Question

One hundred people in a supermarket survey

were asked what kind of pet they own. Forty-
seven people surveyed have only cats, thirty-
three have only dogs and seven have only an
“other” kind of pet. If no one surveyed has
more than one kind of pet, what percent of
the people surveyed do not own a pet?

Answer 1

13%

Explanation:

So basically the people who had a pet in the store were: 47, 33, and 7 out of 100. Now we add up the numbers of the people who have pets which in total, is 87, out of 100. But that's not all. Those are the people who have pets to find the people who didn't have pets, we subtract 87 from 100 to get 13, or 13% as our answer.
