    The simple interest on a sum of money is \[\frac{1}{9}\] of the principal and the number of years is equal to the rate per cent per annum. The rate per cent per annum is

    A) \[\frac{100}{9}\]%                    

    B) \[\frac{10}{3}%\]%

    C) \[\frac{5}{3}%\]%                        

    D) None of these

    Correct Answer: B

    Solution :

    Let principal \[\Rightarrow \] \[x=1200=Rs.\,x\]and rate = r% Then, interest\[=\frac{1}{9}x\] and number of years = r             \[\frac{x}{9}=\frac{x\times r\times r}{100}\] \[\therefore \]      \[{{r}^{2}}=\frac{100}{9}=r=\frac{10}{3}\]
