Five men take as much to do a job as 10 women. If 6 men take 10 days to complete a job working 4 hr per day, how much time would 10 women take to do a job twice as much as the former while working 6 hr a day?

Explanation
6 men can do the job in 40 hrs.
Therefore, 12 women can do the same job in 40 hrs
So, 10 women can do the same job in 40*12/10 hrs i.e. 48 hrs
Hence, 10 women can do twice the job in 48*2 = 96 hrs = 16 days working 6 hrs a day.
