The genuine music discs produced by an audio-visual company sell for 50 yuan each, making a profit of 15 yuan. However, it is found that pirated products sell for only 20 yuan each. 
If there are no pirated discs, the sales volume of genuine discs produced by the company will not be less than 100,000.
 if 100,000 pirated discs are sold, it will cause a loss of 1.5 million yuan to the audio-visual company.
