Google - I am greater than 100, the sum of my digits is 13, I am less than the number of years in 2?

175.

Between one and two hundred, so you know it starts with a one.
It is a multiple of 5 so it has to end with either zero or five.
The digits add up to 13 (so it must end in five), now you just figure out what to add to the space between 1_5 to make 13 in total, 7.
1+7+5=13.
