Given below are two statements : Statement I: The rate law for the reaction $$A + B \rightarrow C$$ is rate $$(r) = k[A]^2[B]$$. When the concentration of both A and B is doubled, the reaction rate is increased "$$x$$" times. Statement II : 

The figure is showing "the variation in concentration against time plot" for a "$$y$$" order reaction. The Value of $$x + y$$ is ______
