Can someone help me with this percentile question?

Jane is one of 50 students to take a standardized math test that includes 100 multiple-choice questions. If she has the highest score of any student with a raw score of 87, what is her percentile score?

    There seems to be more than one definition of percentile.  One calls it the percent of scores which are less than the given score, so it would be 49/50 • 100 = 98th percentile.

    Another calls it the percent of scores less than or equal to the given score, which would be 50/50 • 100 = 100th percentile.

    This has confused me ever since taking statistics in college.  Maybe someone else will give a better answer...
