Solution (By Examveda Team)

According to the question,
$$\eqalign{ & {\text{Selling price}} \cr & = \frac{8}{5} \times {\text{Cost price}} \cr & \frac{{{\text{Selling price}}}}{{{\text{Cost price}}}} = \left. {\frac{8}{5}} \right\}{\text{3 gain}} \cr & {\text{Gain}}\% = \frac{3}{5} \times 100 = 60\% {\text{ }} \cr} $$
