Question

an article was purchased for rupees 1239 including GST of 18 % find the price of the article before GST was added

Answer 1

Find the percentage with GST:

100 + 18 = 118%

Find 1%:

118% = Rs 1239

1% = 1239 ÷ 118 = Rs 10.50

Find 100% (Price before GST):

1% = Rs 10.50

100% = 10.50 x 100 = Rs 1050

Answer: The price before GST is Rs 1050

Answer 2

Let the cost of article before adding GST be x.

After adding 18% GST, The price is

= x + 18% of x

= x + 0.18x

= 1.18x

According to the question,

1.18x = 1239

118x = 1239 * 100

x = 1050 .

Therefore , The cost of the article before adding the GST or the original price is 1050 Rupees.
