Dear Ashish, 

Since there isnt any negative marking in AIBE, with 35 correct responses you will get 35 marks in the exam. Now, whether or not you will be declared pass in the exam will depend upon the cutoff released by the BCI, the conducting authority of AIBE. The cutoff or passing mark threshold vary from year to year. For 2019, it will be declared with the result. To give you an idea, last year for the general & OBC category, the cutoff was 38 marks of 100, while it was 33 for SC & ST. 

Hope it gives  you an idea of how the passing mark is determined in AIBE. 

The result of AIBE will be out soon. You can track the same at the URL given below.

All the best!
