How much percentile should have in jee main to join in sastra?

Sastra University has a different admission procedure it doesn't give admission only on the basis of Jee Mains, the merit list is prepared on the basis of your board percentage as well as your jee marks and you need to have more than 90% in boards and more than 100 marks in mains to get admission in your desired branch,
70% seats are reserved for the merit list which is prepared by jee main marks and board percentage and the rest 30% seats are reserved for boards percentage only but the competition their is tough.
Hope it helps.
Thank you.
