Question
The marked price of a TV is 60% above its cost price. It
was sold after giving a discount of Rs. 300. If the difference between the cost price and the profit earned is Rs. 660, then find the marked price of the TV.Solution
ATQ, Let, the cost price of the TV = Rs. 100x The marked price of the TV = 100x × 160/100 = Rs. 160x The selling price of the TV = Rs. (160x − 300) CP + P = SP CP − P = 660 P = CP − 660 So, 100x + 100x − 660 = 160x − 300 200x − 660 = 160x − 300 200x − 160x = −300 + 660 40x = 360 x = 9 The marked price of the TV = 160 × 9 = Rs. 1440
