Verified Answer
A bookseller bought 200 textbooks for 12,000. He wanted to sell them ...
Cp of 200 Books = 12000
Cp of 1 Book = 12000/200 = 60
Total Profit to be earned = Cp of 20 Books = 20 × 60 = 1200+
Profit Percentage = 1200/12000 × 100 = 10%

Calculation:

To solve this problem, we need to first calculate the cost price of each textbook and then determine the selling price needed to achieve the desired profit.

Cost Price per textbook:
Cost of 200 textbooks = $12,000
Cost price per textbook = Total cost / Number of textbooks
Cost price per textbook = $12,000 / 200 = $60

Number of books to be sold to get 20 books free:
To get 20 books free, the bookseller needs to sell 200 + 20 = 220 books.

Selling Price for 220 books:
Let the selling price per textbook be SP.
Total cost = Cost price for 200 books + Cost price for 20 free books
Total cost = 200 * $60 + 20 * $60 = $12,000 + $1,200 = $13,200

Selling price for 220 books = $13,200

Profit Calculation:
Profit = Selling price - Cost price
Profit = $13,200 - $12,000 = $1,200

Profit percent = (Profit / Cost price) * 100
Profit percent = ($1,200 / $12,000) * 100 = 10%

Therefore, the bookseller should sell the textbooks at a profit of 10% to get 20 books free. So, option 'A' (10%) is the correct answer.
