B Correct answer
Explanation

Cost price of 30 books (LCM of 5 and 6) is (30/6)*5 = Rs. 25. Selling price of 30 books is (30/5)*6 = Rs. 36. Profit = 36 - 25 = 11. Profit percent = (11/25)*100 = 44%.

AI explanation

Calculate the cost price of one book by dividing Rs. 5 by 6, which is Rs. 0.833, and the selling price of one book by dividing Rs. 6 by 5, which is Rs. 1.20. For 6 books, the total cost price is 5 and the total selling price is 7.20, resulting in a profit of 2.20. Apply the profit percentage formula: (Profit divided by Cost Price) multiplied by 100, resulting in (2.20 divided by 5) multiplied by 100, which equals 44%.
