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




Hence we need 12 men to complete the same job in 2 hours
Hope this makes sense, x = 75!!
