It is given that the job can be performed by 10 men in 24 days by working 8 hours a day.
Let x be the number of days required by 8 men to perform the same job working 12 hours a day.
Since, the total time required to perform the job in both the cases is same.
\(\therefore\) 8 men would require 20 days to perform the same job working 12 hours a day.
