  $91$ .

Explanation of Solution

Given information:

Out the $100$ test scores, there are $9$ scores greater than $93$ .

Calculation:

A percentile rank of a data value is the percentage of data values that are less than and equal to that value.

Out the $100$ test scores, there are $9$ scores greater than $93$ . This mean there are $\left(100-9\right)=91$ test scores less than or equal to $93$ .

Therefore percentile rank of $85$ would be $\frac{91}{100}=91\%$ .
