Answer 1

Answer:

The total compound interest is Rs.1655/-

Step-by-step explanation:

Main points to know ::

Compounded half yearly it means for every six months we need to calculate interest on interest that is compounded half yearly..

Per Annum means for 1 year interest given.

SOLUTION::

P=5000

R=20%

T= 1 1/2 years.

I=PTR

100

using this formula calculate interest for every 6 months.. 20% per Annum but here for 6 months it's is going to be 10%.

Answer 2

Step-by-step explanation:

P= 5000

• R= 20%
• T= 1 and half years(3/2 yrs)

A=P(1+r/200)^n

• Here,n means number of times or years

A=5000(1+10/100)^3

• A=5000(11/10)^3

A=5000×11/10×11/10×11/10

A=5×11×11×11

• A=6655

Now,

• C.I=A-P
• C.I=6655-5000
• C.I= 1655 (Ans)
