$x\%\text{ }more\text{ } than \text{ }y=y\dfrac{(100+x)}{100}$

We need to find out monthly income after increment from the given information.

According to the question, given income is $Rs\text{ 5000}$. Income is increased by $30%$.

Substituting $x=30$ and $y=5000$ in the above formula which is mentioned in the hint, we get

\[\begin{align}

& 30\%\text{ }more\text{ }\,than\text{ 5000}=5000\dfrac{(100+30)}{100} \\

& \text{ }=\dfrac{5000\times 130}{100} \\

& \text{ }=6500 \\

& \\

\end{align}\]

Hence new Income is $Rs\text{ }6500$

In such types of questions which involves the concept of percentages translation of information in wordings to math is to be done. Apply the appropriate formula and then solve to get the required answer.
