    I am thinking of a 6-digit number. The sum of the digits is 43.

    And only two of the following three statements about the number are true:

    (1) it's a square number,
    (2) it's a cube number, and
    (3) the number is under 500000.

    Solution
    Only Statements 1 and 3 are true. the number is 499849.

    7072 = 499849
    499849<500000
