Question

A shopkeeper gives 10% discount on a TV set whose list price is Rs. 16,500. Find the amount which a customer has to pay for buying the TV set if the rate of GST is 18%.

Answer 1

Step 1: Given terms:

The list price of TV Set $=\mathrm{Rs}.16,500$

Discount$=10\%$

Rate of GST$=18\%$

Step 2: Calculate the GST amount:
Since, the shopkeeper gives a $10\%$discount on a TV set whose list price is $\mathrm{Rs}.16,500$.

Cost price for the customer is computed as:

$$\begin{gathered} \mathrm{C}.\mathrm{P}=16,500-\left(\frac{10}{100}\times 16,500\right) \\ \Rightarrow \mathrm{C}.\mathrm{P}=16,500-1,650 \\ \Rightarrow \mathrm{C}.\mathrm{P}=\mathrm{Rs}.14,850 \end{gathered}$$
GST on $\mathrm{Rs}.14,850$ at the rate of$18\%$ computed as:

$\begin{array}{rcl}\mathrm{GST}& =& 14,850\times \frac{18}{100}\\ \therefore \mathrm{GST}& =& \mathrm{Rs}.2,673\end{array}$

Step 3: The amount to be paid by the customer:

$\begin{array}{rcl}\mathrm{Amount}& =& 14,850+2,673\\ \therefore \mathrm{Amount}& =& \mathrm{Rs}.17,523\end{array}$

Hence, the customer has to pay$\mathrm{Rs}.17,523$ for buying the TV set.
