Question

How to find MP when discount percent and SP are given​

Answer 1

Given:

Consider the discount percent and SP are given​.

To find:

The MP.

Solution:

Let x% be the discount percent Then

`SP=MP-x\%\text{ of }MP`

`SP=MP-(x)/(100)MP`

`SP=\left(1-(x)/(100)\right)MP`

`SP=\left((100-x)/(100)\right)MP`

Multiply both sides by 100.

`100SP=(100-x)MP`

Divide both sides by
`(100-x)`.

`(100)/(100-x)SP=MP`

Therefore, the formula for MP is
`MP=(100)/(100-x)SP`, where x is the discount percentage.
