Marked price = ₹15000
15% discount = 15000 × 15/100 = ₹2250
Selling price = 15000 - 2250 = ₹12750
Gain = 15%
Cost price = SP × 100/(100+gain%)
=> CP = 12750 × 100/115
=> CP = ₹11087
Cost price of tv is ₹11087
15% discount = 15000 × 15/100 = ₹2250
Selling price = 15000 - 2250 = ₹12750
Gain = 15%
Cost price = SP × 100/(100+gain%)
=> CP = 12750 × 100/115
=> CP = ₹11087
Cost price of tv is ₹11087
