Given :  the SI on a sum of money for 3 years at 12 1 by 2% per annum is 1500  

To find : what will be the CI on the sum at the same rate and for the same period

$Solution:$

$Let \: \: \: say \: \: \: Sum \: \: of \: \: Money  =  P$

$Rate \: \: of \: \: interest  = 12  1/2  = 12.5  percent \:$

$Time = 3  Years$

$Simple \: \: \: interest =  P * 12.5 * 3 /100  = 1500$

$=> P = 4000$

$CI  = 4000 ( 1  +  12.5/100)³ - 4000$

$=> CI = 1695.31$

CI on the sum at the same rate and for the same period = Rs 1695.31
