Answer (as printed):
Explanation
Let the total number of votes enrolled be $x$. Then, Number of votes cast $=75\%$ of $x$. Valid votes $=98\%$ of ($75\%$ of $x$). $75\%$ of $[98\%$ of $(75\%$ of $x)]=9261 \Leftrightarrow \left(\frac{75}{100}\times\frac{98}{100}\times\frac{75}{100}\times x\right)=9261 \Leftrightarrow x=\left(\frac{9261\times 100\times 100\times 100}{75\times 98\times 75}\right)=16800$.
