I have gone through solutions of both Gurukripa( given above) as well as Parag Gupta Sir (/forum/details.asp?mod_id=175890&offset=1) , but I have found difference in solutions of 2-3 questions (e.g. Solutions of Question 2(b) (ii) & (iii), Question 3(a) (ii), Question 3(b), Critical paths in Quest 6(a), Question 5(a)).
Plz check both of them & let me know that whose solutions are correct. So whose solutions shall be followed.
I have also found that both of them have done several question liks Question 4(b) by different method, so please let me know whose method is simpler & hence shall be followed.
