Question 411633
if 4 painters complete a painting job in 15 days working 8 hours per day,
 How long would it take 6 painters working 10 hours per day to finish the job?
:
Find the man-hrs to complete the job
4 * 15 * 8 = 480 man-hrs
:
Let d = no. days when 6 men work 10 hrs per day
6 * 10 * d = 480
60d = 480
d = {{{480/60}}}
d = 8 days, 6 men working 10 hrs a day
