An employer employs 28 men to complete a work in 30 days.
\n" ); document.write( " 40% of work has been completed in 16 days.
\n" ); document.write( " How many more men required to complete the remaining work.
\n" ); document.write( ":
\n" ); document.write( "Find how many man-days required to complete 40% of the job
\n" ); document.write( "28 * 16 = 448 man-days
\n" ); document.write( "At this rate find how many man-days (md)required to complete the job\
\n" ); document.write( ".4md = 448
\n" ); document.write( "md = 448/.4
\n" ); document.write( "md = 1120 man-days to complete the job
\n" ); document.write( "therefore
\n" ); document.write( "1120 - 448 = 672 man-days to do the remaining 60% in 14 days
\n" ); document.write( "Find the no. of men required
\n" ); document.write( "672/14 = 48 total men
\n" ); document.write( "48 - 28 = 20 more men to finish the job on time

\n" ); document.write( ":
\n" ); document.write( "I said that 28 * 16 = 448 man-days represents 40& of work. So from this we can
\n" ); document.write( "find how many man-days for 100%
\n" ); document.write( "40% of the total man-days = 448
\n" ); document.write( "which is
\n" ); document.write( ".40md = 448
\n" ); document.write( "Find md
\n" ); document.write( "md = 448/.4
\n" ); document.write( "md = 1120 man-days for 100% of the work \n" ); document.write( "
