any number from 1-10 multiplied by 9 and added to itself is 9, so when you subtract 5 from it, you will always get 4..which is D and unless you sit around for a few and try to come up with a country other than Denmark...the answer will always be the same. In fact a quick look at names of countries that start in D didn't reveal any other country starting with D except Denmark, etc., etc., etc.

Cheers,
