in a class of 60 students,the number of students who pass biology is 6 more than the number who pass chemistry.every student passed at least one of the two subject.how many pass in only biology.how many pass in only chemistry.

  • MATHS -

    Hard to say. All we know is that if c students pass chemistry only, and x pass both,

    c + (c+6) + x = 60
    2c = 54-x
    c = 27-x
    and x>0, so
    c<27

    So, we could have

    26 pass chemistry only,
    32 pass biology only,
    2 pass both

    all the way down to
    0 pass chemistry only,
    6 pass biology only,
    54 pass both
