Hello,

Firstly, let me tell you that these factors depends upon many factors like the number of candidates appearing for the exam also the number of candidates attended the exam.

Mainly each and every competitive exams keep their eligibility criteria as to score 50% if from general and 45 - 40% if from reserved category to get admission.
