5 painters can finish the job in 12 days.
How many days it will take 6 painters to finish the job with %50 more wall space.
:
Find the number of man-days required to complete the original job:
5 * 12 = 60 man-days to complete the job
:
Then 1.5(60) = 90 man days to complete a job with 50% more
:
Let d = no. of days required for 6 men to do the new job
6d = 90
d = 90%2F6
d = 15 days
