document.write( "Their combined rate of work is  \"1%2F60+%2B+1%2F40\" = \"2%2F120+%2B+3%2F120\" = \"5%2F120\" = \"1%2F24\".\r\n" );

document.write( "\r\n" );
document.write( "So, the time to complete the job would be 24 days, had they work together.\r\n" );

document.write( "\r\n" );
document.write( "But A left the job after 14 days working together.\r\n" );
document.write( "\r\n" );

document.write( "After 14 days working together, they completed  the part of  \"14%2F24\" = \"7%2F12\"  the job;\r\n" );

document.write( "hence,  \"5%2F12\"  of the job remained.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Worker B completed the remaining part of the job in  \"%28%285%2F12%29%29%2F%28%281%2F40%29%29\" = \"%285%2A40%29%2F12\" = \"200%2F12\" = \"50%2F3\" days = 16 2/3  days.\r\n" );
