Hello, 

If you wish to pursue a Bachelor in Arts degree, you will face a deduction ranging from 2.5-5%. This varies for each college, we would know about it only once the cutoff list is out. However, if you have studied Economics in class 11-12, you won't face any deductions for Eco hons. 

With your percentage and considering your quota, you may possibly get into good colleges like LSR, DCAC, IHE etc for journalism according to previous year cutoffs. For Economics, it's difficult to get through North Campus colleges. You would surely get into some decent south/off campus colleges. 

All the best!
