its all comparative and besd upon your luck 

barch provides higher packages than bsc but recquires lots of hard works as well as there is not so much demanding job opportunities in india (which is decreased in paste few years) but yes it provides highest packages .now if you want to do maths hons. then hansraj would be better than ladyshree ram as it has good ranking .if you chose maths then you can get teaching, civil or bank sector jobs . you should follow what is your passion as barch or bsc has its own ups and downs 

(my view: i will chose bsc maths as there is more ups and downs in barch as compared to bsc ) please research job opportunities of your own)
