\n" ); document.write( ":
\n" ); document.write( "Let n = no. of members in the team
\n" ); document.write( "Use the decimal equiv of per cent
\n" ); document.write( ":
\n" ); document.write( ".10(.25n) = 2
\n" ); document.write( ".025n = 2
\n" ); document.write( "n = 2/.025
\n" ); document.write( "n = 80
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check, 25% of 80 is 20, 10% of 20 is 2
\n" ); document.write( " \n" ); document.write( "

\n" );
