Answer:
Total no. of students=60
No. of students who study physics=27
No. of students who study Mathematics=42
Now since each student studies at least one of these subjects, let us suppose that the no. of students who study both these subjects as x
From this we see that
No. of students who study only physics=27-x
No. of students who study only maths=42-x
Now simply adding,
(27-x)+x+(42-x)=60
From the above equation you should get the answer as 9
