Answer 2

$\huge {\blue {\sf {\underline {\underline {Solution}}}:-}}$

Let assume that Cost Price of an article = Rs 1.

$Gain\% = \frac{Selling \: Price \: - \: Cost \: Price}{Cost \: Price} \times 100\% \\ \\ Gain\% = \frac{21 - 18}{18} \times 100\% \\ \\ Gain\% = \frac{3}{18} \times 100\% \\ \\ Gain\% = \frac{1}{6} \times 100\% \\ \\ Gain\% = \frac{1}{3} \times 50\% \\ Gain\% = 16\frac{2}{3}\%$
