annual death rate is 3% is equal to 30

100+30 equal to 130

answer is 870

Answer 2

Step-by-step explanation: Population will be 1070

The population of a small village is 1000.

As per the question the annual birth rate is 10% .

and annual death rate is 3%

∴ Annual increase rate is 10% - 3% = 7%.

We need to find the population of the village after 1 year.

∴ By using the below formula we get

A = P(1+R/100)n

(Here A stands for total population,  P stands of the initial population which is 1000, R stands for the increase population rate which is 7% and n for number of years that is 1)

A = 1000(1+7/100)1

A = 1000(1.07)1

A = 1070.

Hope this helps.
