Answer 1

Answer: The answer is 5%

Step-by-step explanation: The increase in value is 105 - 100 which is RS 5.00

Therefore, the rate% is 5/100% i.e 5%

To verify just add 5% of 100 to 100 to check weather we get RS105.00

i.e. (5/100*100)+100 = (0.05*100)+100 = 5 + 100 = 105, hence verified.

Answer:

Poisson Summation Formula states that: ∑∞k=−∞f(2πk)=12π∑∞k=−∞f^(k).
