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
