Question

The S.I. on a sum of money for 2 years at 12% p.a. is 1380.Find the C.I. on this sum for one year half yearly at the same rate

Answer 1

Answer:

S.I=1380,T=2yr,R=12%

S.I=p*r*t/100

1380=p*12*2/100

p=1380*100/12*2

p=5750

for c.i

p=5750,r=12%,t=1yr on half yearly

amount =p(1+r/2*100)^2*t

=5750(1+12/200)^2*1

=5750(212/200)^2

=5750(27/25)^2

=5750*27/25*27/25

=33534/5

=6706.8

C.I=A-P

=6706.8-5750

=956.8
