Hii Siddhant!
Sorry dear, but you haven't mentioned the name of the examination for which you want to know the number of questions from each subject. You need to restructure your question and ask again in order to get correct information from our side. If you are talking about class 9th final exams then, let me tell you that, in general, the question paper will contain 4 sections A, B, C, D. The marks will vary as 1 or 2 marks questions for section A; 3 marks questions for  section B; 4 marks question for section C; and 5 marks questions for section D. But, it may vary depends on different education boards.
Hope you understand.
Good luck!
