You can put this solution on YOUR website!
Nine employees working at the same rate require 15 days to complete a task.
\n" ); document.write( "Find the no. of man-hrs required
\n" ); document.write( "9 * 15 = 135 man-hrs to do the job
\n" ); document.write( ":
\n" ); document.write( " Which formula indicates how long it would take to do the same work if there were 3 additional employees each capable of working twice as fast as each of the original 9 employees?
\n" ); document.write( ":
\n" ); document.write( "The 3 additional employees would be the same as 6 of the original employees
\n" ); document.write( "Let d = no. of days required by this group
\n" ); document.write( "9 + 6 = 15 men effectively
\n" ); document.write( "15d = 135
\n" ); document.write( "d = 135/15
\n" ); document.write( "d = 9 days with this group \n" ); document.write( "

\n" );
