abidemiokin

The number of students in the class​ is 36 students

Let the total number of people that read physics be n(P)

Let the total number of people that read Mathematics be n(M)

Let the number of people that read both subjects be n(PnM)

The total number of students in the class will be represented as n(PUM)

Based on the set formula

n(PUM) = n(P) + n(M) - n(PnM)

n(PUM) = 24 + 21 - 9

n(PUM) = 45 - 9

n(PUM) = 36

Hence the number of students in the class​ is 36 students
