If 60 cleaners take 12 days to clean a school, then twice the number of cleaners will be needed to clean a school in half the time.
60 cleaners —> 12 days
120 cleaners —> 6 days
24 cleaners —> 30 days
30 days = 6 days x 5
So, the number of cleaners required to clean the school in 30 days = 120 cleaners divided by 5.
60 cleaners —> 12 days
120 cleaners —> 6 days
24 cleaners —> 30 days
30 days = 6 days x 5
So, the number of cleaners required to clean the school in 30 days = 120 cleaners divided by 5.
