    What will be the amount of Rs. 2560 at the rate of interest of 25% for 6 months, if interest calculated per quarter?

    A) Rs. 3320

    B) Rs. 8290

    C) Rs. 2980

    D) Rs. 2890

    Correct Answer: D

    Solution :

    [d] \[\because \]P = Rs. 2560, r = 25% yearly \[=\frac{25}{4}%\] per quarterly and n = 6 months = 2 quarterly \[\therefore \]      \[A=P{{\left( 1+\frac{r}{100} \right)}^{n}}\]             \[=2560{{\left( 1+\frac{25}{400} \right)}^{2}}\]             \[=2560{{\left( \frac{17}{16} \right)}^{2}}\]             \[=\frac{2560\times 17\times 17}{16\times 16}=\text{Rs}.\,\,2890\]
