Rishi bought a magazine for Rs. 784 which included a GST of 12%. What was the price of the magazine before GST was included?

Let the price of the magazine before GST was included be 'x'.

GST amount = Price before GST x 12%

Then, $\mathrm{x}+(\mathrm{x}\times 12\%)=784$

$\mathrm{x}+\left(\frac{\mathrm{x}\times 12}{100}\right)=784$

$\mathrm{x}+(0.12\mathrm{x})=784$

$1.12\mathrm{x}=784$

$\mathrm{x}=\frac{784}{1.12}=700$

Therefore, the price of the magazine before GST included was Rs 700.
