I would appreciate if anyone can please guide me on the workings to this question from the EPSO site.

In 2000, what was the ratio of GDP in the Netherlands to that in Finland?
Possible Answers: (a) 1:3 (b) 2:3 (c) 3:2 (d) 3:1 (e) None of the above
My reasoning was as follows:
Netherlands GDP | Finland GDP
=============== | ===========
21003 | 21582
1 | 1.028
Which would make (e) None of the above the correct answer.
My problem is that another similar question resulted in the same answer and I am not sure whether my working is correct.
Thanks Paul
