The difference between simple interest and compound on Rs. 1200 for one year at 10% per annum reckoned half-yearly is:
Answer: Option
Explanation:
| S.I. = Rs |  |
1200 x 10 x 1 |  |
= Rs. 120. |
| 100 |
| C.I. = Rs. |  |
1200 x | |
1 + | 5 | |
2 | - 1200 |  |
= Rs. 123. |
| 100 |
Difference = Rs. (123 - 120) = Rs. 3.

Friends,
They told to calculate for 1 year.
Given data is half yearly.
The reason why they calculated for SI without changing the rate of interest is as in the concept of SI the interest rate won't change (constant) so they kept same.
While in CI they changed because it won't be constant. This is the reason guys.

For one year there both SI and CI remains same. Then how come its possible?

Hi friends this might be help you.
In both the cases we should take time 1 year means t = 1 for S.I. and n = 1 for C.I.
But half-yearly data is only given for C.I so, the formula changed for C.I .as per compounded half-yearly.

Why we have raised the power to 2 in calculating CI?

Here we are taking for only single half year so, n=1 then 2n=2*1=2.

It is mentioned in the question SI-CI so they have just subtracted.
