I am not even I am greater than 200 the sum of my digits is nine i am a multiple of five I am less than 300 I am evenly divisible by nine

I am NOT even, and I am a multiple of 5 > must end in 5
must look like AB5
must be between 200 and 300 ,so A = 2
must look like 2B5
to be divisible by 9 , the sum of the digits must be a multiple of 9
so 2+B + 5 = a multiple of 9
B = 2
your number is 225
check for all the required properties. 
225
