Answer:
Given,
24 men work 27 days 7 hours each day to complete a piece of work. Let a man can complete x piece of work in an hour.
i.e. power of a man = x (piece of work/hr)
Total work completed by 24 men in 27 days working 7 hours each day is,
total work = 24*x*27*7
now,
Same total work completed by 14 men in y days working 9 hours each day is now given by
total work = 14*x*(y)*9
observe 24*x*27*7 = 14*x*(y)*9
Thus, the equation gives y = 36 days.
So, 14 men takes 36 days to complete the piece of work working 9 hours each day.
