This is good percentile,and your rank  approximately lies between 46582-54082 (estimating the number of students appearing for April test as 1152650). See this is your January Main result,The final result by NTA will be based on the best of two percentile of both the exams(the January and April JEE Mains test).The final April JEE Mains result will vary depending on the number of students who appeared in the test and the highest marks scored in that exam.So whether you are qualified or not can be said only after the final result after 30th April.The cutoff for qualification can be decided only then. Even the admission to various colleges will be announced after April only.

Hope this helps.
