\n" ); document.write( "when should 5 men leave the work, if the whole field is to be reaped in 24 days after they leave the work.
\n" ); document.write( "let d = no. of days until the remaining 15 men finish in 24 days
\n" ); document.write( "5d + 15(d+24) = 400
\n" ); document.write( "5d + 15d + 360 = 400
\n" ); document.write( "20d = 400 - 360
\n" ); document.write( "20d = 400 - 360
\n" ); document.write( "20d = 40
