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

Level One:10
Level Two: 10x3=30
Level Three: 30x3=90
Level Four: 90x3=270
Level Five: 270x3=810
Level Six: 810x3=2430
Level Seven: 2430x3= 7290
