\n" ); document.write( "\n" ); document.write( "According to the condition,  the product   (number of workers) x (duration of construction in days) = constant,   is the constant value.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, you can solve the problem as follows.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It takes  10 people x 40 days = 400 people-days to build the house.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence,  8  people can build the house in  \"400%2F8\" = 50 days.\r
\n" ); document.write( "
