Formula for calculating percentage gain is:\r
\n" ); document.write( "\n" ); document.write( "\"%28P%2FCP%29%2A100\"%
**Do not change the \"%\" sign**\r
\n" ); document.write( "\n" ); document.write( "Where,
\n" ); document.write( "\"P+=+Profit%3B\"
\n" ); document.write( "\"CP+=+Cost+Price\"\r
\n" ); document.write( "\n" ); document.write( "From question,
\n" ); document.write( "\"CP+=+%24400\"
\n" ); document.write( "\"P+=+SP+-+CP+=+%24480-+%24400+=+%2480\"\r
\n" ); document.write( "\n" ); document.write( "%Gain = \"%2880%2F400%29%2A100\"%

\n" ); document.write( "%Gain = \"%2880%2A100%29%2F400\"%

\n" ); document.write( "%Gain = \"8000%2F400\"%

\n" ); document.write( "%Gain = \"20\"%\r
