Well praveen according to previous years cut off rank analysis which is subjective as cut off ranks change every year depending upon current years level of difficulty of examination and no of candidates applying for ece and aeronautics specifically but if we look at previous years cut off then

• for aeronautics you probably have decent chances of getting it in acharaya as cut off rank for aeronautics in acharaya ranges between 51401 to 60625 
• for ece its highly subjective as cut off rank for ece at acharaya changes every year drastically so you might/might not get ece will depend entirely on current years merit list as cut off rank was 18072 in 2017 and 56575 in 2018 so will depend completely on current year.
