The passing percentage is decided by the Council/University under which you are studying the course. In general, the passing marks for the Nursing is 30% of the score. So if you have 30 in Nutrition then you need to score above 9 in Nutrition and as you have 35 in Biochemistry so you need to score above 11 marks. The aggregate marks in Biochemistry and Nutrition (if accounted together) then you need to score above 22.5 marks out of 75 in order to pass the examination.

For the passing percentages, you can visit the website of your counselling in order to know more.
