    Answer: 23

    Step-by-step explanation:

    let x=no. of students in both classes

    no. of students in anatomy = 34

    no. of students in anatomy only = 34 - x

    no. of students in physics = 37

    no. of students in physics only=37-x

    48 = 34-x + 37-x + x

    48 = 34 - x + 37

    48 = 71 - x

    x = 71 - 48

    x = 23

    Therefore the number of students in both classes are 23
