How many hours to complete the job?

Thirty men take 20 days to complete a job working 9 hours a day.How many hour a day should 40 men work to complete the job?
Answer: 
6.75hours



Before.....
one day work=1/20
one hour work=1/(20x9)
one men work=1/(20x9x30)


now....

one day work=1/20
one hour work=1/(20xY)
one men work=1/(20xYx40)
ie, 1/(20x9x30) = 1/(20xYx40)
after calculation Y=27/4
Y=6.75hours.
