B.A Economics

Karaikal campus offers BBA (Honours) and B.Com (Honours) under its NEP-aligned undergraduate programmes, but it does not list B.A. (Honours) Economics among its UG offerings at that location.

The Department of Economics exists at the main Pondicherry campus, offering B.A. (Honours) Economics, M.A., and Ph.D., but this programme is not available at Karaikal campus.

There is several Universities which offer B.A Economics with international Relations. Some examples for government Universities are Delhi University colleges like Hindu college, st Stephens college, sri Ram college of commerce and for more focused look on IR consider Jawaharlal Nehru university, jamia millia islamia.The average fee ranges 500 to 80000.Hostel facilities are available in these colleges.

Yes the Gargi college allow to pursue B.A.Economics Hons without maths in class 12th many of the University doesn't allow the B.A. Economics without maths but the Gargi college allow it without mathematics in class 12th so if any students is pass 12th class without mathematics then they are eligible in Gargi University for B.A. Hons

For BA economics hons. Without having a maths background in 11th and 12th I think you can clear some competitive exam and get into DELHI UNIVERSITY and if you are thinking of private one you can definitely go to chandigarh University and also hyderabad university. 

Chidambaram College, Bishop Heber College - [BHC], Thiruchirapalli, Queen Mary's College, Virudhunagar Hindu Nadars' Senthikumara Nadar College, Alagappa Government Arts College, Ethiraj college for women, This  are  the top college in Tamilnadu for BA Economics.
