The sale price of a TV set including VAT is Rs 27000.

Let the list price of the IV set be Rs $x$.

$\mathrm{VAT}=8 \%$ of Rs. $x$

$=\operatorname{Rs} \cdot\left(x \times \frac{8}{100}\right)$

$=\operatorname{Rs} \cdot \frac{8 x}{100}$

$\therefore$ Price including VAT $=\mathrm{Rs} .\left(x+\frac{8 x}{100}\right)$

$=$ Rs. $\frac{108 x}{100}$

Now, $\frac{108 x}{100}=27000$

$\Rightarrow x=\left(27000 \times \frac{100}{108}\right)$

= 25000

Hence, the list price of the TV set is Rs 25,000.
