The above problem doesn’t really test understanding of lots of concepts (other than the definition of median, mode). Rather, you have to use all of the information the problem gives you to come up with constraints for x and y, which you probably haven’t done yet. Ask yourself, “where have I used the fact that 80 is the only mode?” You should end up with a few inequalities relating x and y.
