if 12 men working 2 hours a day take 10 days to complete a job, how long will 8 men working 6 hours a day take to do the same work?

• 5 days take to do same work.
  
  12 men working 2 hours in a day means,
  = 12 * 2hrs
  = 24hours of work complete in 1day.
  Therefore for 10 days,
  = 10 *24hours
  = 240hours of work done by 12men.
  
  8 men working for 6hours in a day means,
  = 8 *6hours
  = 48hours of work is completed in 1 day.
  Therefore,
  = 240/48
  = 5days take to work by 8 men for 6hours in a day.
