The practice questions form the OG are the best, if you finish those then these 10 critical reasoning practice questions should help.

5 key strategies for tackling critical reasoning questions in the GMAT.

Perhaps a simpler way to look at why both statements together are sufficient is to add both equations together You know X - 3Y > 0 and 4Y - X > 0 so (X - 3Y) + (4Y - X) > 0 + 0 Simplifying both sides gives you Y > 0 If Y > 0 and X - 3Y > 0 then X > 0 Since X and Y are both greater than 0, then X + Y > 0, so both statements together are sufficient. See this data sufficiency tutorial for more help solving these types of questions.

The total number of tickets was 7,000 but 80 remain unsold so the total number sold was 6,920. The tickets were sold at an average price of $10. The total value of tickets sold was 6,920 x $10 = $69,200 so the answer is B. For more help with this type of question see this GMAT word problems tutorial.
