Hello, Aspirant
After , your 12th/intermediate exams completed  with degree of bio and maths you can go for B.Tech biotechnology. Eligibility for this course is for  B.Tech biotechnology is seen in most of the top universities is Pass with 60% aggregate marks in 10+2 (with Physics, Chemistry, English and Mathematics or Biology or Biotechnology).
Biotechnology course is all about using concepts of Biology for tweaking and modifying biological systems,  so that they can be used in Engineering and Technology related applications to improve and enrich various sectors such as healthcare, food processing, agriculture, pharmaceuticals etc and solve problems arising in these sections. There other biology courses and pharmacy, medical etc., but this biotechnology is best for your intermediate course what you mentioned in the question.
After your B.Tech degree,  you can find jobs in pharmaceutical companies, research labs, biotech companies like Life Cell, Reliance Biotech, and many others and institutions in India.  Here you develop the above  sectors in various forms.There are various industries that are engaged in developing and researching biological systems and chemical industries.
Since India is still developing in nature.  it is highly recommended that you do your B.Tech in a reputed institution for good campus placements and job opportunities. If your university is not having reputation then the placements level is zero for you.
I would like to recommend you some best universities for biotechnology course in b.tech such as:
