Answer = 21/2 days or 10 and 1/2 days
It takes 14 electricians 18 days to wire a new housing subdivision.
One electrician take more time to wire a new housing subdivision.
So one electrician take 14 x 18 days to complete the job.
Therefore 24 electricians take less time to complete the job.
Number of days taken by 24 electricians to wire a new housing subdivision.= (14 x 18 )/24=21/2 days
Therefor 24 electricians take (14 x 18 )/24=21/2 days
