    B 288 Correct Answer Incorrect Answer
    C 194 Correct Answer Incorrect Answer
    D 229 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the number of ₹2, ₹1 and 50-paise coins be 4x, 6x and 8x respectively.

    ATQ:

    (4x × 2) + (6x × 1) + (8x × 0.50) = 576

    Or, 8x + 6x + 4x = 576

    Or, 18x = 576

    Or, x = 576 / 18 = 32

    So, number of 50-paise coins = 8x = 8 × 32 = 256
