Answer
Explanation
Let the article be worth ₹ $x$. $$\begin{aligned} & \text { C.P. }=90 \% \text { of } ₹ x=₹ \frac{9 x}{10} ; \\ & \text { S.P. }=110 \% \text { of } ₹ x=₹ \frac{11 x}{10} . \\ & \text { Gain }=₹\left(\frac{11 x}{10}-\frac{9 x}{10}\right)=₹ \frac{x}{5} . \\ & \therefore \text { Gain } \%=\left(\frac{x}{5} \times \frac{10}{9 x} \times 100\right) \%=22 \frac{2}{9} \%>20 \% . \end{aligned}$$
