If the compound interest on a certain sum at 1623 % to 3 years is Rs.1270, find the simple interest on the same sum at the same rate and f or the same period.

Correct Answer: 1080

Explanation:

Let the sum be Rs. x. Then,


 


  C . I = x * 50 300 * 100 3 - x = 343 x 216 - x = 127 x 216  


 


127 x 216 = 1270  


 


x = 2160  


 


Thus, the sum is Rs. 2160


 


  S . I = R s . 2160 * 50 3 * 3 * 1 100 = R s   1080
