 |
|
Amy's grade was the 90th percentile of the 80 grades for her class. Of the 100 grades from another class, 19 were higher than Amy's and the rest were lower. If no other grade was the same as Amy's grade, then Amy's grade was what percentile of the grades of the two combined?
A. 72nd
B. 80th
C. 81st
D. 85th
E. 92nd
Please Help....
Thanks. |

I go with D 85th
90% percentile out of 80 means 8 students were above her.
out of another 100 students 19 were above her.
total number of students above her out of 180 students are 27.
thus Amy grade was 153/180 = 85th percentile.
Hope that helps... |
