Answer
$420
Work Step by Step
The discount on television’s price is 20%. So, the percentage of the original price at which it was bought is
$100-20=80%$
Consider the equation to calculate the price at 80%
$x\times \frac{80}{100}=336$
Here, x is the price before reduction.
Now, solve the above equation
$\begin{align}
& x\times \frac{80}{100}=336 \\
& x=336\times \frac{100}{80} \\
& =\$420\end{align}$
Thus, the television’s price before reduction was $420.
