A unit recruits cleaners, and each cleaner works for five days and takes two days off. How many cleaners should be hired to ensure that 30 cleaners work every day?

30 times 7 divided by 5 equals 42 people, so there must be at least 42 people.

Calculation basis: 30 times 7 is equivalent to the daily workload times the number of days, which is the total workload.

Suppose there are X people in the recruitment, then X times 5 is also the total workload, then 5 times X is greater than or equal to 30 times 7, and the answer is greater than or equal to 42 people.
