First Approach

Let $x be the Marked price of an Item.

Discount =20%

Original Price after Discount = $p


\rightarrow x-(20x)/(100)=p\\\\\rightarrow (80x)/(100)=p\\\\ \rightarrow (4x)/(5)=p\\\\ \rightarrow x=(5p)/(4)

⇒Marked price of the Item
=(5p)/(4)

⇒Second Approach

If, p=Original Price of the Commodity

Discount =20%

Price after Discount


=p-(20p)/(100)\\\\=(80p)/(100)\\\\=(4p)/(5)
