Answer:

Hope, it helps you to understand this easily...............

Step-by-step explanation:

If we assume that the price of the phone Before the GST was added is 100 Rupees Then,the price of the phone after adding 8% GST will be=100+8=108 Rupees

Now,The price of the phone before the GST was added

=100/(100+GST%)×Selling Price

=100/(100+GST)×13,500

=100/108×13,500

=13,50000/108

=12,500(Answer)

Therefore,the price of the phone before GST was added will be 12,500 Rupees.

Answer 2

Given:

cost of mobile phone including GST =$Rs 13500$

Rate of GST = 8%

Find:

the price before GST was added​

Answer:

Thus, the original price = $Rs 12500$

Step-by-step explanation:

cost of mobile phone including GST =$Rs 13500$

Rate of GST = 8%

Let the original price = $Rs$ $x$

∴$x+8$% of $x=Rs 13500$

or $x+\frac{8x}{100}= Rs 13500$

or $x(1+\frac{8}{100} )= Rs 13500$

or $x$×$\frac{108}{100}$$= Rs 13500$

or $x= Rs 13500$×$\frac{100}{108} = Rs 12500$

Thus, the original price = $Rs 12500$
