Let the number of A stock be a
\n" ); document.write( "and the number of B stock be b\r
\n" ); document.write( "\n" ); document.write( "Now one share of A stock is worth 31/2 shares of B stock
\n" ); document.write( "=> a = 3 1/2 b
\n" ); document.write( "=> a = 7/2b\r
\n" ); document.write( "\n" ); document.write( "Now
\n" ); document.write( "a + b = 9000
\n" ); document.write( "=> 7/2b + b = 9000
\n" ); document.write( "=> 9/2b = 9000
\n" ); document.write( "=> b = 2000
\n" ); document.write( "=> a = 7/2*2000 = 7000\r
\n" ); document.write( "\n" ); document.write( "So in stock A $7000 is invested and in stock B $2000 is invested
\n" ); document.write( "
\n" );
