Question

You went to a store and purchased an iphone worth 72000. The invoice mentioned GST as 18%. How much you would have paid if the GST charge by the Government for this item was 28%?​

Answer 1

Answer:

28% of 72000

28/100*72000=20160

(including revised GST) 20160+72000=92160

Answer 2

Given,

The amount paid for the iPhone$\[ = 72000\]$

The GST is applicable in the first case$\[ = 18\% \]$

The GST is applicable in the second case$\[ = 28\% \]$

To find,

The cost price of the iPhone.

Solution,

The price of iPhone without the GST applicable

$\[\begin{array}{l} \Rightarrow 72000 - \left( {\frac{{18}}{{100}} \times 72000} \right)\\ \Rightarrow 72000 - \left( {18 \times 720} \right)\\ \Rightarrow 72000 - 12960\\ \Rightarrow 59040\end{array}\]$

Therefore, the new price of the iPhone along with the new GST

$\[\begin{array}{l} \Rightarrow 59040 + \left( {\frac{{28}}{{100}} \times 59040} \right)\\ \Rightarrow 59040 + \left( {0.28 \times 59040} \right)\\ \Rightarrow 59040 + 16531.2\\ \Rightarrow 75571.2\end{array}\]$

Hence, the cost price of the iPhone is Rs$\[75571.2\]$ .
