A book is sold at a discount of 32% and an additional discount of 25% is allowed on cash payment. If Ramesh purchased the book by paying Rs. 2,550 in cash, find the marked price of the book.

Let the marked price of the book be MP.
The successive discounts are 32% and 25%.
The final selling price (SP) can be expressed as:

SP=MP×(1−
