4.5%

5.0%

35%

3.5%

growth rate will be 4.5 %

So option A is correct option

Explanation:

We have given immigration = 50

Emigration = 20

Birth rate = 25

Death rate = 10

Each per 1000 people

We have to find the percentage growth rate of this country

Percentage growth is given by immigration - emigration + birth rate - death rate

So percentage growth rate = %

So growth rate will be 4.5 %

So option A is correct option
