Answer :
In this case, 12 out of 20 students prefer having a study hall, so the percentage is 60%.
To find the percentage of students who prefer study hall, we need to divide the number of students who prefer study hall by the total number of students and then multiply by 100.
In this case, 12 out of 20 students prefer having a study hall.
Percentage = (Number of students who prefer study hall / Total number of students) * 100
Percentage = (12 / 20) * 100 = 60%
Therefore, 60% of the students prefer study hall.
