Answer 2

Answer:

The population of the town after 3 years = 382034.8.

Step-by-step explanation:

Given : Population of a town is 3,60,000. The birth rate is 5.8% per annum and the death rate is 3.8% per annum.

To find : What will be the population of the town be after 3 years?

Solution :

The population of a town = 360000.

Rate of increase in population = (5.8 - 3.8) = 2%.

Time n = 3 years.

Applying the formula,

$A = P(1 + \frac{r}{100})^n$

Substitute the values in the formula,

$A = 360000(1 + \frac{2}{100})^3$

$A = 360000(1+0.02)^3$

$A = 360000(1.02)^3$

$A = 360000\times 1.061208$

$A = 382034.88$

Therefore, The population of the town after 3 years = 382034.8.
