Answer 1

Nation A's and Nation B's GDP per capital both increased from 2015 to 2016 (b).  

Explanation:

The formula for per capital income =total income/total population. In the year 2015 Nation A's per capital income is 520/150= 3.46 and in the year 2016 Nation A's per capital income is 550/155=3.54 . In the year 2015 Nation B's per capital income is 200/53= 3.77 and in the year 2016 B's per capital income 210/55=3.81.

In both the cases the per capital income has increased from the year 2015 and 2016 for both the nation.
