It would be difficult to tell you about the marks as the cutoff varies every year from college to college depending on various factors such as the difficulty level of the exam, candidates appearing in the exam, number of seats available, etc.
However, you can go through the link below and check the previous year's cutoff of Karnataka college wise, category wise for reference and to have an idea about the rank required for admission
