    Smile 5 digit number....

    Can you find a five digit number which has no zeros no digit is repeated, where:

    The first digit is a prime number.
    The second digit is the fifth digit minus the first digit.
    The third digit is twice the first digit.
    The fourth digit is the third digit plus three.
    The fifth digit is the difference between the first digit and the fourth digit.

    23475

    since it is a prime number and has to be a single digit, it should be 2,3, 5 or 7.
    Following the conditions we get the aforementioned number that has no digits repeating and has non zero numbers in it.

    Thanks,
