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
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.
