Question

What is the compound interest on Rs.1600 at 20% per annum for 1 years compounded half yearly.​

Answer 1

Answer:     Compound Interest= 168 . 2RS.

Step-by-step explanation:

M=A(1+r/100)*n

here-

r=10%/2=5%

t=(1+1/2)/1/2=3/2/1/2=3years

M=1600(1+5/100)*3

=1600(1+1/20)*3

=1600×(21/20)*3

=1600×21×21×21/20×20×20

by calculating we get-

M=1768.2Rs.

I=M-A

=1768.2-1600

=168.2Rs.
