You can put this solution on YOUR website!
The interest formula you need is Interest = (Principal)*(rate)*(time)\r
\n" ); document.write( "\n" ); document.write( "For Kishan you have Principal is 3000, rate is \"x\", time is 3yrs.
\n" ); document.write( "So Kishan interest is 9000x\r
\n" ); document.write( "\n" ); document.write( "For Uma you have Principal is 1800, rate is \"(x+0.02)\", time is 3yrs.
\n" ); document.write( "So Uma interest is 5400(x+0.02) = 5400x + 108\r
\n" ); document.write( "\n" ); document.write( "Equation:
\n" ); document.write( " Kishan int. + Uma int. = 1836
\n" ); document.write( " 9000x + 5400x +108 = 1836
\n" ); document.write( " 14400x = 1836
\n" ); document.write( " x = 0.12
\n" ); document.write( "So, the two interest rates are 12% and 14%\r
