Read Solution (Total 2)

Let the cost of price of DVD player be D
Profit percentage when he sells at Rs.2880 = Loss percentage when he sells at 1920
i.e., (2880-D) / D x 100 = (D - 1920) / D x 100
2880 -D = D – 1920
2880 + 1920 = D + D
4800 = 2 D
D = Rs. 2400

Cost price = Rs. 2400. He wants to make 30% profit. (In the absence of special mention profit is always calculated on cost price.)
The desired profit amount = 30% of Rs.2400 = (2400 x 30) / 100 = 720.
Hence, The selling price = CP + Desired Profit = 2400 + 720 = Rs. 3120.
