Question

The population of a city increased in two years from 25,000 to 30,000: find the increase percent during the time.

Answer 1

30000 - 25000
=5000
increase of 5000
so increase% = 5000/25000 ×100
= 5×4
=20%

Answer 2

The correct answer is 20%.

Given: The population of a city increased in two years from 25,000 to 30,000.

To Find: Increase percent during the time.

Solution:

The increase in population in 2 years = Final population - initial population

= 30000-25000

= 5000

Percentage increase in population = $\frac{Increase}{Initial population} *100$

= $\frac{5000}{25000}*100$

= $\frac{1}{5} *100$

= 20%

Hence, the percentage increase in population during the time is 20%.
