    A invested Rs X in a scheme. After 6 months, B

    joined with Rs 2000 more than that of A. After an year, ratio of profit of B to the total profit was 3: 7. Find the value of X.
    A Rs. 2000 Correct Answer Incorrect Answer

    C Rs. 4000 Correct Answer Incorrect Answer
    D Rs. 8400 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Profit of B/Total Profit = 3/7 = ((X +2000 )×6)/(X × 12 + (X +2000 ) × 6)
    9X + 6000 = 7X + 14000
    2X = 8000
    X = 4000
