If the compound interest on a certain sum for 2 years at 12% per annum is Rs. 1590, find the simple interest on the same sum at the same rate for the same period. MCQ with Answer and Explanation

If the compound interest on a certain sum for 2 years at 12% per annum is Rs. 1590, find the simple interest on the same sum at the same rate for the same period.
A. Rs. 1450
B. Rs. 1500
C. Rs. 1550
D. Rs. 1400
Answer: Option B
Solution (By JKSSB Mock Tests)
Effective compound interest rate = 12 + 12 + (1212)/100 = 25.44%. Simple interest rate = 12 * 2 = 24%. Given 25.44% of sum = 1590 => Sum = 1590 / 0.2544 = Rs. 6250. Simple Interest = 24% of 6250 = Rs. 1500.
