Xinglong Electric Store sells DVD players of the same model at a profit of 20% of the purchase price. After selling these appliances, the profit can be 6,000 yuan. Since 10 of the DVD players have some damage on the outside, these 10 DVD players will be sold as 10% off the price, so the total profit is only 96% of the estimate.
