Find the compound interest on Rs. 50000 for 1 year at 8% per annum, compounded quarterly. MCQ with Answer and Explanation

Find the compound interest on Rs. 50000 for 1 year at 8% per annum, compounded quarterly.
A. Rs. 4121.61
B. Rs. 4200.00
C. Rs. 4000.00
D. Rs. 4310.20
Answer: Option A
Solution (By JKSSB Mock Tests)
Quarterly rate = 8 / 4 = 2%. Time = 4 quarters. Amount = 50000 * (1 + 2/100)^4 = 50000 * (1.02)^4 = 50000 * 1.08243216 = Rs. 54121.61. Compound Interest = 54121.61 - 50000 = Rs. 4121.61.
