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

Step-by-step 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

\(\dfrac{84}{100}\times 500\\\\=84\times 5\\\\=420\)

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