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.

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.

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.

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.
