    Question

    The contributions made by A and B are in the ratio of

    2:5. If 10% of total profit is donated and A gets 8100 as his share of profit, what is the total profit?
    A Rs. 30000.25 Correct Answer Incorrect Answer
    B Rs. 30000 Correct Answer Incorrect Answer
    C Rs. 38406.25 Correct Answer Incorrect Answer
    D Rs. 31500 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the total profit = x
    The ratio of contribution by A and B = 2:5
    Share of A = (2/7) × x = 8100
    x= (8100 × 7)/2
    Total profit: x = 28350
    A gets 8100 after 10% donated
    Now, 90% = 28350
    1% = 28350/ 90
    And, 100% = (28350/90) × 100 = 31500
