It will take 24 men working 9 hours a day each to build a house in 45 days. Given that all men work at the same rate,
\n" ); document.write( "a. How many days will 18 men take to build the same house if they work 8 hours a day ?
\n" ); document.write( "b. how many hours per day must 20 men work if the house is to be completed in 48 days ?
\n" ); document.write( "**
\n" ); document.write( "Man-hours to build the house=24*9*45=9720
\n" ); document.write( "a. How many days will 18 men take to build the same house if they work 8 hours a day ?
\n" ); document.write( "let x=days to build the same house
\n" ); document.write( "18*8*x=9720
\n" ); document.write( "x=9720/(18*8)=67.5 days
\n" ); document.write( "..
\n" ); document.write( "b. how many hours per day must 20 men work if the house is to be completed in 48 days ?
\n" ); document.write( "let u = hours per day 20 men must work
\n" ); document.write( "20*u*48=9720
\n" ); document.write( "u=9720/(20*48)=10.125 hrs/day
\n" ); document.write( "
\n" );
