Question 1

In a CPM network the activity is non critical if

• AEST > LST and EFT > LFT
• BEST < LST and EFT < LFT
• CEST = LST and EFT < LFT
• DEST < LST and EFT = LFT
  (E=Earliest, S=Slack, F=Float, L=Latest, T=Time)

Question 2

The difference between PERT and CPM is that

• APERT uses probabilistic methodologies of activity duration but CPM does not
• BPERT allows crashing but CPM does not.
• CPERT uses dummy activities but CPM does not.
• DNone of the above.

Question 3

Consider the following statements:
(i) In CPM floats are calculated where as in PERT slacks are used.
(ii) Project crashing can be carried out for both the CPM and PERT
(iii) In PERT probabilistic approach is considered.
(iv) Both PERT and CPM are used for project scheduling
Which one of the following is correct?

• A(i), (ii) and (iii)
• B(ii) and (iii)
• C(i) (iii) and (iv)
• D(i), (ii) and (iv)

Question 4

A): An Activity is critical if total float is zero.
B): Earliest finish time and latest finish time for events of the critical activity are same
Select the correct answer.

• AA is correct but B is not correct
• BB is correct but A is not correct
• Cboth A and B are correct
• Dboth A and B are incorrect
