Let x=amount of time it takes to finish off the garage
\n" ); document.write( "It takes 7*10=70 man-days to build the garage
\n" ); document.write( "Halfway through building the garage would take 5 days; 7*5=35 man-days
\n" ); document.write( "This would leave 35 man-days to complete by 7+3=10 men
\n" ); document.write( "Soooo 10x=35
\n" ); document.write( "x=3.5 days------ time to finish off the garage (a)
\n" ); document.write( "5+3.5=8.5 days----time to build the garage altogether (b)\r
\n" ); document.write( "\n" ); document.write( "BTW, one man takes 70 days to build the garage\r
