HI, 

Before giving your answer i would like to tell you how the cutoff is being calculated and its factors. 

Cut  offs are determined based on the following factors for admission to BTech programmes

• Number of candidates applying for the exam
• Total number of candidates appearing in JEE Main exam
• Total number of BTech seats available
• The difficulty level of the entrance exam
• Previous year’s AP EAMCET cutoff trends

Since buy comparing the eamcet data of 2016,2017and 2018 there no such difference in cutoff as in three year around 5065-5100 candidates are registered from general category and cut off varies as 81-115

While for OBC around 60000 candidates are registered with cutoff 49-70

For st/sc cuttoff varies to 27-50.
