The correct option is B 2 gain %
Let the cost price (CP) be Rs 100
Marked price = CP + 20% of Cost Price
Marked Price =(100+20)% of 100=100+20100×100=120
Discount of 15% on marked price is given
Hence, selling price = Marked Price - 15% of Marked Price
Selling Price = 120−15100×120 = 120−18= Rs 102
Profit =SP−CP=102−100=Rs 2
Now, Profit Percent =ProfitCP×100=2100×100=2%
