    The ratio of weekly incomes of A and B is 9: 7 and the ratio of their expenditures is 4: 3. If each saves Rs. 200 per week, then the sum of their weekly incomes is

    A) Rs. 3600                       

    B) Rs. 3200

    C) Rs. 4800                       

    D) Rs. 5600

    Correct Answer: B

    Solution :

    Let incomes of A and B are Rs. 9x and Rs. 7x, respectively.
    \[\therefore \]      \[\frac{9x-200}{7x-200}=\frac{4}{3}\]
    \[\Rightarrow \]   \[27x-600=28x-800\]
    \[\Rightarrow \]   \[x=200\]
    Hence, required sum \[=\,\,9x+7x\]
                                   \[=16\times 200=Rs.\,3200\]
