It takes 20 men 60 days to complete a building work.\r
\n" ); document.write( "\n" ); document.write( "how many days longer would it take 15 men, assuming that they all work at the same rate (formula method)\r
\n" ); document.write( "\n" ); document.write( "In this problem itis a case of inverse proportion.\r
\n" ); document.write( "\n" ); document.write( "W1 *M1=W2*M2\r
\n" ); document.write( "\n" ); document.write( "20*60 = 15*x\r
\n" ); document.write( "\n" ); document.write( "(20/15) *60 =x
\n" ); document.write( "= 80 days
\n" ); document.write( "So 15 men will take 20 days more to complete the job
\n" ); document.write( "
\n" ); document.write( "
\n" );
