Solution (By Examveda Team)

Selling price of grinder = Rs. 1955
$$\eqalign{ & {\text{Cost price of grinder}} \cr & {\text{= 1955}} \times \frac{{100}}{{115}} \cr & = {\text{Rs}}{\text{. 1700}} \cr & {\text{Marked price of grinder}} \cr & {\text{= 1700}} \times \frac{{100}}{{85}} \cr & = {\text{Rs}}{\text{. 2000}} \cr & {\text{Discount by the retailer }} \cr & {\text{= 2000}} \times \frac{{15}}{{100}} \cr & = {\text{Rs}}{\text{. 300}} \cr} $$
