    A sum of Rs. 1600 gives a simple interest of Rs. 252 in 2 yr and 3 months. The rate of interest per annum is

    A)  \[5\frac{1}{2}%\]         

    B)  8%

    C)  7%      

    D)  6%

    Correct Answer: C

    Solution :

    Given that  P = Rs. 1600, SI = Rs. 252 and t = 2 yr and 3 month \[=2\frac{1}{4}\,\,yr\] \[\therefore \]      \[252=\frac{1600\times r\times 9}{100\times 4}\] \[\Rightarrow \]   \[\,r=\frac{252\times 100\times 4}{1600\times 9}=7\] Required rate of interest = 7%
