document.write( "1 job can be done by 25 men in 32 days.\r\n" );
document.write( "\r\n" );
document.write( "So when they had worked 8 days, they had done th of the job, since 8 is\r\n" );

document.write( "\r\n" );
document.write( "So that left  of the job for the 20 to do.\r\n" );
document.write( "\r\n" );
document.write( "Also since a job can be done by 25 men in 32 days,\r\n" );
document.write( "\r\n" );
document.write( "then 1 man would take 25 times as long or 800 days.\r\n" );
