Question

I purchased a hair -dryer for Rs $5400$ including $8$%VAT. Find the price before VAT was added.

Answer 1

Price after $8\%$ vat$=5400$

If the initial price$=x$

vat$=8\%$

Final price$=x+\frac{8x}{100}=x\left(\frac{108}{100}\right)$

Given:- $\frac{108x}{100}=5400$

$\Rightarrow x=\frac{5400\times 100}{108}=5000$

$\therefore$ The price of hair dryer before VAT was added $=5000$Rs.
