\n" ); document.write( " let :\r
\n" ); document.write( "\n" ); document.write( " simple interest = I
\n" ); document.write( " principal = P
\n" ); document.write( " rate of interest = R
\n" ); document.write( " time period = T\r
\n" ); document.write( "\n" ); document.write( " we know that I =(P*R*T)/T
\n" ); document.write( " SO, I = (500 * 4 * 1)/100
\n" ); document.write( " SO, I = 2000/100
\n" ); document.write( " SO, I = $20
\n" ); document.write( "
\n" );
