Answer:
Step-by-step explanation:
SolutionLet the work by (x-1) men in (x+1) days = 9z
Then, work done by 1 man in 1 days = [9z/(x-1) * 1/(x+1)]
Let the work done by (x+2) men in (x-1) days = 10z
Therefore Work done by 1 man in 1 days = 10z/(x+2)(x-1)
Therefore
9z/(x-1)(x+1) = 10z/(x+2)(x-1)
Solve
x=8
