what is my number
I am a three digit number
I am less than 200
i am divisible by 12 and by 9
my units digit is less than my tens digit

So the range of numbers is 100199.
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! 
180

what is the answer

153

180
