Rs. 60000

Explanation:

Let total amount be x
Money spent on:
Food = $\frac{1}{4} x$ $1/4x$
Rent = $\frac{1}{3} x$ $1/3x$
Other expenses = $\frac{1}{15} x$ $1/15x$
NGO = $\frac{1}{5} x$ $1/5x$
Income - Total amount spent = Remaining amount (9000)
$x$ $x$ - ( $\frac{1}{4} x + \frac{1}{3} x + \frac{1}{15} x + \frac{1}{5} x$ $1/4x+1/3x+1/15x+1/5x$ ) = 9000

$x - \frac{17}{20} x$ $x-17/20x$ = 9000

$\frac{3}{20} x$ $3/20x$ = 9000

$x$ $x$ = $\frac{9000 \cdot 20}{3}$ $(9000*20)/3$
= 60000
