It is given that maximum no of students has chosen Engineering and technology i.e. 40% which is equivalent to 400 students. 30% have chosen IT which is around 300 students, 20% have chosen physics i.e. 200 students which are half of Engineering and technology. While the remaining students has chosen  

chemistry i.e. 10% which is equivalent to 100 ( one-fourth of Engineering).
