25%

20%

30%

10%

- Let's assume the marked price (MP) of the book is $100.

- The bookseller buys it at a 25% discount, so the cost price (CP) is $75.

- To gain 20% on the sale, the selling price (SP) should be SP = CP × 1.20.

- Thus, SP = $75 × 1.20 = $90.

- The original marked price is $100, but the desired SP is $90.

- The discount offered by the bookseller is: ((MP - SP) / MP) × 100.

- Plugging in the values: ((100 - 90) / 100) × 100 = 10%.

The correct answer is Option 4: 10%.
