At what rate percent per annum will Rs. 2304 amount to Rs. 2500 in 2 years at compound interest?
A. 4.5%
B. 4.16%
C. 4%
D. 4.34%
Answer: Option C
Solution (By JKExamLibrary)
Amount/Principal = 2500 / 2304 = (50 / 48)^2 = (25 / 24)^2. Thus, 1 + R/100 = 25/24 => R/100 = 1/24 => R = 100/24 = 4.16%. Correct option is B.
