succeeding activities)
LS = LF - Mean time
Note,
ES for Activity A = 0
LF for activity K = EF for activity K
Critical path is the path with the activities with zero slack
Hence,
critical path is A-B-E-F-H-J-K
Time required for critical path = 43.5 units of time.
