  1. You probably mean
    "All my other digits are the same."

    "I am five digit number greater than 40,000 but less than 60,000."
    means that the first digit is either 4 or 5.

    "My ones digit is 3 more than my ten thousands digit"
    means that the first and last digits are either
    a) "4XXX7", or
    b) "5XXX8"

    "All my other digits are the same."
    means that the three middle digits are the same.

    "The sum of my digit is 28.What number I am?"
    means that
    a) 28 - (4+7) must be divisible by 3
    Since 17 is not divisible by 3, so it must be the other case
    b) 28 - (5+8)=15, so the middle digits are 555, or the 5-digit number is
    55558.
