Question

on what sum wiil the ci for 3years 14by2%per annum compound be 3101.40 ​

Answer 1

Answer:

Rs. 12,800

Step-by-step explanation:

Note: I am not sure if you have provided the Rate of interest correctly. Question says 14/2% which is 7%.

But i will take 15/2% for calculation purposes.  

C.I = 3101.40

n = 3 yrs

R = 15/2 %

C.I = A - P

A = P(1 + R/100)ⁿ

A = P(1 + 15/200)³

   = P * (215/200)³

   = 1.2423P.

C.I = A - P = 1.2423P - P = 0.2423P

3101.40 =   0.2423P

P = 3101.40/0.2423

   = Rs. 12,800.
