10​

Answer 1

Given:

• Marked Price (MP) = Rs. 30
• Selling Price (SP) = Rs. 25

What To Find:

We have to find the discount percentage.

How to Find:

To find the discount percent we have to use the formula,

$\sf{Discount \: \% = \dfrac{Marked \: Price - Selling \: Price}{Marked \: Price} \times 100}$

Solution:

Using the formula,

⇛

$\sf{Discount \: \% = \dfrac{Marked \: Price - Selling \: Price}{Marked \: Price} \times 100}$

Substitute the value,

⇛

$\sf{discount \: \% = \dfrac{Rs.\: 30 - Rs. \: 25}{ Rs.\: 30}\times 100}$

Subtract the numerator,

⇒

$\sf{Discount \: \% = \dfrac{Rs. \: 5}{ Rs.\: 30}\times 100}$

Cancel 5 and 30,

⇒

$\sf{Discount \: \% = \dfrac{1}{ 6}\times 100}$

Divide 100 by 6,

⇒

$\sf{Discount \: \% = 16. 66 \: \%\: approx}$

Therefore, the discount percentage is 16.66 % approx.
