dude those values are not C.I ....and
Rate=[(A2/A1)^1/(t2-t1)-1]*100
so rate will be 20% and sum 12000

Principal Amount = 12000

THE DIFFERENCE BETWEEN THE TWO amount WILL GIVE THE c.i BTWEEN THE 2 YRS
THAT IS,20736-17280=3456.
RATE=(17280/3456)*100=20%
LET THE SUM BE X,
17280=X(1+20/100)^2
X=12000

The Sum Will Be 72000 Not 12000, Sine 17280 & 20736 are CI(Compound Interest) Not The (Sum+CI)..
