Hello Anurag,
To be eligible for B.Com Honours you need to clear maths in your 12th Boards. Without maths you will not be offered a seat for the B.Com Honours course in DU or any other university. However you will get admissions in B.Com general without maths if you fulfill the other eligibility criterias of the college you are seeking admission to.
Hope this helps.
All the best!
