The original price p of an item less a discount of 20%

Answer 1

Like 10% maybe your subtracting ight? message back so i can help

Answer 2

⇒First Approach

Let $x be the Marked price of an Item.

Discount =20%

Original Price after Discount = $p

$\rightarrow x-\frac{20x}{100}=p\\\\\rightarrow \frac{80x}{100}=p\\\\ \rightarrow \frac{4x}{5}=p\\\\ \rightarrow x=\frac{5p}{4}$

⇒Marked price of the Item $=\frac{5p}{4}$

⇒Second Approach

If, p=Original Price of the Commodity

Discount =20%

Price after Discount

      $=p-\frac{20p}{100}\\\\=\frac{80p}{100}\\\\=\frac{4p}{5}$
