Hi Sai tarun 

First of all your question is not correct I mean it has not asked in the way that should be asked and I didn't understand the question that is asked by you as you have not asked your doubt properly so it doesn't make sense. If you are asking about any colleges with computer science branch and mechanical engineering branch then you should have mentioned the rank that is scored by you so go through the below link for knowing the colleges in which you can get seat with the stream .
