Let the number be x
\n" ); document.write( "65% of the number is 21 less than four fifth of that number.
\n" ); document.write( "Hence, x*(65/100) = x*(4/5) - 21
\n" ); document.write( "x * (4/5 - 65/100) = 21
\n" ); document.write( "x * (80/100 - 65/100) = 21
\n" ); document.write( "x * (15/100) = 21
\n" ); document.write( "x = 21 * 100 / 15 = ( 7 * 3 * 20 * 5 ) / ( 5 * 3) = 140
\n" ); document.write( "Hence, x = 140
\n" ); document.write( " \n" ); document.write( "

\n" );
