Question

The price of a washing machine, inclusive of Sales Tax, is Rs. $13,530$. If the Sales Tax is $10\%$, find its basic (cost) price.

Answer 1

Let the basic cost is Rs. $x$

Then according to the question, we have

$\Rightarrow x+10\%ofx=13530$

$\Rightarrow x+\frac{x}{10}=13530$

$\Rightarrow \frac{11x}{10}=13530$

$\Rightarrow x=\frac{135300}{11}$

$\Rightarrow x=$ Rs. $12300$

Thus, the basic cost is Rs. $12300$.
