Find the compound interest on Rs. 10000 for 1 year at 4% per annum, compounded quarterly. MCQ with Answer and Explanation

Find the compound interest on Rs. 10000 for 1 year at 4% per annum, compounded quarterly.
A. Rs. 400.00
B. Rs. 412.20
C. Rs. 410.00
D. Rs. 406.04
Answer: Option D
Solution (By JKSSB Mock Tests)
Quarterly rate = 4 / 4 = 1%. Time = 4 quarters. Amount = 10000 * (1 + 1/100)^4 = 10000 * (1.01)^4 = 10000 * 1.04060401 = Rs. 10406.04. Compound Interest = 10406.04 - 10000 = Rs. 406.04.
