What is the difference between the compound interests on Rs. 5000 for 1
years at 4% per annum compounded yearly and half-yearly?

Answer: Option
Explanation:
C.I. when interest compounded yearly |
|
|||||||||||||||
|
||||||||||||||||
= Rs. 5304. |
C.I. when interest is compounded half-yearly |
|
||||||||||||
|
|||||||||||||
= Rs. 5306.04 |
Difference = Rs. (5306.04 - 5304) = Rs. 2.04

How to decide 4% rate?

Compounded yearly:
P = 5000,
R = 4% -----> 200,
So, 5000 + 200 = 5200,
R = 2% -----> 104,
Then total = 5200 + 104 = 5304.
Compounded half-yearly:
P = 5000,
R = 2% -----> 100,
Then, 5000 + 100 = 5100,
R = 2% -----> 102,
Then, 5100 + 102 = 5202,
R = 2% -----> 104.04,
Total = 5202 + 104.04 = 5306.04.
And finally, 5304 - 5306.04 = 2.04.
P = 5000,
R = 4% -----> 200,
So, 5000 + 200 = 5200,
R = 2% -----> 104,
Then total = 5200 + 104 = 5304.
Compounded half-yearly:
P = 5000,
R = 2% -----> 100,
Then, 5000 + 100 = 5100,
R = 2% -----> 102,
Then, 5100 + 102 = 5202,
R = 2% -----> 104.04,
Total = 5202 + 104.04 = 5306.04.
And finally, 5304 - 5306.04 = 2.04.

(1+2/100)^3 in this, why this cube is taken in half yearly?

When interest is compounded half yearly and time is in fraction.
A = P(1 + r/2 * 100)^2n.
A = P(1 + r/2 * 100)^2n.

Just using a formula of the amount when the interest is compound half yearly, ie time =2n here n = 3/2 then,
2n = 3/2 * 2= 3.
2n = 3/2 * 2= 3.

Direct formula for finding the amount of compound interest.
A = P( 1 + R*t/100)^n/t.
Where,
A : Amount ( principle + interest).
P : principle amount.
R : rate of interest in %.
t : number of years for interested is compounded.
n : number of years.
In above example,
For the half year compounded t=1/2.
Try this method.
Thanks.

Here formula used for amount but question is for C.I? How?
So please check it.
