\r\n" );
document.write( "Let \"n\" be the (unknown) number of workers.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the rate of work was    lamps per worker per month BEFORE increasing.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the other side,  the rate of work became    lamps per worker per month AFTER increasing.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the condition, we know that the difference in the rate of work is 40 lamps per worker per month.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It gives you an equation\r\n" );

document.write( "     -  = 40,\r\n" );

document.write( "\r\n" );
document.write( "     = 40,\r\n" );

document.write( "    n =  = 5.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The number of workers is 5.\r\n" );
