Answer:

$Initial \:money =Rs\:150$

Step-by-step explanation:

$Let \: initial \: money \: =Rs\:x$

$\frac{2}{5} \:of \: initial\\money = \frac{2x}{5}$

$Money \:left = Rs\:90$

$\implies x-\frac{2x}{5}=90$

$\implies \frac{5x-2x}{5}=90$

$\implies \frac{3x}{5}=90$

$\implies x = 90\times \frac{5}{3}\\=30\times 5\\=Rs \:150$

Therefore,

$Initial \:money (x)=Rs\:150$
