1. Answer:

   Lets take the original price to be = x

   Price after discount = 180

   Discount = 10%

   First we minus the discount from 100; so, 100-10=90

   = × x = Original Price

   = × x = 180

   = × x = 180

   = x = = 180

   = x = Rs. 200

   ∴ The original price of the book is Rs. 200.

2. CP = 10/100×180 = 18 rupees; CP = Discount + Present price = 18+180 = 198 rupees. Thefore 198 rupees is the answer.
