    B ₹11,178 Correct Answer Incorrect Answer
    C ₹16,600 Correct Answer Incorrect Answer
    D ₹18,976 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Money donated for disaster relief = 0.15 × 20000 = Rs. 3,000

    Remaining amount = 20000 – 3000 = Rs. 17,000

    Money donated for rural education = 0.10 × 17000 = Rs. 1,700

    Remaining amount = 17000 – 1700 = Rs. 15,300

    Money donated for orphan care = 0.30 × 15300 = Rs. 4,590

    Final amount left = 15300 – 4590 = Rs. 10,710
