Is Anybody pose any comment .?

How much my solution is correct wrt questions and options?

  I agree with all your answers except for  Q 50. 

50 - B  ( If early start of activity A is May 1 then early finish should be May 2nd )


here 1st May start with one day duration -- means 1st May morning and after 8hours or any normal working duration of a day .

If you say 2ndMay early finish means 2nd may Evening or any normal ending time of that day , which same as for May 1st.


Are You IT guy / Civil const/ Mech Const/ Ele/ any other field

Are you new /experienced 5-10-15 yrs/

Although I have not much idea about these all questions but like to share bestdissertation review about the answers here. The early start of activity F would be May 4. Hope this will be obliging for you.
