⇒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}

These people need to divide 20 liters of water among themselves, so we just use division.
