Question

an article was purchased for Rs1239 including GST of 18percent. Find the price of the article before GST added ?

Answer 1

Total price = price + tax  

100 = price + 18  

Price = 100-18 = 82%  

Price = 1239×82/100

= 1015.98

= 1016 rs

Answer 2

given,
article was purchased for Rs.1239.

so ,market price of article = Rs.1239

G.S.T paid = 18℅ of 1239

= 18 / 100 × 1239

= 0.18 × 1239

= RS. 223.02

price of article before G.S.T added

= market price - G.S.T paid

= 1239 - 223.02

= Rs. 1015 .98

hence , answer = Rs.1015.98
