Question

the marked price of an article is rs.3500 and rate of GST is 12%. A shopkeeper allows a discount of 20% and still makes a profit of10%. Find the original CP of the article and the SP Including GST

Answer 1

Marked price (1-20/100) = Purchasing price (1+10/100)

3500*80/100 = P.P*110/100

2800 = 110/100*P.P

P.P = 2800*100/110

P.P = 2545.5

Original C.P = RS. 2545.5

S.P including G.S.T = 3500*20/100 = 420

3500+420 = RS. 3920.
