The equation for simple interest calculation is
\n" ); document.write( "S.I. = (P * R * T)/100
\n" ); document.write( "where S.I. = simple interest
\n" ); document.write( " P = principal amount
\n" ); document.write( " R = rate of interest in percentage
\n" ); document.write( " T = time in years
\n" ); document.write( " '*' symbol denotes multiplication
\n" ); document.write( "
\n" ); document.write( "Therefore according to the problem
\n" ); document.write( " 270 = (1200 * 5 * T)/100
\n" ); document.write( "or 270 * 100 = 6000T
\n" ); document.write( "or T = 27000/6000 = 4.5yrs
\n" ); document.write( "
\n" ); document.write( "So the required time to get $270 as simple interest on $1200 @ 5%is 4years and 6months.
\n" ); document.write( "
