How many weeks will it take to complete the project?

____ Number of weeks   

Solution

Activity A, 1 week

Now Activity B takes 4 weeks

Hence total time = 1+4 = 5 weeks

Now Activity C takes 3 weeks but also before that Activity A takes 1 week hence Activity C will be completed in 4 weeks

Now Activity D will be completed in (2+4+1) = 7 weeks

Activity E will be completed in (5+3+1+2+4+1) = 16 weeks

Activity F will be completed in (2+2+4+1) = 9 weeks

Activity G will be completed in (2+2+2+4+1) = 11 weeks

Activity H will be completed in (3+11+16) = 30 weeks

Total number of weeks to complete the project = 1+4+5+4+7+16+9+11+30 = 87 weeks
