  Use the above listing of tasks to answer the following questions from PERT diagram. Check each of the following paths whether it is valid or not (if yes, write valid and mention the cost/duration of it in number of days; and if not, just write invalid):-(a) Start => D => H => L => End?(b) Start => B => F => I => K => L => End?(c) Start => A => C => I => J => L => End?(d) Start => A => C => I => K => L => End? Out of the valid paths for your solution above, identify the critical path and mention the cost/duration of it in number of days.
