Question

Navita earns $Rs.16000$ per month. She spends $\frac{1}{4}$ of her income on food, $\frac{3}{10}$ of the remaining on house rent and $\frac{5}{21}$ of the remaining on education of her children. How much money is still left with her?

Answer 1

Navita's income $=Rs.16000$

Income spent on food $=\frac{16000}{4}=Rs.4000$

Remaining amount $=16000-4000=Rs.12000$

Amount spent on house rent $=\frac{3}{10}\times 12000=Rs.3600$

Remaining amount $=12000-3600=Rs.8400$

Amount spent on education of children $=\frac{5}{21}\times 8400=Rs.2000$

Remaining amount $=8400-2000=Rs.6400$

Hence, amount left with her $=Rs.6400$
