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

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?

For taking difference we have to solve for either one year or half year.

On the account of half-yearly, the value of n in S.I would be 1/2 only na?

Why in CI it is raised to 2 and not 1. => 2n= 2x(1/2) ?
Why SI calculated for yearly and not half yearly ?

Simple Interest (S.I.):
If the interest on a sum borrowed for certain period is reckoned uniformly, then it is called simple interest.
So pnr/100 is used.
