    A sum of Rs. 5000 was lent partly at 6% and partly at 9% simple interest. If the total interest received after one year 1 was Rs. 390, the ratio in which the money was lent at 6% and 9% is

    A) 1 : 1                             

    B) 3 : 2

    C) 2 : 3                 

    D) 1 : 2

    Correct Answer: C

    Solution :

    Let the first part is Rs. x and another part is \[Rs.(5000-x)\] According to question, \[\frac{x\times 6\times 1}{100}+\frac{(5000-x)\times 9\times 1}{100}=390\] \[\Rightarrow \]   \[6x+45000-9x=39000\] \[\Rightarrow \]                    \[-\,3x=39000-45000\] \[\Rightarrow \]   \[x=\frac{6000}{3}=2000\] \[\therefore \]      First part \[=Rs.\,2000\] and second part \[=Rs.\,3000\] \[\therefore \]      Required ratio \[=2:3\]
