Whether you sell one book or 12 books the profit percentage will be the same\r
\n" ); document.write( "\n" ); document.write( "Selling price = 85\r
\n" ); document.write( "\n" ); document.write( "Cost price = 50\r
\n" ); document.write( "\n" ); document.write( "85-50 = 35\r
\n" ); document.write( "\n" ); document.write( "Profit percent = (profit/ cost price ) * 100\r
\n" ); document.write( "\n" ); document.write( "= 35/50 * 100 = 70\r
\n" ); document.write( "\n" ); document.write( "70 % is the profit percentage\r
\n" ); document.write( "\n" ); document.write( "
