Answer:

Total population after 3 years and 4 months = 116667

Explanation:

Concept:

Percentages

Given:

Population of town = 100000

Birth rate = 5%

Death Rate = 0%

To Find:

The population of the town after 3 years and 4 months

Solution:

Population growth in one year = 5%(given)

Population growth of one year = $100000*\frac{5}{100} =1000*5 = 5,000$

Population growth of three years = Population growth of one year x 3

Population growth of three years = 15,000

Now, Convert 4 months in terms of the year

12 months = 1 year

1 month = $\frac{1}{12}$ year

4 months =$\frac{4}{12}=\frac{1}{3}$ year

Population growth of 4 months = Population growth of one-year x $\frac{1}{3}$

Population growth of 4 months = $5000 *\frac{1}{3} =1667$(Approx)

Total Population growth in 3 years and 4 months = Population growth of three years +Population growth of 4 months

Total Population growth in 3 years & 4 months= 15,000 + 1667 = 16667

Total population = 100000 + 16667 = 116667
