Answer 2

Answer:

number of students who study both Mathematics and Physics = 10

Step-by-step explanation:

Total Students = T = 50

Study Mathematics = M = 40

Study Physics = P = 20

Study both Mathematics & Physics = M ∩ P

T = M + P - M ∩ P

=> 50 = 40 + 20 - M ∩ P

=> M ∩ P = 10

number of students who study both Mathematics and Physics = 10
