Question

Q12. Calculate the amount and
Compound interest on Rs.
18,000 for 2 1/2 years at
10%annum compounded
annually.​

Answer 1

Answer:

P=₹18000

T=2 1/2 years

R=10%

Compound Interest for 1st year

C.I=(P*R*T)/100

=(18000*10*1)/100

=180000/100

=₹1800

Amount=P+C.I

=18000+1800

=₹19800

Compound Interest for 2nd year

C.I=(P*R*T)/100

=(19800*10*1)/100

=198000/100

=₹1980

Amount=P+C.I

=19800+1980

=₹21780

Compound Interest for 2nd half year

C.I=(P*R*T)/100

=(21780*10*1)/(100*2)

=₹1089

Amount=P+C.I

=21780+1089

=₹22869

Compound Interest for 1st,2nd,2nd half year

C.I=1800+1980+1089

=₹4869

Therefore ,Compound Interest=₹4869 and Amount=₹22869
