Explanation / Answer

Since the image is not properly given I can't answer the whole question but let me explain you the concept behind %tile and then what so ever will be the % you will be able to answer properly

So., She scored 87%tile in Verbal i.e. (100-87=13) = 13% of the students scored more than her and she scored better than 87% of the students

Just like that if she scored x% i math then she scored better than (100-x)% of students and x% students didn't do better than her.

FYI Formula for percentile rank:

Percentile rank = Number of scores below x/n * 100

Here x out of a set n scores are considered where x is not included.
