    So the range of numbers is 100-199.

    Divisible by 12 it is an even number.

    Divisible by 9 the digits of the number add up to a number divisible by 9.

    So numbers that are divisible by 9 are:

    108
    117
    126
    135
    144
    153
    162
    171
    180
    189
    198

    That are also even and divisible by 12 are:

    108
    144
    180

    so which one complies with the last criteria?

    But check my working!
