Let S be the number of smaller font pages and L be the number of larget font pages.
\n" ); document.write( "There are 21 total pages.
\n" ); document.write( "1.\"S%2BL=21\"
\n" ); document.write( "The number of words per page is 1800 and 2400 respectively. The total number of words is 48000.
\n" ); document.write( "\"2400%2AS%2B1800%2AL=48000\"
\n" ); document.write( "\"24S%2B18L=480\"
\n" ); document.write( "2.\"4S%2B3L=80\"
\n" ); document.write( "Now use eq. 1 to get S in terms of L and substitute,
\n" ); document.write( "\"S%2BL=21\"
\n" ); document.write( "\"S=21-L\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"4S%2B3L=80\"
\n" ); document.write( "\"4%2821-L%29%2B3L=80\"
\n" ); document.write( "\"84-4L%2B3L=80\"
\n" ); document.write( "\"-L=-4\"
\n" ); document.write( "\"L=4\"
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( "\"S=21-L\"
\n" ); document.write( "\"S=21-4=17\"
\n" ); document.write( "17 small font pages and 4 large font pages.
\n" ); document.write( "
\n" );
