No, normally it's not required but some colleges take there they have Maths as a subject but if you can secure marks with remaining subjects then you can get an admission but several colleges and universities also give you liberty to opt for the course without having Maths.

First of all you should try for B.Tech if not possible then BCA where you should majorly focus on competitive coding or development so that you can easily get a job of 30-50k and then you should think of specialisations like machine learning AI data Science which can give a big boost or you can go for MBA if you have interest in that side.
