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.

Given that C.I formula for half-yearly as p[1+ (r/2) /100]^2n.
Then 2n means 2*1/2=1 but you are taken it as power 2 how it's possible?

Rs.1200 is invest, we needed only for compound interest. So we are subtracted Rs.1200.

Please can you explain Why they used n=1 for SI And N=1/2 for C.I ?

While calculating simple interest why we hav'nt considered half yearly. It has been calculate for yearly but compound interest is calculated for half yearly.

In simple interest, we charge interest on Principle amount only.
but in compund interest we charge interst on principle as well as interest recieved.
if you take R=5, then u have to take n=2, ans remain same.

Why rate in SI not taken 5 ?

Why 1200 is subtracted for calculation of CI?

How CI is calculated?

Thank you binnu.

Compound interest = p[1+(r/2)/100]^2n for half yearly.
So here they gave r=10% so r/2=5 according to the formulae.
