Hello,

JEE Mains total marks is 300. Mathematics 100, physics 100 and chemistry 100. You have to secure 100 marks in total to qualified. But if you want to know minimum marks each subject then it should be 35 . You have to score 35 marks in each subject then you will qualified in JEE Mains examination. But you have to target more marks then you can achieve good marks and your rank will be better. So study hard dear.

All the best.
