$\sf\red{Given :-}$

a man loses 20% of his money after spending 25% of the remainder . He has rupees 480 left what is the amount of money he originally had ?

$\sf\red{Solution :-}$

$\rm\blue{Let\:the\:maximum\:marks\:=\:x}$

Then,

${\sf\frac{x \: \times \: 20}{100} + 30 = \frac{x \: \times 32 }{100} - 42}$

${\sf\frac{32x}{100} - \frac{20x}{100} = 30 + 42}$

${\sf\frac{12x}{100} = 72}$

${\sf x = \frac{72 \: \times \: 100}{12} = 600}$

${\blue{\therefore\rm{Passing\:marks\:=}}}$

${\sf\frac{60 \: \times 20}{100} + 30 = 120 + 30 = 150}$

$\rm{\blue{\%\:{of\:Pass\:marks\:=}}}$

${\sf\frac{150}{600} \times 100 = 25\%}$
