Explanation:

Notice that P= total population and U= number of people in the country with at least one unique Facebook account.
If we consider 100 as total population then the percentage Y will be equivalent to U in case of percentage
i.e P/U=100/Y
so rather than finding out actual value and then finding the ratio,
just find 100/Y for each country and the ratio will be greatest for Japan as it has lowest Y.
So answer is Japan
