    Amount incomes of A and Bare in the ratio 4 : 3 and their annual expenses in the ratio 3 : 2. If each saves Rs. 60000 at the end of the year, the annual income of A is

    A)  Rs. 120000      

    B)  Rs. 150000

    C)  Rs. 240000      

    D)  Rs. 360000

    Correct Answer: C

    Solution :

    Let the annual incomes of A and B Rs. 4x and Rs. 3x and their expenses be Rs. 3y and Rs. 2y, respectively. \[\therefore \]      \[4x-3y=6000\]                          ...(i) And      \[3x-2y=6000\]                          ...(ii) Clearly,\[4x-3y=3x-2y\Rightarrow x=y\] From Eq. (i), x= 60000 \[\therefore \]A's annual income\[=4x=4\times 60000\]       = Rs. 240000
