    joined with Rs 10000 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. 20000 Correct Answer Incorrect Answer

    D Rs. 84000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Profit of B/Total Profit = 3/7 = ((X +10000 )×6)/(X × 12 + (X +10000 ) × 6)
    9X + 30000 = 7X + 70000
    2X = 40000
    X = 20000
