\n" ); document.write( "

Let new price be N\r\n" );
document.write( "Then old price = N - 6\r\n" );
document.write( "Then we get: \r\n" );
document.write( "              7(2N) = 3(5N - 30) ----- Cross-multiplying\r\n" );
document.write( "                14N = 15N - 90\r\n" );
document.write( "          14N - 15N = - 90\r\n" );
document.write( "                - N = - 90\r\n" );
document.write( "    New price or \r\n" );
document.write( "    That's IT!!
