Hello shaunak ,thanks for asking question on this platform.firstly the question is that about which rank you are talking either it is category rank or all India General rank.because if we talk about category rank then if you score 170-190 marks in OBC category then you will have rank under 5000.but if we talk about general open category rank then you have to score minimum 220 marks to get rank within 5000 this rank will be your open category rank in all over India.thanks 

Hi Shaunak Deshpande, 

You must get around 215 to 230 marks out of 360 to get rank 5000 in JEE main. To predict rank based on marks, refer the below link.
