    D Rs. 3900 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Since, ‘A’ and ‘B’ invested their sums for equal period, therefore, ratio of the profit received by ‘A’ and ‘B’ will be equal to the ratio of sum invested by them i.e. 4:3, respectively Let the total profit received by them be Rs. 100x Therefore, profit distributed between ‘A’ and ‘B’ = 0.70 × 100x = Rs. 70x Profit received by ‘A’ = 70x × (4/7) = Rs. 40x According to the question, 40x = 1600 Or, x = 40 Therefore, total profit received by ‘A’ and ‘B’ = 100x = Rs. 4000
