Question 1194147
.



            Let me insert  (contribute)  my  two cents  to this solution.



<pre>
If we are given that "Rick scored lower than 1132 of the 12,800 students", then all that we can state is that his percentile is lower than 


    100% - 8.84375% = 91.15625%.



<U>ANSWER</U>.  All what we can derive from the given part is that Rick's score 

         is lower than 91.15625%.
