    A)  Rs.1000

    C)                     Rs.1500             

    D)         Rs.1800

    Correct Answer: B

    Solution :

    Let income of \[A=Rs.3x,\]income of \[B=Rs.2x\] and expenditure of \[A=Rs.5y,\]expenditure of \[B=Rs.3y\] Now, saving = income - expenditure \[\therefore \] \[3x-5y=2x-3y=200\] \[\Rightarrow \]   \[x=2y\]and  \[y=200\] \[\therefore \]      \[x=400\] \[\therefore \] A's income =Rs.1200
