The puzzle goes something like this

In the US every 13th libertarian is a pescatarian and every 11th pescatarian is a libertarian. Are there more libertarians or pescatarians?

The obvious answer seems incorrect to me, yet I don’t know how to go about solving this correctly.

    Suppose there are $n$ people who are both. How many libertarians are there in total in terms of $n$? How many pescatarians in total in terms of $n$? Which is bigger? – JMoravitz Feb 10 '22 at 13:59

    "The obvious answer seems incorrect to me" What do you think to be the obvious answer and why do you think it to be incorrect? – JMoravitz Feb 10 '22 at 14:00
