As per the previous year trends, you stand a good chance of getting admission into government colleges.
The general ccategory cutoff tfor qualifying the exam is 50 percentile which means 350 marks. and you have scored a decent rank so i believe yes you can get into government colleges.
To predict the college you can use our college predictor tool. Here is a link for the same  -
