To determine which country has the highest GNI per capita, we need to calculate the GNI per capita for each country using the formula:
\[ \text{GNI per capita} = \frac{\text{GNI}}{\text{Population}} \]
Let's calculate the GNI per capita for each country:
-
Country A:
- GNI = US$3,900
- Population = 80
- GNI per capita = \( \frac{3900}{80} = 48.75 \)
-
Country B:
- GNI = US$4,500
- Population = 200
- GNI per capita = \( \frac{4500}{200} = 22.5 \)
-
Country C:
- GNI = US$10,000
- Population = 1,000
- GNI per capita = \( \frac{10000}{1000} = 10 \)
-
Country D:
- GNI = US$2,000
- Population = 200
- GNI per capita = \( \frac{2000}{200} = 10 \)
Now, let's summarize the GNI per capita calculations:
- Country A: GNI per capita = 48.75
- Country B: GNI per capita = 22.5
- Country C: GNI per capita = 10
- Country D: GNI per capita = 10
From these calculations, Country A has the highest GNI per capita at US$48.75.
