The difference between simple interest and compound interest on a certain sum of money for 3 years at 10% per annum is Rs. 124. Find the sum.
A. Rs. 5000
B. Rs. 3500
C. Rs. 4500
D. Rs. 4000

Correct Answer: Option D


Explanation:
Difference for 3 years = P * (R/100)^2 * (3 + R/100) => 124 = P * (10/100)^2 * (3 + 10/100) => 124 = P * (1/100) * (3.1) => 124 = P * 0.031 => P = 124 / 0.031 = Rs. 4000.
