    and C in ratio of 3:4:5 respectively but due to some reason the money was falsely distributed in ratio of 4:3:5 respectively such that B received Rs. 2400 less. Find the value of 2K.
    A ₹57600 Correct Answer Incorrect Answer
    B ₹55200 Correct Answer Incorrect Answer
    C ₹60000 Correct Answer Incorrect Answer
    D ₹56400 Correct Answer Incorrect Answer
    E ₹58800 Correct Answer Incorrect Answer

    Solution

    Let the total amount [K] be Rs. 12x
    So, amount which B was supposed to receive = 12x × (4/12) = Rs. 4x
    Amount which was actually received by B = 12x × (3/12) = Rs. 3x
    ATQ,
    4x - 3x = 2400
    ⇒ x = 2400
    Also,
    K = 12x = 12 × 2400 = Rs. 28800
    Therefore, required value,
    2K = 2 × 28800 = ₹57600
