Let\r
\n" ); document.write( "\n" ); document.write( "Grandfather's present age = g
\n" ); document.write( "Granddaughter present age = d\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Grand father is 10 times older than his granddaughter.\r
\n" ); document.write( "\n" ); document.write( "g=10d.........(1)\r
\n" ); document.write( "\n" ); document.write( "He is also 54 older than her
\n" ); document.write( "g=d+54..........(2)\r
\n" ); document.write( "\n" ); document.write( "Subtitute the value of g from (1) to (2)\r
\n" ); document.write( "\n" ); document.write( "10d=d+54
\n" ); document.write( "10d-d=54
\n" ); document.write( "9d=54
\n" ); document.write( "9d/9=54/9
\n" ); document.write( "d=6
\n" ); document.write( "Subtitute the value of d in (1)
\n" ); document.write( "g=10d
\n" ); document.write( "g=(10)(6)
\n" ); document.write( "g=60\r
\n" ); document.write( "\n" ); document.write( "Grandfather's present age = g = 60 years old
\n" ); document.write( "Granddaughter present age = d = 6 years old\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
