Answer: 900 people.
Explanation:
If you are in the 55th percentile then that means that you scored better than or at least as good as 55% of people who took the GRE because a peecentile is a measure that states the position of a number in a data set as a percentage.
If calculating how many people had a mark at least as high as your own, that means those people who scored higher than or at least what you scored.
If you scored higher than 55% then that means that,
= 100 - 55
= 45%
45% scored at least as high as you.
2,000 took the test so 45% will be
= 2,000 * 45%
= 900 people.
900 people scored at least as high as you.
