Hi

As per last year cutoffs, BIT Durg does not consider Female Ranks secured in CG PET. Please provide your CG PET 2019 Common Rank to know which colleges or branch you can get accordingly. Also, you can check that yourself by tallying from the previous year cutoffs. 

And as you have mentioned, you obtained 75% in 12th Board Examination, you are eligible to take admission in BIT Durg.

Best of Luck.

Hope this helps.

Cheers!
