<p>Since QB is a fixed value given as an integer, we just need to calculate QA and compare it. We can follow a process to find the number of multiples within an interval:</p>
<ul>
<li>Since $\frac{100}{11} \sim 9.09$ we know that the first multiple of $11$ in the interval will be the $10th$ multiple of $11$.</li>
<li>Since $\frac{500}{11} \sim 45.45$ we know that the last multiple of $11$ in the interval will be the $45th$ multiple of $11$.</li>
<li>So, there will be $(45-10)+1=36$ multiples of $11$ in the interval. We added $1$ because both endpoints of the range need to be included.</li>
</ul>
<p>So, QA is $36$ and QB is also $36$, so they are equal.</p>
<p>Therefore, the answer would be <span style="color:#27ae60;">C</span>.</p>
