    Answer: (1) 45
    Explanation:-
    In the Ben-diagram –

    RE: How Many Student Passed in Science and Math? If


    Total number of students in a class = 100
    Failed students = 5
    Remaining students = 100 – 5 = 95
    Passed students in maths = 80
    Passed students in science  = 60
    Passed in both subjects students = (80 + 60) – 95
    = 140 – 95 = 45.
    Thus, the answer is (1) 45.
