    Solution:

    Given number of boxes is 7924.
    Calculating square root by division method.
    ∴7924= 89.01
    Hence, the perfect square number smaller than 7924 is 892=7921.
    The next perfect square number is 902=8100.
    So, 8100-7924=176.
    Therefore, Mr. Hansraj needs 176 more boxes in order to get a perfect square number.
    Therefore, option (4) is correct.
