    A ₹64800 Correct Answer Incorrect Answer
    B ₹63000 Correct Answer Incorrect Answer
    C ₹68400 Correct Answer Incorrect Answer
    D ₹61200 Correct Answer Incorrect Answer
    E ₹67200 Correct Answer Incorrect Answer

    Solution

    Let the total amount [K] be Rs. 18x
    So, amount which Ravi was supposed to receive = 18x × (5/18) = Rs. 5x
    Amount which was actually received by Ravi = 18x × (4/18) = Rs. 4x
    ATQ,
    5x - 4x = 1800
    ⇒ x = 1800
    Also,
    K = 18x = 18 × 1800 = Rs. 32400
    Therefore, required value,
    2K = 2 × 32400 = ₹64800
