Explanation:
Let [tex]x =[/tex] the original amount of money. If he lost 1/5 of it, then he only has 4/5 left. Then he spent 65% of it which means that he only has 35% of the 4/5ths of the money left. Therefore, we can set up the equation as
[tex]0.35(\frac{4}{5}x) = \text{Rs}\:441[/tex]
[tex]\Rightarrow x = \frac{5}{4}(\text{Rs}\: 441/0.35) = \text{Rs}\: 1,575[/tex]
