Let time taken by hose A to fill the pool = A hrs
\n" ); document.write( "time taken by hose B = B hrs
\n" ); document.write( "and time taken by both hoses together = C hrs \r
\n" ); document.write( "\n" ); document.write( "According to the formula
\n" ); document.write( "\"1%2FA%2B1%2FB=1%2FC\"\r
\n" ); document.write( "\n" ); document.write( "i.e. \"1%2F3%2B1%2FB=1%2F2\"
\n" ); document.write( "\"1%2FB=1%2F2-1%2F3\"
\n" ); document.write( "\"1%2FB=%283-2%29%2F6\"
\n" ); document.write( "\"1%2FB=1%2F6\"\r
\n" ); document.write( "\n" ); document.write( "this means B = 6 hrs\r
\n" ); document.write( "\n" ); document.write( "So hose B takes 6 hours to fill the pool.
\n" ); document.write( "
