Explanation:

Between 100 and 300, the number of numbers ending with 2 will be
102, 112, ..... 192 (Total 10)
202, 212, ..... 292 (Total 10)
Between 100 and 300, the number of numbers beginning with 2 will be
200, 201, 202, ..... 299 (Total 100) of which 10 end with 2 so subtract that.
So final answer = 100 - 10 + 10 + 10 = 110.
