Question

An article was purchased for 1239 including GST of 18%. Find the price of the article before GST was added? ​

Answer 1

Let the price of the article be x before adding GST.

After adding GST,

x+18% of x

$x + 0.18x \\ 1.18x$

According to the question:

$1.18x = 1239 \\ 118x = 1239 \times 100 \\ 118x = 123900 \\ x = \frac{123900}{118} \\ x = 1050$

The price of the article before adding the GST was Rupees 1050.
