We should consider that the all out yearly premium paid by Mr. Pankaj be \[Rs.\text{ }X.\]
Then, at that point, from the inquiry
\[\begin{array}{*{35}{l}}
18percent\text{ }of\text{ }X\text{ }=\text{ }SGST\text{ }+\text{ }CGST \\
18percent\text{ }of\text{ }X\text{ }=\text{ }1800\text{ }\left[ as\text{ }SGST\text{ }=\text{ }CGST \right] \\
\end{array}\]
Along these lines, \[18/100*\text{ }X\text{ }=\text{ }1800\]
\[X\text{ }=\text{ }Rs.\text{ }10,000\]
Consequently, the all out yearly premium paid by him for the arrangement is \[Rs.\text{ }10,000\]
