Question

10 man bind 20 copies in 5 days then in how many days 5 man bind 25 copies . ​

Answer 1

Step-by-step explanation:

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 [math]1/16[/math]

and as they work 6 hrs per day…

the amount of work done by 5 men per hour is [math]1/16/6 [/math]or[math] 1/96[/math]

therefore the amount of work done by 1 man in 1 hr is [math]1/16/6/5[/math] or [math]1/480[/math]

According 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
