Answer:
12 cleaners
Step-by-step explanation:
8 cleaner can clean in 3 hours = 1 office
1 cleaner can clean in 3 hours =
part of job
1 cleaner can clean in 1 hours =
part of job
Let the number of cleaner required to finish the job in 2 hours = x
hence
x cleaner can clean in 1 hours =
part of job
x cleaner can clean in 2 hours =
part of job
Hence
![\frac{2 \times x }{24}=1](https://tex.z-dn.net/?f=%5Cfrac%7B2%20%5Ctimes%20x%20%7D%7B24%7D%3D1)
![\frac{2x}{24}=1](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B24%7D%3D1)
![2x=24](https://tex.z-dn.net/?f=2x%3D24)
![x=12](https://tex.z-dn.net/?f=x%3D12)
Hence we need 12 men to complete the same job in 2 hours
