Difficulty:

(N/A)

Question Stats:

60% (01:01) correct 40% (00:28) wrong based on 4 sessions
Amy's grade was the 90th percentile of the 80 grades for her class. Of the 100 grades from another class, 19 was higher than Amy's and the rest was lower. If no other grade is the same as Amy' grade, then Army's grade was what percentile of grades of two class combined.

72nd
80th
81st
85th
92nd

Any idea folks what could be the answer please and how to solve?

People above Amy in her class =10/100*80=8
People above Amy in other class=19
Total people =27
Percentile above=27/180*100=3/20*100=15

Hence 85

If you're into weighted average & stuff-

Her grade falls in the 81st percentile in the other class as in that class of 100 19 had higher grades than Amy's.

90 (80/180) + 81 (100/180) =85
