    Find the number consisting of 9 digits in which each of the digits from 1 to 9 appears only once. This number should satisfy the following requirements:

    a). The number should be divisible by 9
    b). If the right most digit is removed, the remaining number sould be divisible by 8.
    c). If then again the right most digit is removed, the remaining number sould be divisible by 7.
    d). Then by 6 and so on...... until the last remaining number of one digit should be divisible by 1.

    electron1212: I think your answer is wrong!!
    In your answer, after taking off the two right most numbers, the number 1472589 is not
    divisible by 7, as it should be. Miniy's answer is correct I guess!!
