    annum compounded quarterly. The total amount she gets after 6 months is :
    A Rs. 8820 Correct Answer Incorrect Answer
    B Rs. 8880 Correct Answer Incorrect Answer
    C Rs. 8800 Correct Answer Incorrect Answer
    D Rs. 8802 Correct Answer Incorrect Answer

    Solution

    We know that, A = P (1 + R/10)n Here, the interest rate is 20% per annum, and interest is compounded quarterly. ∴ Interest rate per interest period is 20/4 = 5%. Also, the interest is calculated after six months, number of periods = 6/3 = 2 Amount = 8000 (1 + 5/100)2 => A = 8000 × 21/20 × 21/20 => A = Rs.8820
