**Steve**, Monday, March 25, 2013 at 10:35amHard 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
