Question

An article was purchased for Rs1239 including GST of 18%.Find the price of the article before GST was added??​ i will mark it as brainliest but don't spam

Answer 1

Cost with gst included = rupees 1239

Cost with out gst = x rupees

gst = 18%

If we take this into equation -

x + ( ( 18 ÷ 100 ) × x ) = 1239

cost before gst + gst = cost with gst

x + ( 9x ÷ 50 ) = 1239

( 50x + 9x ) ÷ 50 = 1239

59x ÷ 50 = 1239

59x = 1239 × 50

59x = 61950

x = 61950 ÷ 59

x = 1050

Price before GST = 1050 rupees

Hope this help!!
