Answer 2

Option ( C ) is correct.

Explanation :

Given

marked price of a book ( m.p )=Rs250

Selling price of the book ( s.p )=Rs 200

Let discount = d

s.p = m.p[ ( 100 - d )/100 ]

=> 200 = 250* [ (100 - d )/100 ]

=> ( 200 × 100 )/250 = ( 100 - d )

=> 80 = 100 - d

=> d = 100 - 80

=> d = 20

Therefore ,

discount ( d ) = 20%
