Universal Set = Whole class

Let the number of students of whole class be represent by U.

Set A = Number of students who secured more than 50% in math.

=> Set A¹ or Complement of A = Number of the students remaining in U.

=> Set A¹ = U - Set A

rajk123654987: See munna143, the question has only elements type form. If the question has number of students who are in the class, then you can have a numerical answer. For this question it is absent and hence only equation form is available
