Answer 2

Given : 2400   रु. 5 % वार्षिक दर

P = 2400

R =  5 % per annum

To Find : चकवृध्दि व्याज

Compound interest

Solution:

A = P(1 + R/100)ⁿ  

चकवृध्दि व्याज = A - P

P = 2400

R = 5 %

n = Times in years

चकवृध्दि व्याज  = 2400 ( 1 + 5/100)ⁿ - 2400

=> चकवृध्दि व्याज  = 2400 ( 1 + 1/20)ⁿ - 2400

=> चकवृध्दि व्याज  = 2400 ( 21/20)ⁿ - 2400

चकवृध्दि व्याज  = 2400 ( 21/20)ⁿ - 2400
