Question

If your percentile rank in a group of 500 students is 84, how many persons rank lower than you?

Answer 1

If you're in the 84th percentile, that means that you rank higher than the lowest 84% of the group. Out of 500 students, 84% makes 420.

Answer 2

Answer: There are 420 students whose rank is lower than his.

Explanation:

Since we have given that

Number of students = 500

Percentile rank = 84

We need to find the number of persons whose rank lower than his.

According to question, we get that

`(84)/(100)* 500\\\\=84* 5\\\\=420`

Hence, there are 420 students whose rank is lower than his.
