percentage increase of population per year?
10%
15%
20%
25%​

Answer 1

Answer:

Increase in 10 years= 350000-175000 = 175000

Increase % = 175000/175000 ×100 = 100%

Increase % in 1 year = 100/10 = 10%

Answer 2

10% is the correct answer

Given: Increase in population

To Find: Percentage increase per year

Solution:

Net Increase in population,

350000 - 175000 = 175000

Now,

Total percentage increase in population,

= 175000×100/175000 = 100%

There are 10 years in a decade

Percentage increase per year = 100/10 = 10%

Therefore, 10% is the correct answer.
