Given: Neelm's annual income = Rs.  288000
Her annual savings = Rs. 36000
Her annual expenditure = Annual income- annual Savings
=Rs 288000-Rs. 36000

=Rs. 252000 \\
The ratio of her savings to her expenditure

$\\ \Rightarrow \frac{\text { Savings }}{\text { Expenditure }} \\\\ =\frac{\text { Rs. } 36000}{\text { Rs. } 252000}=\frac{1}{7}\Rightarrow 1: 7$
