Answer 2

$\textbf{\underline{\underline{Answer :-}}}$

The Increase % is 25%

$\textbf{\underline{\underline{Explanation :-}}}$

Given :

The original price = Rs. 20

Increased price = Rs. 25

To find :

The Increase %

Solution :

★ We know that :

$\mathsf{Increase \: \% = \left[\dfrac{Change \: in \: Value}{Original \: Value}\right]\times 100}$

$\sf{\implies} \: Increase \: \% = \left[\dfrac{25 - 20}{20}\right] \times 100$

$\sf{\implies} \: Increase \: \% = \dfrac{5}{20} \times 100$

$\sf{\implies} \: Increase \: \%= \dfrac{500}{20}$

$\sf{\implies} \: Increase \: \% = 25\%$

$\therefore$ The Increase % is 25%
