5 men working 6 hours per day, complete the work in 16 days…therefore the amount of work done by 5 men in 1 day is 1/161/16and as they work 6 hrs per day…the amount of work done by 5 men per hour is 1/16/61/16/6or1/961/96therefore the amount of work done by 1 man in 1 hr is 1/16/6/51/16/6/5 or 1/4801/480According to the question,amount of work done by 10 men in 1 day = (1/480) * 10 *8 = (1/6)(which is amt of work done by 1 man multiplied by no. of men and the no. of hrs they work in 1 day)as the 10 men working 8 hrs per day can complete (1/6) of the work in one day, they will take 6 days to complete the work
