Hi Saurabh, greetings. COMEDK is the preliminary exam to obtain a seat in private collges in Bangalore and rest of Karnataka state. Your rank of 57439 is unlikely to get you a seat in RV College of Engineering. But please don't lose hope, participate in the counselling and  do sit in the spot round, you might get a seat. Also there is management quota, if you wish to consider that. Thank you.
