A=P(1+r/100)^n
P=Principal=10000
R=Rate of interest=7% p.a.
N=Time=2
A=Amount
A=10000(1+7/100)^2
A=10000*(107/100)^2
A=10000*11449/10000
A=11449
(i) Amount is rs. 11449
(ii) C.I.=P[(1+R/100)^N-1]
C.I.=10000[(1+7/100)^3-1]
C.I.=10000[(107/100)^3-1]
C.I.=10000*[1225043/1000000-1]
C.I.=10000*225043/1000000
C.I.=225043/100
C.I.=2250.43
(ii)Answer is 2250.43
