You can put this solution on YOUR website! One job can be done in d days by d men in the group. if the number of men is reduced by 4, the job will be delayed by 5 days. How many men were there originally in the group?
Reducing the number of men to d-4 makes the 1 job require d+5 days.
The d men in d days did one job. The reduced men, more days arrangement was also for one job. The number of jobs is equal.
RT=J for rate, time, job. We can use r for the one-man work rate.
 .
The factor of r occurs on both sides of the equation, and the only other variable resulting in terms in powers of one and two is d. Solve for d.
