Answer:
0%
Explanation:
It is easier to explain using an example:
the country's real GDP during year 1 = $1,000,000
the country's population during year 1 = 1,000 people
the real GDP per capita = $1,000,000 / 1,000 people = $1,000 per person
during year 2, both the real GDP and the population grow by 5%
the country's real GDP during year 2 = $1,050,000
the country's population during year 2 = 1,050 people
the real GDP per capita = $1,050,000 / 1,050 people = $1,000 per person
so there has been no change in the real GDP per capita.
