Question

Tamara's mark is higher than 63% of the class. a) What percentile does she fall into? b) How many students score less than she does? c) What is Tamara’s score?

Answer 1

(a)   She is falling into 63^rd percentile.

(b)  Let the number of students be A.

i = (P/100) x N

 = (63/100) x A

 = 0.63A

0.63A students score less than she does.

(c) We can calculate score from percentile. We need the score of Tamara at percentile rank which is not given in the question.
