How many (whole number of) 91 kg people

can safely occupy an elevator that can hold a

maximum mass of exactly 1 metric ton? A

metric ton is 1.000 * 103

kg.

Answer in units of people.

We are given that the maximum mass capacity is 1 metric ton or 1000 kg. Therefore the amount of people this can hold is simply the ratio of the maximum mass capacity over the mass of the person, that is:

people = 1000 kg / 91 kg

people = 10.98

So the elevator can safely occupy 10 people. We will not exceed to 11.
