Hey 

Your non maths background at +2 level doesn't resists you from your admissions in Mumbai University. You are totally eligible for the B.com course .

Dear Student,
I would like to tell you that YES you are eligible for taking admission in B.COM in Mumbai University. It does not require you to have to have maths as a mandatory subject in class 12th. The basic criteria is to have a minimum of 50% in Higher Secondary. So you can easily go for any college of your choice.
All the best. I hope this was helpful to you.
