Correct question : An article was purchased for ₹1239 including GST of 18%.

To find : What is the price of the article before GST was added.

Solution : After 18% was adding (100 + 18 = 118℅) but before the GST was added the percentage would be 100% and we have to find thr price of article when it was 100%.

Using UNITARY METHOD :

Finding the cost of article for 1% :

:\implies\sf{1 \% = \dfrac{1239}{118}}:⟹1%=

118

1239

:\implies{\sf{\underline{\boxed{\sf{1\% = 10.50}}}}}:⟹

1%=10.50

Finding the cost of article before adding GST :

:\implies\sf{100\% = (10.50 \times 100)}:⟹100%=(10.50×100)

:\implies{\sf{\underline{\boxed{\sf{100\% = 1050}}}}}:⟹

100%=1050

Therefore, ₹1050 is the cost of article before GST was added.......
