Population of the village of gavas is 10,000 at this moment. It increases by 10% in the first year. However, in the second year, due to immigration, the population drops by 5%. Find the population at the end of the third year if in the third year the population increases by 20%.
Answers
Answer:
The total population at the end of the years is 12540 .
Step-by-step explanation:
As given
Population of the village of gavas is 10,000 at this moment.
It increases by 10% in the first year.
10% is written in the decimal form
= 0.10
10% increases = 0.10 × Population of the village
= 0.10 × 10000
= 1000
Total population at the end of first year = Population of village + 10% increases
= 10000 + 1000
= 11000
As given
However, in the second year, due to immigration, the population drops by 5%.
5% is written in the decimal form
= 0.05
Decreases 5% = 0.05 × Total population at the end of first year
= 0.05 × 11000
= 550
Total population at the end of second year = Total population at the end of first year - Decrease 5% .
Total population at the end of second year = 11000 - 550
= 10450
As given
if in the third year the population increases by 20%.
20% is written in the decimal form
= 0.20
Increases 20% = 0.20 × Total population at the end of second year
= 0.20 × 10450
= 2090
Total population at the end of third year = Total population at the end of second year + Increases 20%
= 10450 + 2090
= 12540
Therefore the total population at the end of the years is 12540 .
Answer:
12540
Step-by-step explanation:
Population = 1000
Increased by 10 % in First Year
10% increase = (10/100) * 10000 = 1000
Population after First Year = 10000 + 1000 = 11000
Decrease by 5% in second year
5% decrease = (5/100) * 11000 = 550
Population after 2nd Year = 11000 - 550 = 10450
20% increase in 3rd Year
20% increase = (20/100) * 10450 = 2090
Population After third Year = 10450 + 2090 = 12540
Population after three years = 12540
