Explanation:

Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year

Nominal GDP is GDP calculated using current year prices while Real GDP is GDP calculated using base year prices. Real GDP has been adjusted for inflation.

The standard of living is calculated as real GDP / population. Even though the real GDP of country A grew faster than country B, country A's population might be higher than country B's making its standard of living lower.

To make a conclusion that the growth of country A's worker productivity grew faster, it must be assumed that population grew at the same rate in both countries
