C Correct answer
Explanation

Cost of N toys from first batch: Rs (9/12)*N = 0.75N. Cost of N toys from second batch: Rs (9/18)*N = 0.5N. Total cost = 1.25N for 2N toys. Selling at Rs 15 per 18 toys = Rs 5/6 per toy. Revenue = 2N * 5/6 = 5N/3. Profit = 5N/3 - 5N/4 = 5N/12. Profit% = (5N/12)/(5N/4) * 100 = 33.33%.
