\n" ); document.write( "Present age of Ann = a
\n" ); document.write( "Present age of Kim = k\r
\n" ); document.write( "\n" ); document.write( "Ann age is three times kims
\n" ); document.write( "a=3k.......(1)\r
\n" ); document.write( "\n" ); document.write( "In four years
\n" ); document.write( "Ann will be = a+4
\n" ); document.write( "Kim will be = k+4
