What should the percentile ranks be for each of these records and is there a MySQL query I can run to calculate the percentile?

id    score   cumulative_score     percentile
1     100     100                  ?
2     50      150                  ?
3     25      175                  ?
4     25      200                  ?
5     10      210                  ?
