hii Sawan ,

As you not mentioned your category here . we can not say that admission will happen or not . You can check  last year cut off of BHU UET.  from link given below . After checking cut off you can predict your admission according to cut off . But according to your marks and  rank there is the Chance of admission is very few. You can wait for 2nd or 3rd round counciling . But my suggestion apply some other college like DU and state university for Economics honours . 

For cut off - https://www.google.com/url?sa=t&source=web&rct=j&url=https://university.careers360.com/articles/bhu-uet-cut-off/amp&ved=2ahUKEwiws7vBuvfiAhWRbn0KHa57CV4QFjACegQIDBAJ&usg=AOvVaw1RMUsy_2FX5LSZdBpbcioq&ampcf=1

Hope it helps!!
