$\red{\underline{{ \bf Correct \: Question }}}$

• The Population of a place increased from 120000 to 150000. Find the net percentage in the the initial population.

$\red{\underline{{ \bf Answer }}}$

$\underline {\underline{{\purple{ \sf Given }}}}$

• Initial Population ➠ 120000
• Final Population ➠ 150000

$\underline {\underline{{ \purple{\sf To \: Find }}}}$

• Increased Population
• Net Percentage in the Initial Population

$\underline {\underline{{ \green{\sf Calculating \: Increased \: Population }}}}$

Formula Used :- $\underline{\underline{\boxed{ \pink{\sf Final Population - Initial Population = Increased Population }}}}$

Substituting Values

☞ $\blue{\sf 150000-120000}$

☞ $\blue{\sf 30000}$

Therefore, Increased Population is 30000

$\underline {\underline{{ \green{\sf Calculating \: Percentage \: Increased }}}}$

Formula Used :- $\underline{\underline{\boxed{ \pink{\sf \dfrac{Increased \: Population}{Initial \: Population} \times 100 \% }}}}$

Substituting Values

☞ $\blue{\sf \cancel{ \dfrac{30000}{120000} \times 100}}$

☞ $\blue{\sf 25}$

Therefore, Increased Percentage is 25 %

Answer 2

Given :

Increased = 120000 to 150000

Find :

Net percentage.

According to the question :

Let's find the decrease in the population :

= 150000 - 120000

= 30000.

Net change = 30000.

Formula :

Percentage = ( Net change / initial population ) × 100

= 30000 / 150000 × 100

= 20.

Therefore, the Net percentage = 20% .

Hope it is correct ☺
