${\fbox{\fbox{\huge\sf\purple{AnSwER}}}}$

Students who donated blood = 60% of the students

Therefore,

Students who did not donate blood = (100 - 60)%

= 40% of the total students

Also, number of students who did not donate blood = 480

Therefore,

40% of the total students = 480

=> Total students = 480 × 100/40

=> Total students = 1200 students

Hence:-

There are 1200 students in the school.

students who did

not donated blood=(100-60)%=40%

no. of students did not donated blood=480

40% of the total students =480 => total students=480x100/40

=> 1200 students
