Find the compound interest on Rs. 10000 for 1 year at 8% per annum, compounded quarterly. MCQ with Answer and Explanation

Find the compound interest on Rs. 10000 for 1 year at 8% per annum, compounded quarterly.
A. Rs. 840.00
B. Rs. 800.00
C. Rs. 824.32
D. Rs. 850.50
Answer: Option C
Solution (By JKSSB Mock Tests)
Quarterly rate = 8 / 4 = 2%. Time = 4 quarters. Amount = 10000 * (1 + 2/100)^4 = 10000 * (1.02)^4 = 10000 * 1.082432 = Rs. 10824.32. Compound Interest = 10824.32 - 10000 = Rs. 824.32.
