2 | = 1348.32 |
| 100 |
 |
|
1 + | R | |
2 | = | 134832 | = | 11236 |

Divide numerator and denominater by 100 to take out point. Tahts why 1200 as 120000.

Shakti borrows an amount of Rs 28000 for 2 years from a bank at a subsidised rate. At the end of 2 years he pays a sum of Rs 30870. How much was the rate of interest? What is the amount that should be paid if Shakti pays it after 3 years?
Solve it please?
