A certain number of men can finish a piece of work in 10 days.
\n" ); document.write( " If however there were 10 men less, it will take 10 days more for the work to be finished.
\n" ); document.write( " How many men were there originally?
\n" ); document.write( ":
\n" ); document.write( "let m = the original number of men
\n" ); document.write( "then
\n" ); document.write( "10m = the number of man-days required to complete the job
\n" ); document.write( ":
\n" ); document.write( "\"If there were 10 men less, it will take 10 days more for the work to be finished\"
\n" ); document.write( "That means that it would take 20 days
\n" ); document.write( "20(m-10) = 10m
\n" ); document.write( "20m - 200 = 10m
\n" ); document.write( "20m - 10m = 200
\n" ); document.write( "10m = 200
\n" ); document.write( "m = 200/10
\n" ); document.write( "m = 20 men originally
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this; find the number of man-hrs to do the job.
\n" ); document.write( "20*10 = 200 man-hrs (20 men working 10 days)
\n" ); document.write( "or
\n" ); document.write( "10*20 = 200 man-hrs (10 men working 20 days) \n" ); document.write( "
\n" );
