Algebra.Com's Answer #471106 by pakhi(24)![]() ![]() You can put this solution on YOUR website! 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( " |
