Question

Out of her total monthly salary, Tanvy spends 30% on house rent and 60% of the rest on household expenditure. If she saves $Rs.10500,$ what is her total monthly salary?

Answer 1

Let x be Tanvy monthly salary.

Here House rent $=30\%$ of x

$=\frac{30}{100}x$

$=\frac{3x}{10}$

Household expenses $=60\%$ of x

$=\frac{60}{100}x$

$=\frac{6}{10}x$

$\therefore$ Total saving$=10500$

$\Rightarrow x-(\frac{3x}{10}+\frac{6}{10}x)=10500$

$\Rightarrow x-\frac{9}{10}x=10500$

$\Rightarrow \frac{x}{10}=10500$

$\Rightarrow x=1,05,000$

$\therefore$ Tanvy monthly salary $=$Rs. $105000$.
