This is such a trick question. I went for C as well. How do you know when you encounter such tricky questions?
Is there a key word or something that just sets off the alarms?
you should be VERY VERY suspicious of choice (c) on problems like this one.
on this problem, if you have choice (c), you have ALL the information in the problem. IE you know the
exact numbers of both types of ticket sold.
this is ALMOST NEVER the way
official data sufficiency problems work.**
the hallmark of
official data sufficiency problems is to give situations,
the vast majority of the time (though not 100% of the time), in which
you can find the DESIRED information even though OTHER information remains unknown.
on a problem like this, if both statements together will give ALL possible information, you should not pick (c) unless you single-, double-, and
triple-check the statements to make sure that neither of them is sufficient alone.
in any case, this is NOT a "trick question" AT ALL. this is a totally routine averages question, written in the same fashion as 80-90+% of other such data suff questions.
here's another such problem:

**this is one of the many important differentiators between quality prep materials and subpar prep materials. plenty of second-class prep materials have lots and lots of questions in which you have to find
everything in the problem to get "sufficient". this is bad, because it reinforces the horrible habit of assuming that you have to find every quantity in the problem to get "sufficient".
