Answer Posted / mv jaysheelan
(30Men x 20days x 9hrs)/(40Men) = 135 hrs per day. Which
is impossible. So, the answer is none.
Since the question is vague, if you don't answer this
question you may be given mark for this question.
The question should have been
1. How many days 40 men working 9 hrs a day will take to
complete the work.
Answer: (30Men x 20days x 9hrs)/(40Men x 9 hrs) = 15days
2. How many hours a day should 40 men work for 20days will
take to complete the work.
Answer: (30hrs x 20day x 9hrs)/(40Men x 20days)=6 3/4 hrs
